A heavy vehicle lifting apparatus and a hydraulic lifting unit. Each lifting unit has a housing with a displaceable upper portion which has an application surface being engageable with a lifting point of the heavy vehicle. Two or more hydraulic actuators are disposed within the housing and linked with a common fixed structure. Each actuator has an extendable cylinder attached to the upper portion. The cylinders in operation collectively vertically displace the upper portion and the application surface between a first position wherein the application surface is disengaged from the lifting point, and a second position wherein the application surface engages the lifting point and the heavy vehicle is lifted from a ground surface.
