Lifting capacity 50t electric hoist outline drawing
Product category
Our company mainly manufactures electric hoists with lifting capacity of 0.25~63t, lifting height of 1~100m, working class of M3~M4, also can design and manufacture according to requirements.
Application
Traveling electric hoists can be installed on various kinds of cranes or suspended on I-beam to do some straight or curve motions.Fixed electric hoists can be installed on fixed support to do some vertical motions.Widely used in industrial and mining, rail way, port, warehouse sites.
Working conditions
It is applicable in the temperature of -25℃~+40℃, Humidity≤85%, Altitude below 1000m, Power is 3-phase 380v 50HZ(also can be customized according to customer's requirements)
Structure Layout
Stationary type and operation type both included.
As shown on the right: A1、A2、A3、A4 separately fixed on the up, down, left and right side. A2 always used on the trolley of double beam crane with hoist. It is usually operation type without special explanation, traveling along with beams.

Main Structure and Features
Electric hoist is composed of lifting mechanism, traveling mechanism (except fixed type) and electric parts as shown below:
Lifting Mechanism
Lifting motor drive winding drum rotating through coupling and hollow spindle of reducer, in order to make wire rope of drum drive the hook up and down.
Lifting Motor
- Tapered rotor three-phase asynchronous braking motors
- High starting torque, effective braking, compact structure
- Stable operation, small volume and light weight
- Safety in use, convenient maintain
- B or F class insulation, IP44, IP54 protection
CD1 type hoist fitted with ZD type single speed motor, MD1 type hoist fitted with ZDS type double speed motor, its ratio of usual speed and low speed is 10:1.
Reducer
- Three-level dead axle helical gear rotating body, long service life
- Gear and the axle made by alloy steel after heat treatment, high intensity
- Box and cover made from superior cast iron, fully covered
- Great speed ratio, high accuracy
- Compact structure, silent operation, high efficiency
- Machinery oils
- Easily assemble and disassemble
Rope Drum
- Made of cast iron or seamless steel tube, light weight, transmit the dynamic force by splines.
- Coil casing made from superior cast iron, high intensity
- The drum is the central part of the hoist. It connect with travelling mechanism above through balance beam, with reducer and motor both sides, and with wire rope and hook below. Installed limited guide bar equipment to the up front of the outer cover.
Hook
- Forge with special steel; thrust ball bearing connect with casing through hook and beam to make the hook operate freely.
- No more than 5t :single pulley hook; More than 10t: double pulley hook.
- High security, safety buckle, mousing hook
Travelling Mechanism
Consist of electric trolley, travelling reducer, travelling motor, driven trolley, etc. The mechanism do reciprocating motion through main engine driven by side plate and drum.
The wheel tread is straight when used with box type girder or H beam.
The wheel tread is circular arc when used with I-beam.
Its travelling speed is 20m/min, but 30m/min is possible; if 1~5t capacity with 12m or higher lifting height, a driven trolley is necessary.
Travelling Motor
- Use tapered rotor of three-phase asynchronous braking motors
- Stable starting,safe braking, can be used with reducer
- B grade or F grade of insulation,closed structure,motor protection grade is IP44 or IP54.
Electrical Device
Control box is rational layout,convenient for maintain
The Control box protection grade is IP55, and have water proof
The main power source is optional
Safe touch line has high electrical conduction and low pressure
Current collector has high planing speed, to ensure the sustaining power supply
Consisted with controlling box(0.25t capacity has no it),switch button,stopper and connecting wire
The switch button power voltage is 380v or 36v, standard product is 360v,operating the switch accords to the direction symbols on it,via the disconnector's connect and disconnect(in controlling wire) to control the hoist's moving.
Safe and Standard Protecting Function: no voltage protection,ground protection,short-circuit protection,thermal protection, over-loading protection,limit protection,overcurrent protection,power-off protection
- Lifting limiter:broken fire limit device during up and down travelling
- Overloading protection: overload limiter, according to the working conditions on site to preinstall related parameters
- Top-clashing proof device: heavy punch limiter,sensitive reaction, compact appearance
