Electric Wire Rope Hoist

CD1 and MD type electric wire rope hoist is a light and small lifting equipment, usually installed in the I-beam track (straight or curved), mounted or fixed on the structural frame, used for lifting all kinds of heavy objects. It is often used in conjunction with electric bridge cranes, hoist gantry cranes, and jib cranes. After a simple transformation, it can also be used as a winch. It is widely used in factories, mines, harbors, warehouses, cargo storage areas, and stores.

We offer a wide range of wire rope hoists in various models and tonnages, including CD1 and MD models, low headroom hoists, explosion-proof models, European-style electric hoists, and chain hoists. Common lifting capacities include 2 ton, 3 ton, 5 ton, 10 ton, 12 ton, 15 ton, and 20 ton electric wire rope hoists. For more information or detailed solutions, please feel free to contact our professional team for an accurate quotation and customized service.

CD1 type electric hoist consists of three parts: lifting mechanism, running mechanism, and electric control system.

Lifting mechanism

The hoisting mechanism includes driving, braking, transmission, and a picking-up and winding device. The driving and braking device adopts a squirrel cage conical brake motor, whose rotor, stator, and brake are all conical in structure. MD-type hoist is equipped with a double motor set, which realizes a 1:10 speed ratio through gear reduction. The transmission is a four-stage cylindrical gear reducer, and the pick-up device consists of a hook, a wire rope, and a drum. The overall layout is that the reel is centered, one end is connected to the conical brake motor, and the other end is connected to the gear reducer, connected by a long shaft and rubber coupling. The reel shell is cylindrical and is divided into hanging type and fixed type.

Running mechanism

The running mechanism (hoist trolley) consists of a drive, a brake, a transmission, and a wheel unit. The driving and braking device also adopts a squirrel-cage conical brake motor, and the brake is flat. The drive unit adopts an open and closed cylindrical gear reducer, and the low-speed gears are made up of directly milled teeth from the wheel rims. The wheels are single-rimmed steel wheels with an approximate conical tread. The running trolley is divided into three types: manual, chain, and electric.

Electric control system

The electric control system utilizes two standard magnetic starters to control the hoisting motor (up/down) and the running motor (left/right traverse). The operation is realized by manual push buttons, and the voltage is usually 380V, with some equipment using 36V low voltage for safety. The reel is equipped with a rope guide, which works in conjunction with the hoist limit switch to prevent rope jostling and control the hoist limit position.

The main difference between the CD1 type and MD1 type electric hoist is the hoisting motor and control electrics; the rest of the accessories and components are common. CD1 type electric hoist is single-speed lifting and lowering, which is suitable for general lifting operations; MD1 type electric hoist is double-speed lifting and lowering (normal speed and low speed), which is suitable for precision operations, such as precision loading and unloading, sand box stacking and machine tool maintenance, etc, and the precise operation is realized through low-speed control. The following provides users with product pictures, external dimensions, and detailed parameter tables of the two types of electric hoists.

CD1 Type Electric Hoist Specifications
