LADDER MOTOR PUMP SYSTEM
A ladder motor pump system (300) comprises a hydraulic fluid tank (206) that holds hydraulic fluid, a hydraulic pump (304) that draws and pressurizes the hydraulic fluid from the hydraulic fluid tank (206), a one-way electric motor (302) that drives the hydraulic pump (304), a hydraulic ladder actuator (228) that actuates a ladder (102) in first (128, 132, 130) and second (130, 250, 128) patterns, a hydraulic fluid circuit (316) that routes the hydraulic fluid from the hydraulic ladder actuator (228) to the hydraulic fluid tank, and a regulator (222) that routes the pressurized hydraulic fluid from an outlet (312) of the hydraulic pump (304) to the hydraulic fluid tank (206) when a pressure of the pressurized hydraulic fluid exceeds a preselected threshold pressure, mixing the pressurized hydraulic fluid with the unpressurized hydraulic fluid in the hydraulic fluid tank (206) and reducing temperature of the pressurized hydraulic fluid. The electric motor (302) and the pump (304) include bosses providing increased ground connections to the electrical ground (306), thereby reducing electrical resistance and heat generated.
