Nuclear and Power

Introduction

Weihua has been providing thousands of cranes for various types of power plants and power equipment manufacturers. The cranes are widely installed in power plant main room and power equipment manufacturing plant for installation, maintenance and production of power generation equipment. With our complete crane solutions, we have become a trusted partner of power plants around the world.

Nuclear Power Plant Cranes

Weihua nuclear power cranes equipment have covered nuclear island systems and conventional island systems including reactor room cranes, fuel room cranes, steam turbine room cranes, pump room cranes, waste warehouse cranes and other lifting equipment.

Main Features and Benefits

Our nuclear power crane can be remote control. It is designed with single fault protection and multiple redundancy protection. Every drive mechanism has enough Starting torque to ensure safety running in case of one-side bearing Max. wheel load. Enough strength calculation of components and enough protection measures for crane structures. Accurate (±5mm) positioning for trolleys and hoist beam. There is 3d positioning display system for ring rail crane to display the exact position of the hook.

The running of a nuclear power plant needs auto operation inside nuclear plant without people entering in or maintenance for several decades, so choosing safe, reliable and high performed crane equipment is very critical in nuclear plant.

 

Thermal and Hydro Power Plant Cranes

Weihua provides cranes for all kinds of thermal power plants and hydro power plants, our cranes mainly turbine hall cranes, boiler room cranes, dam gantry cranes and maintenance and workshop cranes and hoists.

Main Features and Benefits

1. Saving working space: small limit of left and right space to increase the working space. Small headroom, thus the workshops space can be fully used.

2. Less cost of service and maintenance: reliable performance and durability to reduce extra cost. High quality components need less maintenance and repair. Low energy consumption.

3. Good performance: Frequency conversion tech to lower operating load and make the crane traveling in high speed within light load. Its 1:10 speed range insures the crane traveling smoothly and reduces the impact to workshop. Anti-sway technology to realize precise positioning.

Wind Power Cranes

The self- climbing wind power maintenance crane developed by Weihua will completely change the traditional wind turbine maintenance by large tonnage crawler crane, greatly reduce the maintenance costs and make great contribution to wind power industry.

Main Features and Benefits

1. Self-climbing crane for wind power maintenance consists of four major components: adaptive clamping system, high folding winch lifting system, hydraulic system and electrical control system.

2. Adaptive climbing system is connected by four sets arms device made by special polymer materials with the wind tower, which increases friction at the same time reduces damage to the tower. During working, 4 holding arm legs will work into 2 groups and are driven by telescopic cylinders to achieve climbing.

3. High folding winch lifting system consists of winches, slewing, and luffing telescopic devices, achieving vertical and horizontal movement. The rotary, telescopic luffing make crane in full range of work but also make the whole easy to transport.

4. Two variable hydraulic proportional control systems not only improve the security of the entire hydraulic system, but also reduces the energy consumption of equipment and safety problems, to provide protection for reliable operation of the entire device. Currently, the crane have been declared 4 national utility model patents and 1 national invention.
