Energy UNITS FOR DOCK LEVELER 1
Basic Description
This Dock leveler electrical power unit merely raised the ramp when the motor is activated, once the ramp has reached total extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves while the descent. Each the ramp and lip f of each functions 
are controlled by a needle valve. The needle valves are adjustable to realize the wanted descent velocity of each function.
Energy UNITS FOR DOCK LEVELER 2
Standard Description
This Dock leveler electrical power unit simply 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 while the descent. Each the ramp and lip f of each functions are managed by a needle valve. The needle valves are adjustable to achieve the wanted descent speed of each function.
Electrical power UNITS FOR DOCK LEVELER 3
Basic Description
This Dock leveler power unit just raised the ramp once the motor is activated, once the ramp has reached total extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves whilst the descent. Both the ramp and lip f of each functions are controlled by a needle valve. The needle valves are adjustable to achieve the sought after descent speed of every function. The 2nd relief valve assures the main platform to be floating below load when the dock leveler is getting used for loading and unloading the goods, consequently guarding the dock leveler efficiently.
