Product Description
JMY Air Hoists Trolley Series (0.125~2t)
Product Introduction:
The JMY Air Hoists Trolley Series (0.125–2t) is a versatile and flexible pneumatic lifting solution that combines the safety of air-powered hoisting with the mobility of a trolley-mounted design. With a lifting capacity range of 0.125 to 2 tons (125 kg to 2000 kg), this series is specifically engineered for applications requiring horizontal load movement along overhead tracks, offering extended workspace coverage beyond a single fixed point.
Key Advantages:
*Suitable for complex and hazardous working environments
*Smooth operation with minimal impact; capable of starting under full load
*Infinitely variable speed control for precise positioning
*Overload protection and air-cut (loss of air) protection
*Safe and reliable braking system
*Anti-climbing feature for smooth curved-track travel
*Low failure rate and extended service life
