CD1/MD1 Electric Wire Rope Hoists are specific type of electrically powered hoists which use wire ropes as opposed to the usual steel chain used on standard electric hoists, which are designed for heavy duty lifting applications. CD1/MD1 Electric Wire Rope Hoists mean CD1 Electric Wire Rope Hoists for single speed and MD1 Electric Wire Rope Hoists for dual speed. they utilize wire rope as the lifting medium and powered electrically, which are made up of a rope storage drum, motor(s), gear box and braking system with universal basic but strong configuration. Besides, with advanced technologies, the design of variable frequency control of electric wire rope hoists used to reduce the impact force and realize accurate positioning.

These type of electric wire rope hoists are originally invented by Soviet. Although they have a long history and out fashioned, they are still popular in developing countries because of their low price and high quality. These standard types of electric wire rope hoist (Standard Headroom / Monorail Wire-Rope Hoist) are typically used on single girder overhead crane systems. They come complete with their own incorporated trolley system which sits on the bottom beam/girder flange. Standard headroom hoists are normally utilized where there is no working height restrictions under the beam. This is because the hoist is suspended below the beam and therefore decreases the maximum height of lift of the crane. The fixing eyebolts allow the hoist fixing on a frame as a double girder trolley or in a suspended execution.

Wire rope electric hoists are developed on the basis of CD, MD, We will provide complete maintenance –free full body design less wear and tear components making maintenance more convenient. The driving unit of electric wire rope hoists adopts China's advanced point line meshing gear structure. The overall structure is compact and reasonable and easy to use. With safe and efficient operation, the can meet the requirements of low noise and low environmental protection. Equipped with the intelligent security operation monitoring recorder, such as the "black box" on the aircraft, can record the work status without interruption to prevent non-professional operation.

Configuration with monorail trolleys type (with electric trolley) --The electric wire rope hoist is supplied in suspended execution with the normal headroom trolley or with the articulated one in case the unit has to run on curves, Trolley electric hoist can be installed with most cranes. The trolley is electrically operated. This is due to the fact that the right rope can lift much heavier loads when compared to chain hoists. Also wire ropes will not likely drop the load immediately if overloaded, shock loaded or the rope fails as there are many wires and strands which make up the wire ropes and it is unlikely that they will all break at once, leaving some intact to hold the load until safely lowered. With a chain hoist, if just 1 chain link breaks the lift will fail straight away and the load will fall, that’s Why Choose an electric wire Rope Hoist instead of an electric chain hoist.

Ramhoist supply three main types of wire-rope hoisting systems. Standard headroom monorail hoists, foot/base mounted rope hoist systems and crab units. While trolley electric hoist can be installed with most cranes or hang on the steel girder, hoisting cargo in straight line or curve line; fixed electric hoist can be installed on fixed support and lift cargo with vertically or with different angles, can be widely used to lift heavy objects.

Electric wire rope hoists can be mixed with inflammable and explosive gas operation environment, the lifting speed is constant speed, can satisfy the requirements of the users of some fine work, such as sand and mound precision instruments, such as loading and unloading operation. The electric wire rope hoists can be explosion-proof, firstly because of leakage parts are all made of special materials: no spark, reliable, small volume, light weight, belong to the new type of small and medium-sized lifting equipment, greatly reduce the strength of human labor, realize mechanized hoisting, improve the work efficiency, is the necessary products in many industries today.

Electric wire rope hoists are widely applied for lifting, loading and unloading cargos or trucks in factories, mines, agricultures, electricity, construction sites, workshops, industrials, wharfs, warehouses and other fields. they are typically used in areas where heavy duty lifting equipment is needed such as heavy foundries, large factories and manufacturing plants, and it is also a popular light lifting equipment. They can be mounted on the straight or curve I beam and H beam of Single girder overhead cranes which called stationery mounted (hang on the steel girder, hoisting cargo in straight line or curve line; fixed electric hoist can be installed on fixed support and lift cargo with vertically or with different angles) or be used together with Double-beam, monorail or bridge beam(s), Gantry crane, Slewing cranes, Jib cranes, EOT cranes, Portal cranes, Crane kits by means of a trolley.

Electric wire rope hoists are also called electric traveling wire rope hoists, electric wire hoists, electric cable hoists, mini electric wire rope hoists with remote control, travelling wire hoists, double girder wire rope hoists, portable electric hoists, wire rope electric hoists, CD type wire rope hoists, small hoists, suspension electric wire rope hoists.

      The electric wire rope hoists use helical gear  three stage reducer. Gear and shaft are made by alloy steel and high carbon  steel and through proper heat treatment to ensure its reliability and service life. the reducer is independent, so it’s easy to load and unload it. Box body and cover is made of cast iron to ensure hoist's good damping performance and reliable sealing

3. Rope drum
       Grooved Drum, seamless pipe of adequate length to be wounded in one layer and to provide proper support for the rope to minimize abrasive wear is provided. Drum Shaft resolves on Ball Bearings for ensuring smooth running. Rope Drum is made of cast iron or seamless steel tube, using/with the help of spline transferring power. The selling of rope drum is welded with steel plate. Rope drum is the central heart of a hoist. The upper side is linked with traveling mechanism through equalizing beam. Both ends are connected with lifting brake and motor respectively. The lower side works together with hook through wire rope. Up front of the cover, limiting stopper guide-rod and heavy punch stop block are installed. Rope drum is inside the wire ropes.

4.  Rope guide
       Rope Guide is in two halves, ensuring easy accessibility. It encircles the Drum completely so that the rope may not uncoil even when the electric wire rope Hoist is in unloaded condition. The rope guides of ours is thickened and dilated, so that it is not easy to be damaged.
