Single-speed wire rope electric hoist
Structural composition
Lifting motor :Conical rotor brake motor, self-locking when power is off, smooth start-up, and large braking torque .
Speed reduction mechanism :hardened helical gear transmission, which is highly efficient, low in noise, and has a long service life .
Drum :The central drum is arranged horizontally, with multiple layers of wire rope wound in a neat arrangement .
Wire rope :Special wire rope for lifting, with tensile strength, wear resistance, and high safety factor .
Pulley hook assembly :yellow hook block + black forged hook and anti-detachment latch .
Fuselage :Green metal shell, compact structure, good protection .
Electrical control box :The blue electrical box on the right integrates contactors and protection components .
Wiring :Red power/control cables, neatly routed out .
Flashlight switch :Yellow handheld button box, high protection level, clear button layout .
Safety devices :upper and lower bidirectional limit switches, power failure brake, hook anti-detachment device, warning signs, and nameplate .
Working principle
The hoisting motor drives the drum to wind and unwind the wire rope via a reducer. The wire rope then drives the hook assembly via pulleys to raise and lower the hook vertically—operating at a single speed throughout the entire process, with a simple and intuitive operating logic. If equipped with an electric trolley, the entire machine can travel horizontally along the I-beam track, forming a complete "lifting + traversing" lifting capability. Operation is completed by a single worker using a handheld flashlight; if the operator needs to be away from the heavy object or work across areas, a wireless remote control can be selected.
Core advantages
Simple structure and few failure points:The single-speed transmission chain is short and there are few parts. Routine maintenance only requires checking the wire rope, brake and limit switch. The maintenance threshold is low and the downtime is short.
Rugged and durable:The classic combination of conical brake motor, hardened gear reducer, and high-quality steel wire rope has been proven in the market for a long time and is suitable for high-frequency continuous operation.
Economical and practical: Compared to the dual-speed model, the procurement cost is lower, making it suitable for budget-sensitive or large-volume projects.
High lifting height:The wire rope winch structure allows for a lifting height far exceeding the conventional upper limit of chain hoists, making it suitable for high-rise buildings, deep foundation pits, and other working conditions.
Safety features include:bidirectional upper and lower limit switches to prevent top impact, a conical brake motor with power-off self-locking, a hook anti-detachment latch, and complete warning signs.
Easy to operate:The flashlight is centrally controlled, allowing a single person to complete all actions; the button layout is clear, making it easy for beginners to learn.
High versatility: It can be used independently for beam hanging, or it can be matched with electric single beam, suspended crane, European crane, KBK system, cantilever crane, one machine for multiple scenarios.
Application scenarios
Machine tool loading and unloading; hoisting of parts, blanks, and semi-finished products; material transfer at assembly line workstations; warehousing loading, unloading, and stacking; hoisting of steel/profiles/pipes; transfer of bulk materials and packages; equipment hoisting in repair workshops; pump, valve, motor, and reducer manufacturing; building materials, hardware, and auto parts processing workshops; use with electric single-girder cranes, overhead cranes, European-style cranes, KBK systems, and cantilever cranes.
