Landing Gear Operations Landing Gear Operations Installation Semi-trailer landing gear is an important safety component when the prime mover is removed. Furthermore, such gear is subject to high loads while coupling or uncoupling is going on. For that reason, careful installation is required. Prior to installing the landing gear, both legs must be fully retracted thus utilizing full lift after the connecting shaft has been installed and ensuring simultaneous ground contact and uniformly distributed load on both supports. The legs have to be perpendicular and aligned relative to each other to prevent any impeded motion of the connecting shaft through stress. To relieve the screws it is recommended to provide stops above the screw-on plates. A most important aspect is to provide a sufficient propping of the legs in longitudinal as well as lateral direction as shown in Figure 1. The angle between the longitudinal and lateral struts and the leg should be at least 45 and appropriately dimensioned to withstand a shearing force of 3 tons. Operational Instructions Extending the landing gear To operate the landing gear, take crank handle from bracket and engage on shaft. Change into high gear by drawing out crank shaft using crank handle. Extend landing gear to touch the ground. Change to low gear by pushing in crankshaft using crank handle. Raise semi-trailer body to desired height. Retracting the landing gear To connect trailer to prime mover, operate landing gear in reverse order. Maintenance The gear boxes of the landing gears are already filled with grease at delivery and should therefore only be lubricated if handle becomes difficult to turn, using the grease nipples provided. WARNING Prior to painting, cover up or retract inner tube. Page 3 of 5
