500 LB Light-Duty Suspended Electric Chain Hoist (250kg Mini Lifting Block)

This 500 LB mini suspended electric chain hoist is specially developed for light-load fixed-point vertical lifting demands, perfectly matching small garages, repair bays, miniature assembly lines and laboratory equipment installation scenarios. Distinguished from medium and large tonnage lifting equipment with bulky dimensions, this mini model adopts miniaturized integrated layout to occupy minimal overhead installation space, ideal for venues with narrow ceiling clearance and low frequent lifting frequency. The whole machine mixes high-strength stamped steel load-bearing frame and die-cast aluminum motor shell, achieving both structural rigidity and ultra-light self-weight, allowing single worker to finish overhead hanging installation without auxiliary lifting tools. The internal circuit adopts simplified modular wiring design, which greatly reduces troubleshooting difficulty during daily maintenance, cutting equipment downtime for small processing plants. Two power supply options are available for global customers: single-phase 220V for household garage power and three-phase 380V for factory industrial power. Equipped with standard wired 3-meter long waterproof pendant with emergency stop button, operators can stand away from the lifting zone to complete operation, effectively avoiding accidental safety risks. It can be stably matched with small cantilever jib cranes, fixed hanging brackets and portable gantry frames for light parts turnover and equipment disassembly work.

Exclusive Mini 500 LB Core Technical Advantages

01 Miniaturized Aluminum Composite Lightweight Housing The motor outer cover and chain storage box adopt high-strength die-cast aluminum alloy, while the main load-bearing bracket uses thickened stamped steel plate. Compared with full steel mini hoists of the same tonnage, the total weight is reduced by nearly 20%. Multi-layer matte anti-rust electrostatic spraying process resists workshop oil mist and dust accumulation, and the integrated heat dissipation rib structure accelerates motor heat emission to avoid overheating under intermittent use.

02 24V Low-Voltage Isolated Safe Control Circuit The whole machine is equipped with independent 24V safety transformer to isolate high-voltage power supply, eliminating electric shock hazards caused by cable aging or damp environment. The IP54 waterproof push-button pendant with prominent red emergency stop button can instantly cut off power once abnormal conditions occur, fully complying with EU small lifting equipment safety standards. Wireless remote control module can be added as customized configuration for unattended remote operation.

03 Dual Redundant Instant Locking Brake System Built-in side-mounted magnetic electromagnetic brake matched with mechanical safety brake forms double locking protection. Once the power supply is cut off accidentally, two sets of brake components act synchronously to clamp the gear shaft tightly and prevent load falling. The non-asbestos wear-resistant brake pad extends service life, reducing frequent disassembly and replacement maintenance work for small factory teams.

04 Case-Hardened G80 Mini Alloy Load Chain Adopts miniature G80 high tensile alloy steel chain after overall quenching treatment, with uniform surface hardness and strong anti-wear performance. Equipped with closed fabric chain bag to neatly store surplus chain during lifting, effectively avoiding chain tangling, scratch and abrasion caused by scattered chain segments. The hot-forged upper and lower hooks are fitted with spring anti-drop safety latches to prevent workpiece unhooking.

05 Complete Multi-Light Load Safety Interlock Devices Integrated mechanical overload slipping clutch will automatically cut off power transmission when exceeding 500 LB rated load to protect motor and gearbox from impact damage. Upper and lower dual magnetic limit switches stop lifting movement immediately to avoid hook collision with the machine body, and anti-phase sequence protection prevents motor reverse rotation caused by wrong wiring connection.

This mini 500 LB suspended chain hoist can operate stably under ambient temperature -20℃ ~ +40℃ and air relative humidity ≤85%, with standard 30% intermittent working duty for light intermittent lifting. Every finished mini hoist passes full-load aging test before delivery, with 12-month global warranty and multilingual online lightweight equipment technical support.
