A powered landing gear mounted to a trailer includes an electrical connector mounted to the trailer that is configured to receive a jumper cable connected to a truck for supplying electrical power to the trailer, with a wiring harness mounted to the trailer that is electrically coupled to the connector. A landing gear includes a housing member, a telescoping leg member, a gear assembly configured to extend and retract the leg member relative to the housing member, and a drive system including a drive motor operatively engaged with the gear assembly, with the landing gear being operatively powered by electricity provided through the connector and wiring harness from the truck. The wiring harness may be operatively electrically coupled to the drive motor and/or a rechargeable power supply that is in turn electrically coupled to the drive motor, including through a controller.

Electrically coupled powered landing gear

A powered landing gear includes a housing member and a telescoping leg member connected with the housing member, an internal gear assembly located within the housing member is configured to extend and retract the leg member. A shaft extends into the housing member and is connected with the internal gear assembly, where the internal gear assembly includes a ring gear arranged to rotate about an axis that is transverse to the telescopic orientation of the leg member with the internal gear assembly configured to operate in a high speed setting and a low speed setting, and with the internal gear assembly automatically shifting from the high speed setting to the low speed setting. A drive system is attached to the housing member and includes a drive motor and a drive gear, with the drive motor configured to operatively drive the shaft via the drive gear.

Mounting bracket

A carrier assembly for a fifth wheel mounted on a semi-trailer tractor includes a pair of generally parallel spaced rail assemblies, each comprising a bed plate, a rack of teeth superimposed over the bed plate and a rack cover plate superimposed over the rack of teeth. Bolts extend through the rack cover plate, rack of teeth and bed plate. A slider assembly includes a pair of spaced generally parallel axial elements superimposed over respective bed plates and connected by a transverse element. The slider assembly supports a tooth engaging mechanism that selectively engages the rack of teeth and is spring biased and mechanically biased toward a locked position. Rear stops are removably attached to the carrier assembly. Projections on the bed plate and rack cover plate extend into apertures in the rack of teeth to resist shear forces.

Carrier assembly for a fifth wheel

A landing gear crank handle for raising and lowering vehicle landing gear is provided that includes a first hand hold that is horizontal when the handle is in a full extended position, a second hand hold connected to the first hand hold by a central portion, and an arm connected to the first hand hold; and a jaw connector attached to the arm and adapted to connect the crank handle to a landing gear crank mechanism and adapted to allow the crank handle to lock into a collapsed position, a partially extended position, and a full extended position.
