Abstract: A portable pipe irrigation system that is used primarily for temporary drip and sprinkler installations includes a unique trailer that comprises a platform which simplifies installation and removal of the irrigation system. The trailer is either self propelled or pulled by a tractor. A magazine in the central portion of the trailer is of a sufficient length to accommodate pipe of various lengths and cross sections. A work platform is located at either end of the magazine, allowing workers to manipulate the pipe in the magazine and load the pipe into one of two installation chutes. Catwalks are located on one or both sides of the magazine. Two chutes or channels are located on the platform at a comfortable work level. A primary chute is located closest to the magazine and is fitted with a fixed stop on the front end and a pushing lever on the rear end. A secondary chute is provided for final assembly of the pipe sections.

Abstract: An apparatus for easily loading and unloading a motorcycle or similar vehicle onto and from the bed of a utility vehicle such as a pick-up truck which only requires a single operator. The apparatus comprises a guide rail subassembly secured to the bed of a utility vehicle, a main ramp subassembly detachably secured to the guide rail subassembly, a dolly subassembly which is adapted to support the motorcycle and ride on the main ramp subassembly and the guide rail subassembly, a plurality of adjustable tie down straps for detachably securing the motorcycle to the dolly subassembly, and an approach ramp subassembly which is detachably secured to the dolly subassembly. The dolly subassembly has a winch and a battery mounted thereon with the battery powering the winch which has one end of a flexible cable secured thereto and a free end of the flexible cable having a hook secured thereto which is adapted to be attached to an eye bolt secured to the guide rail subassembly.

Abstract: A baggage slide attached to a movable elevated passenger walkway/bridge.

Abstract: A service cart transportable in a van or truck is comprised of a vertically oriented pyramid-shaped profile. The pyramid shape offers a high degree of stability, making it virtually impossible to tip over during normal operating conditions, especially during transport. The cart has a four-wheel base. One set of wheels is preferably swivel casters for turning sharp corners. A second set of wheels is larger and located externally of the cart. These wheels increase the base of the pyramid profile and add to the cart's stability. The service cart may be transported to and from a job site. The cart fits into a van or truck bed. To remove the cart from the vehicle, a ramp system is provided. A mechanical or electrical winch may be used to transport the cart into or out of the vehicle.

Abstract: A dredge having substantially a box-like shape, with an open front face and an open rear face, the rear face having a door hinged thereto and a lock member to hold the door in a locked position. An A-shaped frame member is pivotally secured to the front end of the dredge. Pivotable motion of the A-frame raises the front edge of the dredge over an obstruction. A pulley assembly is secured to the rear top end of the dredge, and a cable from the A-frame is placed over the pulley when the A-frame is to be pivoted to raise the dredge. A door is hinged to the rear side of the dredge. A locking hinge is secured to the rear of the dredge to lock the door in a closed position. The locking hinge includes a pivoting edge, which engages the top edge of the door, and a rectangular bar secured under the locking hinge. The rectangular bar has a width greater than the height so that rotation of the bar produces a pivoting motion of the locking hinge to unlock the door.

Abstract: A portable anchor device for resisting the reaction forces associated with conveyance of a load between horizontal surfaces with different elevations includes at least one beam member with at least one support member pivotably attached at its upper end. The pivotal angle is selectively fixed so that the support member lies flat on the upper surface. A part or all of the load weight is supported on the anchor device and motive force is applied to the load by a winch secured to either the load or the anchor device. An anchor bar near the upper end of the anchor device projects above and behind the proximal edge of the upper surface. The anchor bar is pivotable to maintain collinearity between motive force and load advance. A flexible line which transmits the motive force from the winch to the load is anchored at the distal end of the anchor bar. A safety gate is disposed to prevent load descent until the flexible line is taut.

Abstract: A transport apparatus that can load and unload load carrying containers directly to and from the ground, to and from specially designed receivers or from and to portable support stands. The transport apparatus includes a tiltable trailer having longitudinal guide rails or surfaces that receive anti-friction devices of the load carrying containers. The tiltable trailer can be carried by a ground wheel support chassis and can be pivoted between a substantially horizontal travelling position and a backwardly-downwardly inclined position at which the rear portions of its longitudinal guide surfaces have been displaced toward the ground to a position above the ground where they can engage the anti-friction devices of a ground supported load carrying container.

Abstract: In a climbing four-wheel dolly for moving a load from one elevation to another, a pair of box-channel tracks form a ramp in which sliding door track rollers, mounted on the axle support adjacent the respective dolly wheel channel track, guidingly support the dolly. The dolly is moved up or down the tracks by a winch and pulley arrangement having a cable connected with a tongue at one end of the dolly.

Abstract: The present invention relates to system for suspending a skid pan from a winch mounted on a tractor. The skid pan 2 is pivotably suspended from the winch frame 1 by a bolt 3. Stoppers 5 are fastened to the winch frame 1 in order to prevent the skid pan from swinging forward in the normal driving direction of the tractor. The skid pan can be locked in vertical position by a second bolts 4 which can be put into corresponding holes 6 in the skid pan 2 and the which frame 1.

Abstract: A boathouse loading device for loading a boat out of a body of water and into a boathouse, using in part the motive power of the boat. The device includes a pivotable, slidable carriage for receiving the hull of a boat, outriggers for stabilizing the boat during its movement, a tensionable latching mechanism for initially inhibiting movement of the carriage and a winch for sliding the carriage and for tensioning the latching mechanism.

Abstract: Hoist mechanism for a truck vehicle of the type having a pivotally movable load support frame. Opposed piston hydraulic cylinders are carried by the load support frame. Each of the hydraulic cylinders has a piston rod to which is attached a rotatable sheave. Another sheave is rotatably attched to the load support frame. A cable has one end thereof attached to the load support frame. The cable has portions in engagement with the sheaves and has a free end adapted to be attached to a load. A load is thus drawn upon the load support frame as the hydraulic cylinders are operated.

Abstract: In accordance with illustrative embodiments of the present invention, a new and improved log skidder comprises a motorized vehicle, log carrier means pivotally attached at a point directly above the rear wheels thereof, first means such as a winch for pulling a log toward said carrier means and disposing portions of the log and the carrier means in overlapping relation, and second means such as a winch or a grapple for securing said overlapping portions together as a substantially rigid assembly, whereby the weight of the forward portion of the log is supported directly above the rear wheels of said vehicle.

Abstract: A load handling device for drawing a load up an inclined plane onto a pallet. The device comprises a winch arrangement mounted on a wheeled cart. The cart is provided with a pallet engaging member to be positioned against the side of the pallet which is opposite to the inclined plane.
