What is the TERRA TS500-5 20-Ton Lifting Solution?
The TERRA TS500-5 20-ton stiff boom crane—widely recognized as a heavy-capacity telescopic lorry crane in Southeast Asia, a stiff boom cargo crane in the Middle East and Africa, and a 20t KMU manipulator in Central Asia—is a high-performance lifting solution engineered for large-scale industrial projects. Delivering a massive 510 kN·m rated lifting moment and a maximum lifting height of 23.2 meters, this 20-ton flagship crane bridges the gap between standard truck cranes and heavy mobile cranes. Designed for seamless integration on heavy commercial truck chassis (including 8×4 and heavy 6×4 configurations from HOWO, SHACMAN, ISUZU, and DONGFENG), the TS500-5 occupies a compact 1,200 mm installation space. Fabricated with premium high-tensile structural steel, its 5-section octagonal boom configuration ensures superior structural rigidity and millimeter-level control across infrastructure, mining, oil fields, and heavy logistics.
“For flagship 20-ton industrial lifting, balancing extreme structural leverage with road-legal payload is critical,” states Joseph Lin, Senior Engineering Specialist at TERRA CRANE. “By engineering the TS500-5 with premium high-tensile structural steel and a 5-section octagonal boom, we deliver 510 kN·m of lifting torque while keeping tare weight at 9,800 kg, giving fleet operators maximum legal freight capacity per transport.”
TERRA TS500-5 Engineered High-Performance Advantages
- High-Torque Dual-Pump Hydraulic System: Features a high-pressure dual-pump system ($80+63\\text{ L/min}$ flow rate at $28\\text{ MPa}$) coupled with proportional control valves, ensuring smooth multi-action synchronization for delicate heavy loads.
- Dual Slewing Reducer System: Engineered with twin heavy-duty slewing reducers to deliver smooth, powerful 360-degree continuous slewing rotation under full 510 kN·m tilting moments.
- Elevated Top-Seat Ergonomic Control Station: Equipped with an elevated top-seat control station, offering the operator 360-degree clear visibility over the heavy truck bed and lifting target for maximum jobsite safety.
- High-Strength Wear-Resistant Hydraulic Locks: Cast from high-hardness alloy steel to prevent hydraulic cylinder drift, maintaining unshakeable stability during static suspended lifts.
- Dual-Seal Two-Way Balance Valve: Built with a redundant double-seal internal structure to securely lock the telescoping boom at any working angle, dramatically extending valve service life.
- Bent-Axis Hydraulic Winch System: High-torque bent-axis hydraulic winch delivers fast hoisting speeds and steady cable spooling, complete with an automated over-winding alarm system to prevent wire rope snapping.
- Custom-Built Hydraulic Cylinders: Specifically designed with imported durable oil seals to withstand high friction, ensuring leak-free, powerful boom extension under maximum load.
- Deep-Quenched Slewing Bearing: Deep-hardened raceway design smoothly absorbs severe bending and tilting moments, protecting internal drive gears from wear.
- 4-Layer Steel Wire Reinforced Hoses: Heavy-duty hydraulic lines reinforced with four layers of high-tensile steel wire mesh, resisting temperatures up to 100°C and high working pressures.
- High-Dissipation Thermal Radiator: Large-volume 270L oil reservoir combined with an air-cooled thermal radiator prevents oil thinning in desert climates up to 50°C.

Frequently Asked Questions About 20-Ton Stiff Boom Cranes
Q: What commercial truck chassis configuration is required for the 20-ton TS500-5?
A: Due to its 9,800 kg self-weight and 510 kN·m lifting moment, the TS500-5 must be mounted on a heavy-duty 8×4 chassis or a heavily reinforced 6×4 chassis from commercial truck brands like HOWO, SHACMAN, ISUZU, and DONGFENG. The installation base requires 1,200 mm of mounting space between the cab and cargo body.
Q: What is the main structural advantage of an octagonal boom profile on a 20-ton crane?
A: An octagonal (8-sided) boom geometry distributes high structural loads more evenly across multiple weld seams compared to standard hexagonal or rectangular shapes. This dramatically increases resistance to lateral bending and torsional twisting when lifting heavy loads at long outreach distances up to 22.1 meters.
Q: How does the TS500-5 hydraulic system manage continuous duty in harsh tropical or desert heat?
A: Every TS500-5 is fitted with a 270L high-capacity oil reservoir and a high-efficiency air-cooled hydraulic oil cooler designed to keep fluid temperatures below 60°C in Middle Eastern and African environments up to 50°C. For arctic or sub-zero regions (Central Asia/Russia down to -40°C), specialized low-temperature resistant hydraulic seals are equipped to prevent oil leaks.
