Product Description
European type low-noise hoist drive is used in the fully intelligent control operation crane system.
The hoist drive is composed of strengthened aluminum alloy housing,motor, intergrated thermal protection and brake.
The housing of reducer is made of low-pressure cast reinforced aluminum alloy to ensure that the aluminum strength is not deformed and its weight is light. The spline output shaft (European standard) and hard tooth helical gear are made of high-quality 20CrMnTi gear steel. The carburizing treatment ensures the gears' hard teeth surface strength.Then gears are made by CNC precision grinding to ensure the technical requirements of gear hardness and accuracy. The fully enclosed combination hoist drive has a mechanical transmission efficiency up to 98% and a running noise less than 60 dB (A), suitable for outdoor working condition.
The low-noise housing of motor is heat-drawn aluminum alloy, withnheat dissipation and sound-absorbing system. European type rotor skew-slot stator is precisely wound with copper wire, and is deeply dipped in paint. Insulation class F and H, protection class IP55, working system S1 operation, suitable for outdoor working environment +80 ºC to -25 ºC, not suitable for direct corrosive objects. Frequency conversion could reach to 110Hz, start frequency 1Hz.
