The SQS100A-3 represents a highly capable 4-ton telescopic boom truck-mounted crane, meticulously engineered for demanding heavy-lifting tasks across construction sites, industrial facilities, municipal maintenance, and logistics yards. Boasting a formidable 4000kg maximum lifting capacity and a 10t·m rated lifting moment, this hydraulic powerhouse transforms standard commercial vehicles into versatile mobile lifting solutions.
Its ultra-compact 700mm installation footprint ensures optimal space utilization, allowing fleet operators to maximize their payload capacity without sacrificing hoisting power. Built in compliance with rigorous CE and ISO manufacturing standards, every unit undergoes intensive continuous fatigue testing and overload verification before deployment. By balancing exceptional hydraulic precision, 360-degree unrestricted slewing, and remarkably low maintenance demands, the SQS100A-3 empowers procurement teams and project managers to streamline operations, reduce equipment redundancy, and accelerate project timelines in the most challenging environments.
Delivering a formidable 4000kg maximum load threshold and a 10t·m rated lifting moment, this unit easily tackles demanding medium-to-heavy hoisting tasks. Whether lifting dense concrete precasts or heavy structural steel, the crane maintains exceptional stability under stress. By consolidating lifting capabilities into a single mobile unit, project managers can eliminate the need for renting supplementary stationary cranes.
Reduces equipment redundancy on crowded, complex job sites.
Accelerates heavy machinery loading and unloading cycles.
Significantly lowers overall daily project execution costs.
Requiring a mere 700mm of chassis space and weighing just 1350kg, this unit guarantees a non-destructive, straightforward modification process. It offers broad compatibility with mainstream medium-duty global truck chassis platforms, including Isuzu, Dongfeng, and Hino. The standardized Power Take-Off (PTO) interface ensures swift mechanical integration. This ultra-compact footprint preserves the truck's primary cargo bed, allowing fleet operators to maximize effective payload yields while deploying a fully capable mobile crane.
Powered by a highly responsive hydraulic architecture delivering 32 L/min flow at a 20 MPa rated pressure (driven by a recommended 16 kW power source), operators experience the smooth, quiet hum of efficient fluid power. The inclusion of high-precision multi-way valves allows for dual-side linkage operation, providing distinct tactile feedback through the levers. For complex environments, an optional industrial-grade wireless remote control facilitates millimeter-level micro-movements, ensuring delicate loads are positioned with absolute certainty while minimizing operator fatigue.
The unrestricted 360° continuous rotation mechanism empowers operators to handle loads from any angle without constantly repositioning the vehicle. This multidirectional flexibility is a critical asset when navigating tight urban alleyways, enclosed factory floors, or densely packed logistics yards. By significantly cutting down on vehicle maneuvering time, teams can execute more hoisting cycles per shift, directly boosting daily productivity metrics and keeping tight project schedules on track.
Fabricated from high-strength special structural steel utilizing fully automated precision welding techniques, the boom exhibits exceptional anti-bending properties and an extended fatigue life. The exterior is treated with a weather-resistant industrial coating that feels rugged to the touch, effectively repelling moisture, abrasive dust, and corrosive elements found on harsh job sites. This rigorous manufacturing approach guarantees stable, long-term reliability, slashing unplanned maintenance downtime and maximizing the equipment's lifecycle return on investment.

A vital asset for urban infrastructure and mid-sized building sites, this crane excels in hoisting steel beams, concrete modules, and bulk materials. Beyond standard lifting, it supports extensive attachment expansions—including aerial work baskets, log grapples, and earth augers—transforming the truck into a multi-purpose engineering vehicle capable of adapting to diverse foundational and structural tasks while withstanding harsh outdoor elements.
Inside busy manufacturing plants and heavy machinery workshops, the precise hydraulic articulation is crucial. It allows maintenance crews to carefully extract and relocate sensitive production equipment without sudden jolts. The smooth operation minimizes the risk of impact damage to high-value assets, streamlining assembly line reconfigurations and daily material handling within enclosed industrial environments.
For freight hubs and storage yards, agility equals profitability. This vehicle-mounted solution facilitates rapid cross-yard mobility, handling medium-to-heavy cargo loading and stacking with ease. By replacing fixed gantry systems, logistics managers can dynamically route the crane to wherever the bottlenecks are, accelerating cargo turnover rates and optimizing yard storage density without expanding fixed infrastructure.
Utility providers rely on this unit for erecting streetlights, positioning traffic signals, and planting mature trees in urban greening projects. The compact operational radius ensures that municipal crews can perform essential maintenance while occupying minimal lane space, significantly reducing traffic disruptions and enhancing the safety of roadside work zones for both operators and civilians.
Before initiating any lift, operators must park on stable, level terrain and fully engage the parking brake. Visually inspect the work zone for overhead obstructions, particularly maintaining a strict 10-meter clearance from high-voltage power lines. Verify that the intended load falls well within the 4000kg limit and ensure all control levers rest in the neutral position before engaging the PTO to power the hydraulic system.
Deploy the outriggers fully, listening for the solid metallic clunk as they lock securely into place, and utilize support pads on yielding soil to prevent tipping hazards. Operators should manipulate one boom control handle at a time to maintain predictable load trajectories. Elevate loads with deliberate, steady inputs to prevent hazardous swinging, and strictly enforce a clear perimeter, ensuring no personnel walk beneath a suspended object at any time.
Maximizing the crane's operational lifespan requires diligent upkeep. Regularly lubricate all pivot points, boom slide pads, and hydraulic cylinder pins to prevent abrasive wear. Operators must check the 60L oil tank capacity daily, inspect hydraulic hoses for micro-abrasions, and torque any loose structural bolts. All hydraulic servicing must be conducted by certified technicians using original replacement components to guarantee sustained safety.
To comprehensively mitigate operational risks, this unit is factory-equipped with a robust suite of mechanical and hydraulic safeguards. Standard inclusions feature integrated hydraulic locks, balance valves, and anti-drop valves that immediately halt load descent in the event of pressure loss. Furthermore, an intelligent overload alarm system provides real-time auditory warnings, effectively preventing dangerous over-capacity lifts and ensuring absolute site safety.
The SQS100A-3 delivers a maximum lifting capacity of 4000kg (4 tons) alongside a rated lifting moment of 10t·m. This configuration provides the necessary power and stability to safely execute demanding medium-to-heavy lifting operations across construction, industrial, and municipal sectors.
It features an ultra-compact installation footprint requiring only 700mm of chassis space.
