Power UNITS FOR DOCK LEVELER 1
Standard Description
This Dock leveler electrical power unit merely raised the ramp when the motor is activated, once the ramp has reached full extension the sequence shifts to lengthen the lip. The ramp and lip are lowered by separate solenoid valves whilst the descent. The two the ramp and lip f of each functions are managed by a needle valve. The needle valves are adjustable to achieve the desired descent speed of each function.
Energy UNITS FOR DOCK LEVELER two
Basic Description
This Dock leveler energy unit just raised the ramp once the motor is activated, once the ramp has reached full extension the sequence shifts to lengthen the lip. The ramp and lip are lowered by separate solenoid valves while the descent. Both the ramp and lip f of each functions are controlled by a needle valve. The needle valves are adjustable to attain the wanted descent speed of each function.
Energy UNITS FOR DOCK LEVELER three
General Description
This Dock leveler energy unit basically raised the ramp once the motor is activated, once the ramp has reached full extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves even though the descent. The two the ramp and lip f of each 
functions are controlled by a needle valve. The needle valves are adjustable to accomplish the sought after descent velocity of each function. The 2nd relief valve ensures the main platform to become floating under load when the dock leveler is being used for loading and unloading the items, thus protecting the dock leveler efficiently.
