Product Description

We are Yantai Hanwei Construction Machinery Co.,Ltd. tower crane manufacturers: Tower cranes is a hydraulic self-lifting tower machine characteristic of upper-slewing, horizontal arm and variable range with small cabin. The lifting moment is the independent lifting height is *9m, and with attachment the lifting height can reach **0m. The maximum lifting load is 4t. With scientific design, beautiful appearance, the crane is superior in quality, reasonable in price, safe and reliable in operation, and easy to maintain and repair. It is an ideal construction machine for construction enterprises. The machine has four kinds of work structures: lifting, slewing, variable ranges, and top lifting. The four structures can work in combination as well as independently so as to improve work efficiency. The top lifting structure is used to increase the height of the tower or lower the tower. The lifting structure makes use of multi-speed motor, with three kinds of speeds: quick, intermediate and slow positioning, so as to satisfy different demands. The lifting arm can rotate **0° to the left and right. The slewing and range adjusting are agile and reliable, and the hoisting positioning is accurate. Thus the crane can satisfy the need for vertical and horizontal transportation in construction operation. The machine is equipped with safety facilities such as weight limiter, moment limiter, lifting height limiter, range limiter and slewing limiter, which are sensitive and reliable and can guarantee the normal operation of the machine. Besides, it is ready with rest platform and guardrails. The driver�s room is independently set, beautiful in appearance, board in visual field, with enough inner space and easy to operate. The crane is widely applicable. It can be used in the construction of ordinary civil buildings in small towns and also can be used in the construction of higher civil buildings in middle and large cities. At the same time, it can be applied in the following: building of multi-storey large-span industrial workshops, construction of tower-shape buildings such as high chimneys and silos in which slip forms are used, loading and unloading at port and goods yard.
