The SQS300G-4 12-ton telescopic boom truck-mounted crane is engineered to deliver exceptional lifting muscle, pinpoint operational accuracy, and uncompromising reliability for demanding heavy-duty projects. Whether you are managing complex urban infrastructure upgrades or intensive logistics operations, this equipment provides the mechanical leverage needed to streamline your workflow and enhance site productivity.
Capable of handling up to 12,000 kg with a formidable maximum lifting moment of 30 t·m. The advanced telescopic boom architecture ensures an exceptional working radius and lifting height, allowing operators to effortlessly manage high-rise material placement and long-distance cargo positioning without constantly repositioning the vehicle.
Operating at a recommended flow of 63+40 L/min under 28 MPa rated hydraulic pressure, the system guarantees smooth, jerk-free articulation. This precision is critical when maneuvering heavy, sensitive loads into tight spatial tolerances, minimizing material damage and enhancing overall site safety.
Featuring a continuous 360-degree rotation mechanism, this crane offers maximum directional flexibility in confined industrial environments. To counteract the immense dynamic forces during full-capacity lifts, it is equipped with an ultra-wide hydraulic stabilizer span. This rock-solid foundation anchors the chassis firmly to the ground, preventing tilt and ensuring absolute stability during complex rotational maneuvers.
The entire boom and main load-bearing components are fabricated from heavily reinforced, high-yield structural steel. This meticulous heavy-duty design resists metal fatigue, withstands extreme mechanical stress, and guarantees a prolonged operational lifespan even when subjected to the harsh, corrosive environments of marine ports and heavy industrial plants.
When evaluating heavy lifting equipment, exact specifications dictate operational readiness. The SQS300G-4 is meticulously calibrated to balance raw power with spatial efficiency. With a compact installation space requirement of just 1,300 mm, it leaves ample room on the truck bed for cargo transport. The 200-liter oil tank capacity ensures sustained hydraulic performance during extended shifts without the risk of thermal overload. Every metric, from the 4,300 kg crane weight to the 30 KW recommended power, has been optimized to maximize the payload-to-weight ratio, ensuring your fleet operates at peak mechanical efficiency.

The versatility of the SQS300G-4 makes it an indispensable asset across a multitude of demanding sectors. By integrating heavy lifting and transportation capabilities into a single mobile unit, it dramatically reduces the need for auxiliary handling equipment on-site, saving both time and operational costs.
Construction Sites: Essential for hoisting heavy steel I-beams, positioning massive prefabricated concrete panels, and maneuvering structural components into place with millimeter accuracy. It accelerates building timelines by keeping materials moving efficiently.
Industrial Operations: Perfectly suited for the installation, assembly, or relocation of large-scale manufacturing machinery. The precise hydraulic controls allow operators to gently lower sensitive industrial equipment into exact alignments without jarring impacts.
Port Handling: Thrives in the fast-paced environment of maritime logistics. It expertly handles the loading and unloading of shipping containers, oversized heavy cargo, and bulk industrial materials, ensuring smooth transitions from ship to shore to truck.
Urban Projects: Designed to navigate the spatial constraints of city environments. It is highly effective for installing municipal infrastructure such as towering streetlights, heavy traffic signal gantries, and utility transformers while minimizing disruption to surrounding traffic flows.
A: For optimal safety and performance, we recommend utilizing commercial truck chassis with a payload capacity that comfortably supports the 4,300 kg deadweight of the hydraulic crane, plus your intended maximum cargo load. Proper axle weight distribution is critical, and a minimum installation space of 1,300 mm is required behind the cab.
A: Yes, absolutely. The crane is engineered with reinforced structural steel and a high-capacity 200L hydraulic oil tank to prevent overheating during continuous, high-frequency usage. Its 360-degree continuous slewing capability makes it exceptionally stable and precise for handling industrial cargo in busy maritime environments.
A: To maintain peak operational efficiency at the rated 28 MPa hydraulic pressure, we advise comprehensive oil and filter inspections every 500 working hours. Additionally, routine visual checks of all high-pressure hoses, directional control valves, and the dual-pump system are highly recommended to prevent unexpected downtime.
A: Yes, we possess extensive experience in global logistics, ensuring secure and compliant international shipping for all heavy machinery. Beyond delivery, we supply a comprehensive inventory of readily available spare parts and offer dedicated technical guidance to support your fleet globally.
A: Yes, the system is rigorously tested and rated to handle up to 12,000 kg with a maximum lifting moment of 30 t·m. When the ultra-wide hydraulic stabilizers are fully deployed on solid ground, the crane maintains a secure center of gravity, allowing for safe, stable lifts even at maximum horizontal outreach.
