闸轮

When power is transmitted to the elevator shaft, it drives the splined center wheel and the planetary mechanism which consists of three planetary wheels forming 120 degrees with each other and the inner gears drives the drum to rotate, the hoisting band brake is combined with the hoisting disc, and the drum's left ring is combined with the braking band brake, then the elevator has three status: hoisting, braking, and lowering down.

当动力传至升降机轴后，轴带动与花键联接的中心轮，三个互成120度的行心轮及内齿圈组成的行星机构，使卷筒回转，提升抱闸与提升盘结合，卷筒左端外圈与制动抱闸结合，这样升降机具有提升、制动、下降三种工作状态。

Small moment: As the damper plate weight is light, the damper plate and the guide rail and the rubber packing friction drag is small, therefore causes the hand wheel operation moment of force will be small

力矩小：由于闸板重量轻，闸板与导轨及橡胶密封条的摩擦阻力小，故使得手轮操作力矩小
