Air-operated chain block 0.25TON
<1> High duty ratio, high precision gearbox ● High-strength, low-friction bearings mounted with heat-treated steel and high-precision planetary gears ensure low maintenance, high strength, long lifespan, and high safety of the gearbox. ● A sealed structure that maintains a constantly lubricated state ensures low cost, long operating intervals, and high safety rates for the planetary gearbox. ● By directing the exhaust of the air motor towards the gearbox housing, constant heat dissipation of the gears is ensured, promoting improved gear performance and extended lifespan. <2> Overload limiter Safety is maximized by the overload limiter (standard on YSA-E model) set at the factory to operate at 125% of the rated load. <3> Vane air motor ● High starting torque of the air motor is secured even at low pressure, ensuring a reliable seal between the vane and cylinder surface with compressed air energy from the start. ● Vane made from high-durability, low-friction materials ensures high performance of the hoist, long lifespan of the vanes, and low maintenance of the air motor.

Applications/Examples of results
<4> Automatic Disk Brake When the air supply is interrupted or when there is a failure in the air supply system during operation, the asbestos-free brake activates automatically. <5> Emergency Stop System In accordance with EU directives, when the E-STOP emergency button on the pendant is pressed, air is directed to the air motor's air supply shut-off valve, cutting off the air supply to the air motor. <6> Load Chain High-quality DAT (Grade 80) surface-hardened load chain with high durability and strength. <7> Load Chain Upper and Lower Limit Control ● Chain stoppers are installed at the dead ends that serve as upper and lower limits for the load chain. ● When the chain reaches the dead end that serves as the upper or lower limit, the chain stopper activates the limit control lever, closing the air supply valve and cutting off the air supply, which stops the air motor. <8> Hook Slip bearing with 360-degree rotation and high-strength safety latch.
