Profile: PDERS Key Lifts Ltd specializes in providing lifts and passenger lifts. EasyLift passenger lift uses a gearless machine combined with flux variable-frequency drive, and closed loop control. The gearless machine affords efficient and quiet operation of the lift whilst providing a smooth, comfortable ride. The closed-loop control system continually communicates the position and speed of the EasyLift car to the controller, which in turn transmits the information to the drive to facilitate adjustment of the lift speed and ride quality. We also provide lift maintenance and repair services.
