3 ton tower crane

2.Having exported for more than 70 countries 4.Having more than 11 factories 6.Annual produce capacity up to 1000 sets

With Hydraulic Self-raising Mechanism,

With Various Safety Devices

II. Outstanding Features

1. The tower crane is a combination of advanced technologies of the present day. It is equipped with a hydraulic self-raising mechanismand afrequency-converting slewing mechanism.

2. The electric control system of the tower crane adopts the advanced “PLC + frequency converter” control mode of the present day, which has realized the stepless speed regulation and greatly improves the reliability, maneuverability and stability of the control system and the work efficiency of the tower crane.

3. The tower crane is equipped with all kinds of reliable safety devices, such as hoisting height limiter, slewing range limiter and multifunctional limiter to control the load moment, hoisting capacity and trolley traveling range. Its PLC (Programmable Logic Controller) unit can diagnose the cause of breakdowns.

4. The use of world-famous electric components such as OMRON, YASKAWA, Schneider (TE) and MEAN WELL greatly reduces the failure rate of the electric control system and improves the work efficiency of the users.

5. Besides, there are also electric safety devices like anemoscopes and obstacle lights and mechanical safety devices to prevent the breaking of trolley axles and wire ropes.

1 Hoisting Mechanism
Three-gear speed modulation by electrical motor or frequency conversion, giant winch.

2 Rotation Mechanism
Speed modulation with frequency conversion, stable break, accurate position, outstanding on performance and operation all around the world.

3 Luffing Mechanism
Speed modulation with frequency conversion, less concussion, stable operation.

4 Control System
PLC control, auto diagnosis on electric malfunction, corresponding alarm on light and sound, key components adopting international top brand product.

5 Security & Protection Mechanism
Besides security mechanism usually used in domestic tower crane adopted, Hongda tower crane adopted lots of advanced mechanism self-developed by Hongda, to keep the security of the tower crane and convenient operation, such as unique double tighten mechanism on luffing steel cable, anti-break mechanism on sliding vehicle, anti-drop

mechanism on standard section, speedy link between rotary body, hoisting boom and balance boom.

6 Structure
Through advenced design, mechanical-electrical integration design, CAD supporting design, optimization design, modularization design, makes Hongda tower crane's steel structure haveing outstanding intensity, firmness and anti-fatigue capability, outstanding performance and reliability. With beautiful profile, it embodies the design standard of Hongda.
