Patent number: 5069471Abstract: A travel and utility trailer combination includes a house trailer with a wheel mounted main frame supporting a main closure or house. The main frame has two spaced-apart side beams rearwardly thereof. An auxiliary trailer is hitched to the main frame to have position between the side beams. Side beam extensions are pivoted to the ends of the side beams to have end portions underlying the axle of the auxiliary trailer. A hydraulic linear motor is provided to raise the side beam extensions to horizontal positions to lift the auxiliary trailer wheels off of the ground for over-the-road travel. Removable positioning pins passing through openings in the side beam extensions and plates integral with the side beams maintain these extensions in horizontal position.Type: GrantFiled: December 26, 1990Date of Patent: December 3, 1991Assignees: James A.

Patent number: 5006031Abstract: A transporting and elevating device (10,12) according to the invention for containers (20) has carrying device (122) attached to the upper part of a two-part carrying frame (30) for the container (20). The parts of the carrying frame (30) may be mutually displaced by internal hydraulic cylinders, which makes it possible for two devices (10,12) according to the invention placed along sides of a transport vehicle to reach up above a container (20) resting on the platform of the vehicle and thereafter pull its lower part upwards to the level of the platform, whereafter carrying device like chains (122) together with braces (126) and push-rods (68) makes it possible to elevate and lower the container.Type: GrantFiled: July 12, 1989Date of Patent: April 9, 1991Assignee: Danish Container Supply ApSInventors: Michael Fossing, Bent T. Jensen

Patent number: 4944646Abstract: A portable self-erecting storage apparatus for asphaltic mix or the like is disclosed, and which comprises a main frame, and three separate wheeled carriages which are mounted in tandem and are concurrently pivotable between a lowered ground engaging position so that the apparatus is highway transportable, and a raised position so that the frame contacts the ground and thus forms the foundation pad for the apparatus during use. The illustrated embodiment includes a secondary frame which supports a storage container, and the secondary frame and the container may be pivoted about an elevated axis between a generally horizontal transport position and a vertical upright or operative position.Type: GrantFiled: January 12, 1989Date of Patent: July 31, 1990Assignee: Astec Industries, Inc.Inventors: M. Earl Edwards, James G. May

Patent number: 4943202Abstract: A tilting mobile platform comprising a platform having an upper surface and a lower surface with a first and a second rail member securely fastened to the lower surface of the platform is disclosed. An axle supporting frame is slidably secured to the rail members. A first axle is rotatably attached to the axle supporting frame such that the axle is transversely mounted on the axle supporting frame relative to a path of movement of the axle supporting frame along the rail members. An axle supporting frame moving means moves the axle supporting frame along the first and the second rail members from a first position to a second position. The axle further includes a first and a second axle arm extending perpendicular to the axle and each axle arm further includes a stud extending substantially perpendicular relative to the axle arm and parallel to the axle. A first and a second ground engaging wheel is rotatably attached to each parallel stud for movably supporting the platform and the articles placed thereon.Type: GrantFiled: March 14, 1988Date of Patent: July 24, 1990Inventor: Donald Galloway

Patent number: 4943200Abstract: A portable self-erecting storage apparatus for asphaltic mix is disclosed and which comprises an elongate material conveying assembly and a separate material storage assembly. The two assemblies are adapted to be separately transported on a highway to the construction site. To effect erection at the construction site, the two assemblies are joined in a nose-to-nose arrangement, and then lifted together in a smooth, continuous lifting operation by a pair of hydraulic jacks mounted on the storage assembly. In the erected position, the container of the storage assembly is vertically oriented and positioned at an elevated location above ground level so as to permit a truck to be driven below the container, and the conveying assembly is inclined upwardly so that its discharge end overlies the top of the container.Type: GrantFiled: January 12, 1989Date of Patent: July 24, 1990Assignee: Astec Industries, Inc.Inventors: M.

Patent number: 4915577Abstract: A self-propelled mobile cradle for boats including a frame having transversely spaced, longitudinally extending side members interconnected at their forward ends to form an opening extending inwardly from the rear end of the frame. Forward driven wheels are used in a caster-like arrangement for supporting the forward end of the frame. Rear wheel are disposed at the rear of the frame for support. The rear wheels comprises at least two wheels each independently operable from the other, one of the wheels being disposed on each side of the frame. Hydraulically operated cylinders are used for raising or lowering the frame relative to the rear wheels. The rear wheels are disposed on independently operable suspension for each of the rear wheels, whereby one side of the frame can be raised or lowered relative to the other side of the frame. A forward driving mechanism is used for raising or lowering the foward end of the frame relative to the wheels.Type: GrantFiled: March 23, 1988Date of Patent: April 10, 1990Inventor: Richard Fraser

Patent number: 4900215Abstract: A dolly for lifting one end of a vehicle and for towing the vehicle includes a pair of identical tandem wheel assemblies interconnected by a pair of spaced parallel steel tubes. At least one of the wheel assemblies includes a hydraulic piston which, in spreading one pair of arms on crank members coupled to the wheel assemblies, forces together the second pair of arms. The ends of the spaced parallel steel tubes are coupled into sockets on the ends of the second pair of arms so that their forcing together operates to lift a vehicle whose tires are resting across the steel tubes. The invention includes means for locking the tubes in their raised position and further includes vehicle wheel locking plates that are actuated by the lifting process.Type: GrantFiled: November 9, 1988Date of Patent: February 13, 1990Inventor: Charles P.
