Guarantee of Fault Rate for Shandong Dongyue Tower Crane

Shandong Dongyue Lifting Fire Fighting Equipment Manufacturing Co., LTD adheres to the service tenet of "everything for customers" and has established a technical service station and accessory supply center. The products in construction include QTZ50, 63, 80, 160 tower cranes and SC200/200 construction elevators, suitable for various construction fields.

Strict control of supporting components is a prerequisite to ensure that the tower crane is fault-free. Shandong Dongyue Tower Crane adopts high-quality accessories and strict inspection to ensure the safety of tower crane operation to the greatest extent possible.

1. Electrical organization

Shandong Dongyue Tower Crane adopts French Schneider contactors, with complete protection for phase failure and phase sequence, as well as motor overload protection, to ensure the safe and normal operation of the electrical system.

2. Lifting mechanism

The brake wheels are made of cast steel material, with surface quenching treatment, cylindrical grinding processing, and strict control of their runout. Dynamic balance tests are carried out, and each lifting mechanism is subjected to no-load, static, and dynamic load tests to ensure reliable, safe, and durable braking. 

3. Luffing mechanism

The luffing adopts a maintenance-free planetary reducer and motor cone brake, with a reasonable and compact structure. The sports car is stable and powerful, and has high durability.

4. Rotary mechanism

The Shandong Dongyue rotary motor adopts a wound motor with hydraulic transmission, ensuring smooth and powerful rotation.

5. Control device

The cab control device adopts a humanized design to ensure comfort and facilitate safe driving.

Since the development of Shandong Dongyue Tower Crane, the quality of tower crane equipment has been evident to all. With the development of technology, tower crane equipment is also assembled with advanced accessories, striving to maximize the safety of tower crane operation, reduce property losses, and ensure personnel safety.
