Ultra-low headroom electric chain hoist
Structural Composition
Lifting Motor: left-side motor housing, conical rotor motor with built-in brake.
Reduction Mechanism: Hardened helical gear transmission, offering high efficiency and low noise.
Lifting Chain: alloy steel lifting chain, wear-resistant, with a large breaking strength margin.
Double Hook Assembly: two yellow forged hooks on the left and right, both equipped with anti-slip latches, lifting and lowering synchronously .
Chain Guide/Synchronization Mechanism: ensures synchronization of the two hooks and prevents tilting of the workpiece.
Running Trolley: the right-side running mechanism is electrically driven and travels along the I-beam track.
Ultra-low Headroom Body: the body and track are arranged in parallel to minimize the required building height.
Pendant Switch: yellow manual control handle, high protection level, clear button feel.
Safety Devices: bidirectional limit switches, power-off braking, overload protection, and chain anti-derailment.
Working Principle
The lifting motor drives the sprocket through the reducer, lifting and lowering the lifting chain, so that the two hooks rise and fall vertically in sync; the trolley drives the entire machine to move horizontally along the I-beam track. The combination of these two actions completes the entire process of "lifting the workpiece → moving it to the workstation → precisely lowering it." The ultra-low headroom design allows the upper hook limit to be closer to the track, thereby enabling the hook to reach a higher height and a longer effective stroke within the same factory height. The entire process can be completed by one operator using a handheld switch, eliminating the need for a professional crane operator.
Core Advantages
Ultra-low headroom, suitable for low-height plants: the body is arranged close to the track, minimizing the building height occupancy, and greatly increasing the effective lifting height. No need to increase or transform old plants, mezzanine floors, low-height workshops.
Double hooks sync, long pieces without tilting : the two hooks are driven by the same transmission and lift synchronously, solving the problem of tilting and spinning of long strips, plates, molds, and frames with a single hook.
Power distribution trolley design covers the entire working area : the power distribution trolley travels along the track, not only "lifting up and down", but also "delivering left and right", one device, covering the entire workstation line.
Chain structure, compact and durable: alloy steel chain, wear-resistant and impact-resistant, more suitable for frequent, medium and low lifting operations than wire rope.
Complete safety: two-way upper and lower limit switches, to prevent top rush; power failure self-locking brake; overload protection; hook anti-slip tongue, multiple protection.
Easy to operate: pendant centralized control, reasonable button layout, one person can complete all actions; optional remote control, further release the operator's space.
Easy to maintain: modular structure, chains, brakes, limit switches and other wearing parts are standardized, spare parts are readily available, and maintenance downtime is short.
Application Scenarios
Lifting in low-floor/mezzanine workshops; renovation of old plants without height increase; simultaneous lifting of long strips, profiles, and pipes; horizontal lifting of plates, frames, and boxes; mold opening, closing, and turnover; material transfer at assembly line workstations; loading and unloading of CNC machine tools; loading, unloading, and stacking in warehouses; lifting of equipment in maintenance workshops; used with KBK or suspension single-beam systems.
