The SQS100A-4 4 ton telescopic boom truck crane is a high-performance, compact hydraulic lifting solution engineered for professional commercial operators and small-to-medium project contractors. Delivering a maximum lifting capacity of 4000 kg and a rated lifting moment of 10 t·m, this hydraulic truck mounted crane balances robust lifting power with a lightweight 1450 kg body and ultra-narrow 700 mm installation footprint, compatible with most medium-duty and light commercial trucks. With full 360° slewing capability and a precision hydraulic system, it delivers safe, efficient, and flexible operation across diverse job sites, from tight urban streets to remote field work zones.
This 4 ton telescopic boom lorry crane is equipped with an advanced hydraulic system (20 MPa rated pressure, 32 L/min flow, 16 kW matched power). Its innovative dual telescopic cylinder design separates boom lifting and extension functions, ensuring smooth, jitter-free movement and precise load positioning, while reducing energy loss and extending component service life.
Fabricated from high-strength steel with precision welding, the boom adopts a reinforced hexagonal-pentagonal structure, delivering exceptional load-bearing capacity and minimal deformation under heavy loads. Corrosion-resistant treatment and heavy-duty pivot components ensure long-term durability in harsh environments, with minimal routine maintenance to cut operational downtime.
With a 700 mm minimal installation space and full 360° continuous slewing, this compact truck mounted telescopic crane excels in narrow work areas. Its optimized structure maintains excellent stability without sacrificing the carrier truck’s payload, making it ideal for urban and municipal projects with limited operating room.

This 4 ton hydraulic lifting crane is a versatile workhorse across professional sectors:
Municipal & Urban Utility Works: Street light installation, traffic signal setup, utility pole maintenance, and urban landscaping in narrow urban spaces.
Construction & Infrastructure Projects: Lifting building materials, steel beams, and prefabricated panels for residential and small commercial construction, plus rural infrastructure upgrades.
Logistics & Warehouse Handling: Medium-heavy cargo loading/unloading in freight yards and distribution centers, improving efficiency and reducing manual labor risks.
Agricultural & Field Maintenance: Farm equipment installation, heavy agricultural material handling, and remote field machinery repair.
Park the truck on firm, level ground, engage the parking brake, and fully extend outriggers with support pads on soft terrain. Inspect hydraulic hoses, boom components, and control levers, and confirm the load is within rated capacity for the current boom radius. Maintain a 10 m minimum distance from overhead high-voltage lines.
Operate only one control handle at a time; never actuate multiple boom functions simultaneously. Lift loads slowly and steadily, avoid sudden movements, and never leave suspended loads unattended. Do not extend the working radius while rotating a loaded boom to prevent tipping.
Lubricate pivot points, boom slides, and hydraulic cylinder pins after each work cycle. Check hydraulic oil levels daily, and inspect hose wear, loose bolts, and structural damage monthly. Only trained personnel may perform hydraulic system maintenance.
The crane weighs 1450 kg, striking an optimal balance between structural strength and lightweight design, enabling easy installation on most medium-duty and light commercial trucks while maximizing the carrier’s payload.
Yes. Its ultra-compact 700 mm footprint and full 360° slewing enable flexible operation in narrow streets and restricted urban job sites, making it a top choice for municipal urban projects.
Absolutely. It is engineered for continuous, repetitive lifting, with a high-strength steel structure and durable hydraulic system that maintains stable performance during long working hours for daily logistics and construction tasks.
We provide comprehensive global support, including original spare parts, installation guidance, operator training, and long-term technical troubleshooting, to reduce maintenance costs and downtime throughout the product lifecycle.
