TrestleJacks R22.5 Workshop unit is a specialized trailer lifting and standing device that utilizes driving motion from the tractor for lifting and lowering heavy load trailer axles. Once in the upright position TrestleJacks becomes an axle support stand with a carrying capacity of 30 Ton.
To perform the procedure, place two 30-Ton R22.5 Workshop units under every axle and put a light foot on the accelerator for the trestlejack to work. The entire process is safe and requires very little effort.
