Product Introduction

Main Features

1.suitable for all kinds of construction project and can work under all kinds of work condition.
2.It has high working speed, good speed-adjusting performance, steady operation and high efficiency.
3.The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment.
4.Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
5.Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.

spare parts

1.Most structure of tower crane are made of angle steel, such as mast string,mast member; the material is Q345B(16Mn).
2. Most components of the tower crane are connected by pins. The pins are produced by special processed combining carburizing, sulfurizing and nitridation. The surface of pins is wear-proof, can be repeatedly assembled and dismantled without deformation.

spare parts

    Trolley mechanisms use torque motor and planetary reducer placed in the drum. Its features include simple structure, small volume, light weight, stable drive, good speed regulation properties, which enables convenient, flexible, safe and reliable operation as well as easy maintenance.

spare parts

   The hoisting mechanism is an AC variable-frequency mechanism, realizing complete stepless speed regulation and fully utilizing motor drive property, featured with wide speed-regulating range and high working efficiency. The mechanical transmission applies mature domestic technique, in which the spur gear or bevel gear work reliably, the rope drum adopts a special Z-shaped grooving technique. The mechanism is equipped with complete and reliable security protection, brake logic control system, capable of realizing “suspension” in the air, and overspeed with light load and largely improving efficiency of tower crane.
