AMS Series Electric Chain Hoist Application Case: Helping a Chilean Customer Achieve Safe and Efficient Lifting

Customer: A medium-sized industrial manufacturing company in Chile

Equipment: AMS05-02 (5-ton) electric chain hoist, dual-speed control, lifting height 12 meters

Application Scenario: Heavy component lifting and equipment maintenance in the workshop

Customer Challenges

The customer previously used an electric hoist from an economy brand and faced the following long-term problems:

Frequent overheating shutdowns: High workshop temperatures and dust levels resulted in insufficient motor cooling, causing frequent equipment downtime.

Inaccurate positioning: Single-speed control made precise assembly difficult, leading to low maintenance efficiency.

Safety concerns: Lack of load test certificates and traceable serial numbers resulted in insufficient customer confidence in equipment safety.

Solution

ALLMAN INDUSTRY provided the customer with an AMS series 5-ton electric chain hoist, with the following core configurations:

Working class M5 + Protection class IP55, suitable for dusty and high-temperature workshop environments

Independent cooling fan to ensure the motor does not overheat during long-term operation

Electromagnetic brake + Schneider contactors offer rapid braking response and stable control.

Dual-speed control (4/1 m/min) achieves a balance between rapid lifting and precise positioning.

100% load tested, with test certificates linked to unique serial numbers for full traceability.

Implementation Results: After three months of field use, customer feedback is as follows:

Approximately 30% increase in work efficiency: Dual-speed control and stable heat dissipation make maintenance work more continuous and smooth.

Zero overheating downtime: The AMS series cooling system performs excellently in high-frequency operations.

Enhanced safety confidence: The test certificate and serial number attached to each unit give customers greater peace of mind regarding safety compliance.

“The AMS series has exceeded our expectations. Previously, we had to shut down every few weeks due to motor overheating; now this problem is completely solved. The load test certificate also gives us more confidence in safety management.”

— Maintenance Manager, Chilean Customer

Follow-up Cooperation: Based on the excellent performance of the AMS series, the customer has placed an additional order for two more units of the same model and has included the AMS series in its standard supplier list for equipment procurement.
