The hydraulic unit has a transparent oil tank for easy checking of the oil level. Furthermore, like all electrical components, the power pack has protection class IP65. The entire unit is protected against splashing and dripping water and runs particularly quietly thanks to the suction and return flow filters in the tank. The overflow valve on the oil tank completes the successful hydraulic unit. Depending on the lift table or requirements, the power unit is located either inside or outside the lift table.
