Sany SQH400

The Sany SQH400 crawler crane boasts a commanding 400 t⋅m ramming capability, coupled with a substantial allowable ramming weight of up to 20 tons, which exemplifies its capacity for heavy-duty operations. Its adaptable boom extends from a modest 12.5 meters to a considerable length of 24.5 meters, facilitating the execution of a wide array of tasks with varying spatial demands. The crane’s design enables it to reach up to a height of 25.9 meters, allowing for significant vertical access, and can work within a radius of 4.7 to 22 meters to accommodate diverse site conditions.

The crane’s speed parameters include a variable winch rope speed of up to 130 m/min and a hoisting rated single rope force of 11 tons, reflecting its swift and powerful lifting potential. Additionally, it can rotate at speeds of up to 2.1 rpm and can travel at speeds reaching 1.37 km/h, providing efficient maneuverability across the worksite. The SQH400’s 30% gradeability underscores its ability to tackle challenging terrains.

At the heart of this machine is the robust WP10.240 engine, delivering a potent 175 kW output at 1900 rpm, ensuring reliable and forceful performance throughout operations. The crane has an overall weight of 64 tons when equipped with an 18.5-meter boom and a 25-ton hook, indicating its substantial construction. It carries a counterweight of 18 tons and has a maximum single-piece transport weight of 40 tons without disassembling the tracks, showcasing its ease of transport and setup. The crane’s transport dimensions (without the lower boom section) are 8200 mm in length, 3300 mm in width, and 3350 mm in height, which, together with a ground contact pressure of 0.072 MPa, illustrates its engineered balance between heavy-lifting capacity and transportability.

The SQH400 is a versatile and efficient solution for a range of lifting tasks, particularly in large-scale construction and infrastructure projects.
