In addition, the brake that most of oil pumper adopts is hydraulic braking, and "on" position just works, and just cannot brake transmission system once power-off.
The oil pumper transmission system of above-mentioned citing is rigidity, then hole condition is severe sometimes, will impact when unexpected holddown etc. occur to elevator belt or the transmission system such as wire rope, motor, affects the potential safety hazard that its life-span also exists equipment simultaneously.Certain structures cannot realize putting forward counterweight voluntarily, needs to assist ability by crane, and certain depth reduces practicality.
