Analysis of the hydraulic and electric diagrams

STANDARD LIFTS

DHOLLANDIA tail lifts, a complete range of tail lifts

7

Main objectives• Implement the choice between the lift circuit and tilt circuit

• Analyse and understand the working principles of the standard lift, the most popular in the product range

• Define the differences in electrical wiring and hydraulic circuits between DH-LM with mechanical tilt and DH-LSU with hydraulic tilt at ground level
