The wire rope electric hoist is a small lifting tool commonly used in various industries. The safety issues of wire rope electric hoists are very important. This article summarizes the safety risks of wire rope electric hoists and some factors that lead to risks.

The CE approved electric wire rope hoist for sale in SEVENCRANE is a lifting hoist that is composed of a motor, a reducer, a brake, and finally winds up a lifting rope through a drum or a lifting chain through a sprocket to drive the lifting device up and down. The electric hoist can be installed alone on the I-beam, or it can be installed on electric or manual single-beam, double-beam, cantilever, gantry and other cranes.

According to whether the electric hoist has an operating mechanism and the type of operating mechanism, it is divided into: fixed electric hoist, single-beam trolley-type electric hoist and double-beam trolley-type electric hoist. Electric hoists without operating mechanisms and for fixed use can be divided into two types: support type and suspension type according to different installation methods. The main components of the wire rope electric hoist are: brake, reducer, drum and wire rope.

The SEVENCRANE electric wire rope hoist cost is the main load-bearing component of the wire rope hoist and it is used very frequently. During maintenance, it is necessary to check the strength of the wire rope frequently and add lubricating oil to the wire rope regularly to reduce the friction between the wire rope and objects. In addition, if the steel wire rope reaches the scrap condition, it should be scrapped and replaced with a new one in time. As an important component of the wciągnik elektryczny linowy, the drum is squeezed, bent and torsioned by the wire rope during operation. During routine maintenance, if cracks are found on the reel, it should be scrapped immediately to eliminate potential safety hazards. Secondly, the wear degree of the rope groove of the drum should not exceed 2 mm. If it exceeds, the groove must be re-grooved.

However, the wall thickness of the drum should not be less than 80% of the original wall thickness, and there should be no cracks on the top and bottom of the drum. The reducer needs to be regularly filled and replaced with lubricating oil, otherwise it will not only produce an excessive “buzzing” sound, but also cause excessive wear or damage to the gears or bearings. If the reducer gear is excessively worn or damaged, or the reducer bearing is damaged, it needs to be disassembled, inspected or replaced immediately to eliminate the fault and reduce the noise. Brakes are an important component to ensure work safety. They can prevent heavy objects from falling suddenly and implement parking functions. If there is a problem with the brakes, safety accidents may occur.

Electric hoists are lifting equipment. Due to operating factors, equipment factors and environmental factors, there are major risks such as lifting injuries, object strikes, and falling from high places.
