- Mechanical redundancy designed to hold the load in the event of one of the ropes breaking.
Rope Guide
Lightweight Good wear resistance Prevent wire rope from skipping and loosing to off-groove
Lifting Gear Limit Switch
Use seamless steel tube as raw material and process it by numbers of working procedure.
Advanced processing methods to ensure concentricity of the drum.
The depth of rope groove is in compliance with the FEM standard.
High-strength pressing plates and bolts are fastened on the end of the wire rope to ensure the safety of lifting.
Drum
Use seamless steel tube as raw material and process it by numbers of working procedure.
Advanced processing methods to ensure concentricity of the drum.
The depth of rope groove is in compliance with the FEM standard.
High-strength pressing plates and bolts are fastened on the end of the wire rope to ensure the safety of lifting.
Trolley Drive Dnit
Motors include F class insulation and IP55 degree of protection as standard with a special inverter insulation. This motor's ED is 40%.
Electrical System
The easy- to- service control system has the multiple safety protection devices to ensure equipment safe. IP54 protective grade. Quick connector reduces installation and maintenance work to minimum.
Monitoring Unit
The electrical cubicle on the hoist may contain the condition monitoring unit that supervises the safe operation of the hoist. The unit collects data on functions that affects safety and calculates the remaining time in the Safe Working Period (SWP) during which the hoist can operate safely. It has the practical and friendly human-machine interface and easy operation
Lifting Drive Unit
Double winding asynchronous motors, aluminum round frame 60 % duty factor and tropicalized as a standard for greater longevity. IP55 protection, F class Insulation, B class heating, with over temperature protection Electromagnetic brake, maintenance free In normal use the brake lining has been designed for the hoist life. Easy access to the air-gap measuring The hoisting gearbox comprises multistage gear transmission. Lightweight gear units with silent running and hard tooth-surface gears deliver the torque required
Hook Block
Concise and sturdy hook block has the outstanding features of DIN standard: protective hook shield, machined pulley and high-strength material of T-grade load hook.
Wire Rope
Wire rope of high-performance with tensile strength up to 2160MPa. The surface with galvanized processing for corrosion prevention effectively. With good flexibility to ensure wear resistance of the wire rope and prolong its service life.
Electric hoists are beneficial to professionals such as construction workers, machine operators, and mechanics, as well as DIY enthusiasts who work on large-scale projects. Their use cases are so vast that they can be used for lifting and moving heavy machinery and raising and lowering scaffolding in addition to loading and unloading heavy materials from trucks or warehouses.
The leading technique and excellent performance can bring us an optimal limit size and equipment height. In the same working area, RWH electric wire rope hoist can cover a larger operating area, improve the utilization rate of plant space and reduce the blind area.
The Style crane with RWH electric hoist can effectively reduce the weight of the equipment to lower power comsumption, and the running noise is lower than the national standard. Hence it is known as an equipment with comfort of operation, economical cost, and low energy consumption.
