Abstract: A trailer landing gear lifting apparatus (100) for raising and lowering landing gear (10) of a trailer (30) has a motor (136) fitted to a motor plate (134) which is affixed to a modified conventional gear housing cover (130) of a trailer landing gear assembly (10). The motor (136) has a motor gear (154) affixed to a motor shaft (156) by a roll pin (158). The motor gear (154) engages a drive low gear (142) of a generally conventional gear system (136). A spacer on a drive shaft 138 locks the gear system (136) such that the drive low gear (142) engages a driven low gear (146). A key switch (172) controls a pair of solenoids (170) to selectively provide power to the motor (136) for raising and lowering the legs (14) of the landing gear assembly (10).
Abstract: A trailer landing gear lifting apparatus (100) for raising and lowering landing gear (10) of a trailer (30) has a wrench (102) connected by an air hose (102, 222) to an air supply line ((212) and, optionally, to an air tank (210). An attachment bracket (104), a keeper arm (106) and a wrench bracket (110) optionally secure the wrench (102) to a pair of I beams (112) of the trailer (30) such that the wrench (102) is affixed to the trailer (30).
