Abstract: A suspension for a trailer vehicle that allows the trailer itself to be used as a ramp. The suspension has an axle having an axis and wheels at each end of the axle. The axle is pivotally connected to the vehicle at a pivotal connection and the axis of the axle is offset from the pivotal connection to the vehicle. An actuation device having a first and second end is pivotally connected to the axle at its first end. The actuation device is movable between a retracted length and extended length. Shifting the actuation device between its retracted and extended lengths causes the axle to pivot about the pivotal connection on the trailer, thereby changing the height of the vehicle relative to the ground surface. The trailer can be used as a ramp, thus, eliminating the need for separate ramps.

Abstract: A handtruck includes a tower having upper and lower ends and a handle adjacent the tower upper end. A support plate is generally adjacent the tower lower end and extends outwardly, the support plate configured to support a load. At least one wheel is operatively coupled to the tower or support plate. The handtruck includes an ejection member for moving the load from the support plate. The ejection member includes an elongate lever having upper and lower ends and being pivotally coupled to the tower. The ejection member includes a pushplate pivotally coupled to the lever and is movable between a rest configuration when the elongate lever upper end is relatively adjacent the tower and an offload configuration when the elongate lever upper end is relatively distant to the tower. A distal end of the pushplate is in slidable contact with the pushplate when moving between rest and offload configurations.

Abstract: A load-bearing trailer dolly which connects a tongue-type boat, utility or other trailer to a towing vehicle and bears weight from the trailer during towing. In a preferred embodiment, the trailer dolly is characterized by an axle mounted on a pair of wheels and an axle mount upward-standing from the axle. A dolly frame height-adjustable on the axle mount by operation of a crank-operated threaded rod includes a forwardly-extending drawbar for attachment to the drawbar receptacle on the towing vehicle and a rearwardly-extending hitch bar fitted with a hitch ball for engaging the trailer tongue on the trailer. A shock-absorbing spring is fitted between the axle mount and the dolly frame for cushioning the dolly frame on the axle mount as the trailer is towed behind the towing vehicle.

Abstract: A forage stack moving device has a tongue and bed mechanism rigidly secured to each other in which a plurality of endless chain elements pass over a plurality of longitudinal beam members and are driven by a mechanism driving all chains in unison while loading and unloading a stack. The bed mechanism is supported by a pair of fourbar linkages, each having a pair of substantially vertically extending arms pivotally joined to a longitudinally extending carriage member to which are secured a pair of wheels, each longitudinally extending member having a hydraulically controlled extensible member connected to the bed mechanism to move the carriage member and the wheels secured thereto, causing the bed mechanism to tilt for loading and unloading and to be substantially level during transportation of any forage stack on the bed mechanism.
