Construction of the lift

This model is specially designed for lifting motor
vehicles. It is electro-hydraulic powered and mainly
composed by two lifting platforms and two auxiliary
lifts and a set of power unit. The gear pump works
when power supply is connected and meanwhile oil in
the pump will push upwards the pistons of oil cylinders.
Thus, scissor arms of the lift rise accordingly.
