Description

The Titlis brand QTZ63 tower crane is an up-slewing, horizontal-boom self-elevating tower crane developed by Hongda Group with more than 20 years of tower crane design and production experience. It meets GB/T5031<> and GB5144 "Safety Regulations for Tower Cranes" and other standards. The machine has the following characteristics:

1) Advanced performance parameters, large lifting torque, high lifting height, large working range, wide working space and high use efficiency.

2) The whole machine has beautiful appearance, lightweight steel structure, excellent material selection and pretreatment such as shaping shot peening and rust prevention; the standard section adopts mold assembly welding and cutting processing, which has good interchangeability; the tower top is forward inclined, The force is simple; it is connected by pin shafts and high-strength bolts, which is convenient for assembly and disassembly; the side-mounted cab has a wide field of vision, and the driver's seat can be adjusted freely according to the needs of the human body, and the operation is comfortable.

3) The machine has fixed and attached work types, which can meet the needs of urban high-rise buildings, industrial plants, power station dams, bridges and other construction needs.

4) The hoisting mechanism adopts three-speed motor speed regulation technology, which can obtain the ideal hoisting speed and slow loading of the load. The slewing mechanism adopts frequency conversion stepless speed regulation technology or hydraulic coupling connection, working smoothly. The traction mechanism is driven by a two-speed motor, which is accurate in position.

5) The electronic control system adopts the international general type, and the low-voltage electrical appliances adopt imported electrical components, modular combination, and rail-mounted installation. It is operated by two cross-type master controllers and button switches concentrated in the driver's cab. The whole electrical control cabinet is universal for 380V-440V (50Hz-60Hz) power supply.

6) Various safety devices are complete, equipped with torque, weight, amplitude, and height monitoring functions, as well as alarm and self-locking functions.
