GR series of chain hoist from the weight of 1000kg-2900kg, designed for production environments heavy loads, high level work, safe and reliable. The chain hoist particular attention to the choice of materials and the safety and reliability of the test can, aluminum and steel body design, it greatly extended service life, the unique shape design to maximize the space occupied by lower hoist body, to meet the low headroom environment applications. Motor: The motor double winding two-speed motor, a cylindrical rotor, with F insulation class. In accordance with FEM: gourd working-level manufacturing, hoist load 2m sustained rate of 40/15%. Standard working voltage of 380V metal hoist, 3 phase, 50 Hz. Protection class IP55, dustproof, completely prevent intrusion of foreign material, to prevent the intrusion of the liquid jet. Gearbox: through three cylindrical gear reducer mechanism, achieve the specified ratio. Material gear is high-carbon steel, heat treated hardened hoist, effectively ensuring the maximum life. Use proper lubricant, chain electric hoist can be -20 ℃ and + running in the range of 60 ℃. Brake System: DC electromagnetic brakes and a powerful braking capacity, structural stability. Material cast aluminum brakes, ensure proper cooling, brake coil made of epoxy package speed transport hoist, brake discs made of a non-asbestos material. Overload protection: The chain hoist overload protection by friction clutch, friction clutch is a vertical stroke can gourd overload protection safety device, when the load exceeds the rated load, the friction clutch will play a role, to prevent the chain damaged hoist. (Note: This device is a safety device, not as a limit to use, set the clutch according to national standards.) Limit device: the upper and lower electronic limit switches, control dust hoist hook travel to prevent the clutch over heavy use, effectively improve the life of the clutch and gears. All electric chain hoists are in strict accordance with safety standards for electrical equipment installed in the body of the transformer 24V low voltage control. High-quality electronic control components and electromagnetic brakes effectively guarantee the chain hoist to achieve more than 240 times / hour frequent operation.
