I.                   General introduction

Thanks for your choosing product of Yantai Construction Machinery Factory. For your better understanding of QTZ630 hydraulic auto-lift tower crane, please read this manual carefully.

  QTZ630 tower crane is a hydraulic auto-lift tower machine characteristic of upper-circumgyrating, horizontal arm and variable range with small cabin. The lifting moment is 630KN.m, the independent lifting height is 40m, and with attachments the lifting height can reach 140m. The maximum lifting power is 6t. Two work ranges can be set according to specific requirement: when the work range is 50m, the counterweight is 12t, and when the work range is 45m the counterweight is 11t.

 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, circumgyrating, 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 540? to the left and right. The circumgyrating 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 circumgyrating 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, broad 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 satisfy the need 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 slipforms are used, loading and unloading at port and goods yard.
