At Zhongyu Woodcraft, we design and build museum-quality ancient Chinese trebuchet and catapult replicas for museums, theme parks, cultural sites, historical reenactment groups, film and television productions, and private collectors worldwide, with every component researched, engineered, and crafted using authentic materials and traditional techniques.

The History and Engineering of Ancient Chinese Siege Engines

The use of siege engines in China dates back over 2,500 years to the Spring and Autumn Period (770-476 BC), when the increasing sophistication of city fortifications led to the development of specialized siege weapons. The earliest Chinese siege engines were traction catapults (pao, /), also known as “trebuchets”

in Western terminology, which used a team of people pulling on ropes attached to the short end of a throwing arm to hurl projectiles from a sling at the long end. Unlike the counterweight trebuchet developed in the medieval Mediterranean, the Chinese traction trebuchet was operated by a crew of pullers, allowing for rapid fire and greater mobility. The Chinese traction trebuchet could hurl projectiles weighing 5-10 kg over distances of 100-200 meters, with a well-trained crew capable of firing every 15-30 seconds.

The most comprehensive historical record of Chinese siege engines is the Wujing Zongyao (, Compendium of Military Classics), compiled during the Song Dynasty in 1044 AD. This monumental military encyclopedia documents over 300 weapons and military technologies, including detailed descriptions and illustrations of various types of siege engines: 1) Whirlwind catapult (xuanfeng pao, ): A small, mobile catapult mounted on a rotating base, capable of 360-degree rotation without repositioning the entire engine.

Used for defense and for firing at moving targets. 2) Whirlwind catapult (xuanfeng pao, ): A small, mobile catapult mounted on a rotating base, capable of 360-degree rotation without repositioning the entire engine. Used for defense and for firing at moving targets. 3) Four-footed catapult (sijiao pao, ): A medium-sized catapult with a four-legged frame, providing greater stability and throwing power.

Used for both offensive and defensive siege operations. 4) Seven-footed catapult (qijiao pao, ): A large catapult with a seven-legged frame, providing maximum stability and throwing power. Used for breaching city walls and destroying fortifications. 5) Tiger crouching catapult (hudun pao, ): A low-profile catapult designed for concealment and close-range fire, named for its crouched tiger appearance.

6) Crouching mortar catapult (wodeng pao, ): A large, heavy catapult designed for maximum throwing power, operated by a large crew of pullers. 7) Hook and ladder cart (gouche, ): A siege vehicle with a long beam and hook used to pull down enemy walls and fortifications. 8) Siege tower (louche, ): A tall, wheeled tower used to assault city walls, with archers and soldiers on multiple levels.

9) Battering ram (chongche, ): A wheeled vehicle with a heavy ram used to break gates and walls. 10) Cloud ladder (yunti, ): A mobile, extendable ladder used to scale city walls.

During the Song Dynasty (960-1279 AD), siege technology reached its peak in China. The Song Dynasty faced constant threats from northern nomadic empires (Liao, Western Xia, Jin, Mongol) and invested heavily in defensive fortifications and siege technology. The Song military used large numbers of traction catapults for both city defense and field operations, with some battles involving hundreds of catapults on each side.

The famous siege of Xiangyang (1267-1273 AD) during the Mongol conquest of the Southern Song saw the use of massive counterweight trebuchets (known as “Muslim trebuchets” or huihui pao, ) introduced by the Mongols, which were capable of hurling projectiles weighing up to 100 kg over distances of 300-500 meters.

These massive counterweight trebuchets, designed by Persian and Muslim engineers, were instrumental in breaking the defenses of Xiangyang and Fancheng, ending the long siege and contributing to the fall of the Southern Song Dynasty. The introduction of the counterweight trebuchet to China during this period represents one of the most significant technological transfers in medieval history, and it led to the development of hybrid Chinese-Middle Eastern siege engine designs during the Yuan Dynasty (1271-1368 AD).

The engineering of the ancient Chinese traction trebuchet is a marvel of mechanical design. The basic components include: 1) Frame (jia, ): A sturdy wooden frame, typically with four or more legs, providing a stable base for the engine. The frame was often reinforced with diagonal braces and bound with rope or rawhide for additional strength.

2) Axle (zhou, ): A horizontal wooden or iron axle mounted on top of the frame, on which the throwing arm pivots. The axle was typically made of elm or oak for strength, or iron for heavy engines. 3) Throwing arm (gan, ): A long wooden arm that pivots on the axle, with the short end (about 1/4 to 1/5 of the total length) facing the pullers and the long end (about 3/4 to 4/5 of the total length) facing the target.

The throwing arm was typically made of elm or oak for strength and flexibility, and was often reinforced with iron bands or wrapped with rawhide. 4) Sling (shao, ): A rope sling attached to the end of the long arm, holding the projectile. The sling releases the projectile at the optimal angle for maximum distance, typically at about 45 degrees.

5) Pulling ropes (la sheng, ): Multiple ropes attached to the short end of the throwing arm, pulled by a crew of soldiers to provide the throwing force. The number of pullers varied from 10-20 for small catapults to 100-200 for large catapults. 6) Counterweight (for counterweight trebuchets): A heavy weight (typically stone or iron) attached to the short end of the throwing arm, providing the throwing force through gravity rather than human pulling.

Counterweight trebuchets could hurl much heavier projectiles much farther than traction trebuchets, but were slower to fire and less mobile. 7) Projectiles (dan, ): Stone balls, fire bombs (huoqiu, ), incendiary devices, or even dead animals or debris. Stone projectiles were typically spherical and weighed 1-100 kg depending on the size of the engine.

The mechanics of the traction trebuchet are based on the lever principle, with the throwing arm acting as a first-class lever. The pullers apply force to the short end, which is amplified by the lever ratio to produce a much greater velocity at the long end. The sling further increases the effective length of the arm and releases the projectile at the optimal angle for maximum distance.

A well-designed and well-operated traction trebuchet was a formidable weapon, capable of accurate, rapid fire over considerable distances, and it remained the primary siege weapon in China for over 1,500 years until the development of gunpowder artillery during the late Song and Yuan dynasties.

Rush orders may be possible for an additional fee, though traditional handcraftsmanship and proper drying/curing times require adequate time for quality. For clients with tight deadlines, we may have standard engines in stock or near completion that can be customized more quickly contact us to check current inventory.

Q: Can the engine actually throw projectiles, and is it safe for public demonstrations?

A: Yes, our functional full-scale siege engines are designed and built to actually throw projectiles, exactly as ancient engines did. We use authentic traditional designs and mechanics, with the throwing arm, sling, and release mechanism all functioning as they would have in ancient times. Before shipping, every functional engine is test-fired in our workshop with various projectile weights to verify that it performs correctly, the range and accuracy are as expected, the release mechanism works reliably, and there are no safety issues.

We make any necessary adjustments during testing to ensure optimal performance and safety. For public demonstrations (museums, theme parks, historical reenactment events, festivals), safety is our top priority, and we offer several safety features and protocols: 1) Safe demonstration projectiles: We provide soft, lightweight projectiles (foam, lightweight wood, or fabric bags filled with soft material) for public demonstrations, which cannot cause injury or property damage even if they hit someone or something.

We do not recommend using stone or heavy projectiles for public demonstrations. 2) Restricted range: We can adjust the engine’s throwing arm length, counterweight, or puller force to restrict the range for safe demonstration in a limited space, ensuring that projectiles land within a designated safe area.

3) Safety barriers: We recommend installing safety barriers or fencing around the engine and the projectile landing zone, with clear signage and designated spectator areas. We can provide guidance on barrier placement and safety zone sizing. 4) Remote firing mechanism: For added safety, we can install a remote firing mechanism that allows the operator to fire the engine from a safe distance, rather than being near the engine during firing.

5) Crew training: We provide comprehensive training for your crew on safe operation, including loading, firing, maintenance, emergency procedures, and crowd management. We recommend that only trained, certified operators fire the engine during public demonstrations. 6) Emergency stop: We can install an emergency stop mechanism that allows the operator to immediately stop the engine’s motion if necessary.

7) Structural certification: We can provide structural engineering certification for the engine, verifying that it meets modern safety standards for public use. 8) Weather restrictions: We recommend not operating the engine in high winds, rain, or other adverse weather conditions that could affect safety or performance.

9) Insurance: We recommend obtaining appropriate liability insurance for public demonstrations involving functional siege engines, and we can provide documentation to support your insurance application. With these safety features and protocols in place, our full-scale siege engines can be safely operated for public demonstrations, providing a thrilling, educational, and memorable experience for audiences of all ages.

We work with each client to assess the specific safety requirements of their intended use and develop a customized safety plan that meets or exceeds local regulations and industry best practices.

Q: How many people are needed to operate a traction trebuchet, and how do you train them?

A: The number of people needed to operate a traction trebuchet depends on the size of the engine: Small engine (xuanfeng pao): 10-20 pullers, plus 1 loader, 1 commander/operator = 12-22 people total; Medium engine (sijiao pao): 30-50 pullers, plus 2-3 loaders, 1 commander/operator = 33-54 people total;

Large engine (qijiao pao): 80-150 pullers, plus 3-5 loaders, 1 commander/operator = 84-156 people total; Extra-large engine (wodeng pao): 150-250 pullers, plus 5-8 loaders, 1-2 commanders/operators = 156-260 people total. The pullers are the engine’s power source they pull on ropes attached to the short end of the throwing arm to provide the force needed to hurl the projectile.

The pullers need to work in coordination, pulling together on the commander’s signal to provide maximum force and accuracy. The loader(s) place the projectile in the sling and prepare the engine for firing. The commander/operator oversees the operation, gives the signal to fire, and ensures safety.

Training our clients’ crews is an important part of our service, and we provide comprehensive training as part of our installation package: 1) Classroom training: We begin with classroom instruction on the history of the engine, its mechanics and physics, safety procedures, and operational principles.

2) Hands-on training: We then move to hands-on training with the actual engine, starting with basic operations (assembly, loading, aiming) and progressing to full firing practice. 3) Crew coordination: We focus heavily on crew coordination, teaching the pullers how to work together as a team, how to respond to the commander’s signals, and how to pull with maximum force and coordination.

We use practice pulls (without projectiles) to build coordination and strength. 4) Firing practice: We then progress to actual firing practice, starting with light projectiles and short range, and gradually increasing to full-power firing with standard projectiles. We provide feedback and coaching throughout the process to help the crew improve their technique and accuracy.

5) Safety training: We provide comprehensive safety training, including safe operating procedures, emergency procedures, crowd management, weather restrictions, and maintenance safety. 6) Certification: At the end of the training, we evaluate the crew’s competence and provide certification for safe operation if they meet our standards.

7) Training materials: We provide a comprehensive operation manual, safety procedures, training videos, and quick-reference guides for ongoing reference and for training new crew members. The training typically takes 1-3 days depending on the engine size and crew experience. For large engines with big crews, we may recommend additional training sessions to build crew coordination and proficiency.

We also offer follow-up training and refreshers as needed, and we provide ongoing technical support via phone or video call. If you don’t have enough people to operate a large traction trebuchet, we can design a smaller engine that requires fewer pullers, or we can design a counterweight trebuchet that requires only a small crew (3-5 people) to operate (though it fires more slowly).

We can also provide guidance on recruiting and training volunteers for historical reenactment events.

Q: How do I maintain and care for a full-scale siege engine?

A: Proper maintenance is essential to ensure the long life, safety, and authentic appearance of a full-scale siege engine. Here is our recommended maintenance schedule: Daily (during active use): Visual inspection for any loose joints, cracked wood, frayed rope, damaged iron/bronze fittings, or other issues;

check that the throwing arm pivots freely and the axle is properly lubricated; check the sling for any wear or damage; clean the engine of dirt, dust, and debris after use; check the projectiles for any damage. Weekly: More thorough inspection of all structural components including frame, legs, braces, throwing arm, axle, and sling;

check for any signs of rot, insect damage, or structural degradation; check and tighten all rope/rawhide lashings and iron bands; lubricate the axle and pivot points with appropriate lubricant (traditional animal fat or modern grease); check the pulling ropes for any wear or fraying and replace if needed.

Monthly: Detailed inspection of the entire engine including all iron/bronze fittings, nails, bolts, and decorative elements; check for any signs of corrosion on iron/bronze components (surface rust on iron is normal and can be treated, but active corrosion should be addressed); check the paint/oil finish for any chips, cracks, or peeling;

check the throwing arm for any cracks, splits, or bending (especially at the pivot point); check the frame joints for any looseness or movement. Quarterly: Apply wood preservative or oil to any exposed wood surfaces that are showing signs of drying or weathering (for engines kept outdoors or in unheated spaces);

check and replace any worn or damaged rope, rawhide lashings, or sling components (these are wear items and will need periodic replacement); check the iron/bronze fittings and clean/paint as needed to prevent corrosion; check the pulling ropes and replace if worn. Annually: Comprehensive inspection of the entire engine structure including the frame, throwing arm, axle, sling, and all joints;

pressure wash (on low setting) to remove dirt, moss, and biological growth (for outdoor engines); apply a fresh coat of oil, paint, or tar/wax to all wood surfaces as needed; check and re-tighten all frame joints, lashings, and iron bands; check and service the axle and pivot bearings; inspect the iron/bronze fittings and treat any active corrosion;

inspect the sling and replace if worn; document the condition of the engine with photos for future comparison. Every 3-5 years: Major inspection and possible refurbishment including replacing the axle bearings, re-lashing the frame (replacing rope/rawhide lashings), re-finishing the entire engine, checking and reinforcing the structure, replacing the throwing arm if it shows signs of fatigue or cracking, and replacing any severely degraded wood components.

Storage: When not in use, store the engine in a cool, dry, well-ventilated area away from direct sunlight, extreme temperatures, and high humidity. If stored outdoors, use a breathable, waterproof cover (avoid plastic sheeting directly against the wood, as this can trap moisture). Elevate the frame off the ground to prevent rot at the bottom of the legs.

If storing for an extended period, remove the throwing arm if possible to reduce stress on the axle and frame, and store it separately. Loosen and remove the pulling ropes and sling, and store them separately in a dry area. With proper care and maintenance, a well-built full-scale siege engine can last for decades or even generations, providing years of educational value, historical authenticity, and memorable experiences.

We provide a detailed maintenance and care guide with every engine, and we offer maintenance and restoration services for clients who prefer professional care. We also offer maintenance training for your staff, and we can provide replacement parts and maintenance supplies on an ongoing basis. The total annual maintenance cost is typically 2-5% of the initial purchase price, depending on the engine’s use, storage conditions, and environmental exposure.

Q: What is your warranty and after-sales support?

A: We offer a comprehensive 10-year structural warranty for all full-scale ancient Chinese trebuchet and catapult replicas, covering the wooden frame, throwing arm, axle, legs, braces, joinery, and structural components against defects in materials and workmanship under normal use, proper maintenance, and appropriate environmental conditions.

Our traditional joinery and construction is guaranteed for the lifetime of the engine if a joint or structural component fails due to craftsmanship issues, we will repair or replace it at no cost. Iron and bronze fittings are warranted against manufacturing defects for 10 years (normal patina development is not covered;

active corrosion due to improper storage or maintenance is not covered, but we can provide conservation advice and services at cost). The throwing arm is warranted against structural defects for 5 years (normal wear, fatigue, and damage from improper use are not covered, but the throwing arm is designed to be replaceable and we provide replacement arms at cost).

Wheels (if the engine is mobile) are warranted against structural defects for 5 years. Rope, rawhide lashings, and sling components are warranted against manufacturing defects for 1 year (normal wear and weathering not covered, but these are designed to be easily replaceable and we provide replacement parts at cost).

Pulling ropes are warranted for 6 months (normal wear not covered). Projectiles are warranted against manufacturing defects for 1 year (normal wear and damage from use not covered). Finish (paint/oil/tar) is warranted against peeling, cracking, and excessive fading for 3 years under normal indoor conditions (1 year for outdoor conditions, as outdoor exposure naturally causes weathering over time).

Hidden steel core reinforcement (if installed) is warranted for the lifetime of the engine. Modern hidden brakes or safety mechanisms (if installed) are warranted for 5 years. Motorized system (if installed) is warranted for 2 years. We provide lifetime technical support via email, phone, or video call for any questions about assembly, operation, maintenance, repairs, crew training, safety, or historical consultation.

Replacement parts (throwing arm, sling, ropes, lashings, fittings, projectiles, finish, touch-up paint/oil) are available at cost for any component that needs replacement due to wear or damage. We also offer siege engine refurbishment and restoration services if your engine needs cleaning, re-finishing, repair, re-lashing, or complete restoration after years of use, we can restore it to like-new condition.

For commercial clients (museums, theme parks, historical reenactment organizations, production companies), we offer annual maintenance contracts and priority service, including scheduled inspection, maintenance, and repairs by our experienced technicians. We can also provide custom maintenance programs for large siege engine collections or fleets, including regular inspection, cleaning, re-finishing, and part replacement.

We stand behind our products with a commitment to historical accuracy, quality craftsmanship, safety, and customer satisfaction. A well-built and properly maintained full-scale siege engine is an investment that can provide decades of educational value, historical authenticity, and memorable experiences for visitors, audiences, and participants.
