In order to improve the quality and safety, EC electric hoist is equipped with mechanical load brake, motor brake and overload clutch as standard accessories. Product features Rated load range from 1 / 4 to 5 tons, lifting height of 3 meters. Other heights are available on request. The length of the standard control handle line is 1.2m shorter than the lifting height. The suspension mode can choose fixed or rotating upper hook, handle, hand push / hand pull trolley and electric trolley. Double brake design. The first group is mechanical load brake, the second group is electromagnetic disc brake. Provide more reliability to control the decline of goods. The long closed spring disc electric brake is adopted. When the control key is released or the power is cut off, the goods can be stopped by the direct action of the spring. Ergonomic handle - strong and corrosion resistant. It conforms to the contour of human hand, and the standard is 24 V control voltage. It also conforms to NEMA 3R (waterproof) standard to ensure the safety of users. It can also provide 115 V voltage. 5-wheel lifting sprocket - better improve the chain fit, so as to run smoothly and reduce wear. Limit switch - adjustable upper and lower limit switch to adjust the cargo travel. Gear transmission mechanism - in EC small hoists, the first spiral gear transmission mechanism is adopted; in EC large hoists, the first and third spiral gear transmission mechanisms are adopted. The transmission gear is made of precision machined alloy steel, which can be operated for a longer time with lower noise after oil immersion. Overload clutch - ensures the safety of users, hoists and supporting structures in case of overload, sliding chain or reverse phase. Small frame design - the shell is cast with aluminum alloy, not only lightweight, but also the motor is up to 1HP. Large frame design - cast iron bearing shell, high strength. The non load bearing shell made of aluminum alloy is light. It can be used for motors with large torque of 2 and 3 HP and 3 phase. Durable construction - in accordance with ASME / ANSI b30.16 and CSA standards.
