Introduction
Electric wire rope hoist is a small light lifting equipment, widely used to lift, loading and unloading, repair equipment, hoisting goods, install on a suspended I-steel, curve track, jib crane rail and fixed lifting hoisting heavy weights.
Electric wire rope hoist can be classified into electric wire rope hoist with electric trolley, electric wire rope hoist with manual trolley, suspended hook electric wire rope hoist ,low headroom electric wire rope hoist.
Advantages
- Efficiency: Electric hoists provide fast and efficient lifting and lowering of loads.
- Precision: MD hoists offer precise control with dual-speed operation, making them suitable for delicate tasks.
- Durability: Built to withstand heavy industrial use with robust construction.
- Safety: Equipped with safety features like overload protection and limit switches.
- Versatility: Suitable for a wide range of applications and can be mounted on various types of cranes and structures.
Application
- Manufacturing: Used for lifting and moving heavy machinery, components, and raw materials.
- Warehousing: Facilitates loading and unloading of goods and materials.
- Construction: Helps in lifting construction materials and equipment to different heights.
- Ship:Utilized for handling ship components, maintenance, and repair.
- Automotive Industry: Used in assembly lines for lifting parts and assemblies.
Electric Wire Rope Hoists Components
Electric Wire Rope Hoists Lifting Motor
Lifting Motor
ZD Conical Rotor Motor/ ZDS Conical Rotor Motor. The ZD 0.8～13KW hoisting motor is a cone-rotor three-phase asynchronous brake motor. The standard motor insulation class is Class B(can reach Class F and H based on the working requirements). The protection grade is IP44/IP54. It has the characteristics of good heat dissipation, long service life, safety and reliability, and can be suitable for long-time work in high-intensity work situations.
Electric Wire Rope Hoists Lifting Reducer
Lifting Reducer
It is the core component of the electric hoist. It adopts a three-stage helical gear transmission mechanism. The gears and gear shafts are made of heat-treated alloy steel, and the bearings are all rolling bearings. The box body and lid are made of high-quality cast iron (grey iron HT200 with good vibration resistance), tightly assembled and well sealed.
Electric Wire Rope Hoists Drum Device
Drum Device
It is mainly composed of shell, drum, intermediate shaft device, rope guide device and limit guide rod device. The shell is rolled by steel plate, and the sleeve is made of high-quality cast iron or steel pipe. A rope guide is installed on the reel . The left and right movement of the rope guide card plate pushes the guide rod device to move, so as to realize the limit stop protection of the electric hoist ascending and descending.
Electric Wire Rope Hoists Hook Group
Hook Group
Forged with high-strength and high-quality carbon steel, such as DG20, with a safety factor > 5. 0.5-5t uses a single pulley hook device, 10t and larger tonnage adopts double pulley type hook device. The hook surface is smooth and no defects such as cracks, folds, and overburn; there are no internal defects such as cracks, white spots, and other inclusions that affect the safety of use. The hook is equipped with an anti-decoupling safety buckle to prevent the wire rope from decoupling and a 360° free rotation facility.
Electric Traversing Trolley
Electric Traversing Trolley
The hoist trolley is composed of a traversing motor, reducer, wall plate, driven an driving wheels, flat nuts, bolts, and adjustment pads. If the lifting height exceeds 9m, 2 trolleys (one active and one driven) are required; for 10t and above, two active trolleys are required. The motor adopts ZDY series cone rotor brake motor or soft start motor.
Electric Wire Rope Hoists Protectiv Device
Protectiv Device
Fire off limit switch, heavy hammer limit switch, overload limiter, pressure loss and phase error protection, etc.
