Introduction

Main Features and Benefits

Safety and Reliability

Our cranes and hoists adopt compact modular maintenance-free design, less easy damaged parts. It provides the user with the best logistics solution to ensure the reliability and safety of equipment operation.

The crane provides with many protection including linkage, overload protection, zero protection and limit protection, ensuring the crane always under safety operation.

The crane provides with advanced PLC automatic detection function, which can perform measurement, calculation and monitoring to the performance, safety and working condition in order to ensure more safe and reliable transportation of items.

Safety Monitoring System

Weihua designs safety monitoring systems for hoisting and travelling mechanism, many functions can be achieved according to the demands of users.

1. Compute the rest circles of safety work of hoisting mechanism.

2. Accumulated working time for hoisting.

3. Accumulated overload times,

4. Accumulated start up times of hoisting motor.

5. Over-heat protection of hoisting motor and alarm.

6. Overload protection and alarm.

7. Brake pad thickness alarm.

8. Display fault information and maintenance tips.

Variable Frequency Drive(VFD)

Variable Frequency Drive(VFD) design is best suite for varied travel speed and the highest positioning accuracy working conditions required, such as high precision machining and assembly workshops and handling the precious dangerous products.

Core technical characteristics.

1. Smooth start and stop brings minimum impact and lower wear of brake, gears etc. Which will extend the system life cycle and reduce maintenance cost.

2. Variable controlled speed reduce load swing.

3. Slow speed for full load ensure safety while fast speed for light load improve efficiency.

4. Energy saving.

5. Low noise.

Smart Electronic Anti-sway Control Technology

The electronic anti-sway control technology can reduce the mechanical and electrical damage caused by load shaking through controlling the sloshing of the load. The crane becomes easy to control, and the loads can be easily and accurately reached the designated position.

The crane operator will concentrate on the load itself, rather than the movement of the crane, the entire transportation process will be safer, accurate and the work efficiency will be greatly improved.

Explosion Proof for Hazardous Environment

Our explosion proof cranes with our wire rope electric hoist developed and manufactured for hazardous working environments complies with IECEx and 94/9/EC ATEX standards and regulations.

The crane is designed and manufactured to meet the special operational requirements for working in an explosive environment with safety and reliability and can be used in explosive atmospheres (gas Zone 1 and Zone 2, dust Zones 21 and 22). The wire rope hoist and open winch has modular design, flexibility and compact in construction, with a hoist rated load from 3,200 kg to 50,000 kg and winch load from 5,000 KGS to 500,000 KGS with standard working duty FEM 2M.
