A system for lifting, handling, and transporting containers includes a trailer that is either connectable to a truck or permanently affixed to a truck. The trailer has front and rear ends and is configured to receive and hold a container. A dolly is mounted on the trailer to lift and handle the container while maintaining the container in an upright orientation. The dolly may travel between the front and rear ends of the trailer and may be rotatable to face left and right sides of the trailer.

System for loading, handling, and transporting containers

A system for lifting, handling, and transporting containers includes a trailer that is either connectable to a truck or permanently affixed to a truck. The trailer has front and rear ends and is configured to receive and hold a container. A dolly is mounted on the trailer to lift and handle the container while maintaining the container in an upright orientation. The dolly travels between the front and rear ends of the trailer.

A trailer having a front and a rear. The trailer includes a frame constructed to receive a bed and a hitch attached to the frame at the front of the trailer. A tube is pivotally connected to the frame between the front and the rear of the trailer. First and second support arms are connected to the tube. Each wheel support arm has an axle and a wheel located at its distal end. The trailer further includes means for rotating the tube. In one embodiment, the trailer has an inclining feature and a shoe for ground engagement. The shoe is located vertically below a central axis of the tube and longitudinally between the wheels and the front of the trailer. In a second embodiment, the trailer has an inclining and elevating feature. In this second embodiment, the hitch is pivotally connected to the front of the trailer and there is provided means for rotating the tube and rotating the hitch relative to one another to elevate, incline, or decline the bed.

Method and apparatus for an adjustable trailer

A vibration generator includes a weight member, a shaft rotatable about an axis of rotation extending longitudinally therethrough and having a mounting area on which the weight member is mounted, and a positioning arm disposed in engagement with the weight member on the shaft and rotatable about the axis of rotation relative to both the shaft and the weight member. The mounting area engages the weight member and prevents movement of the weight member relative to the shaft in a circumferential direction about the axis of rotation but permits movement of the weight member relative to the shaft in a radial direction orthogonal to the axis of rotation and coplanar with the circumferential direction. The weight member also defines an elongate positioning slot and the positioning arm includes an axially extending portion disposed through the positioning slot for slidable movement within the positioning slot during rotation of the positioning member relative to the shaft. The axially extending portion in fact defines a cam surface disposed in engagement with the weight member within the positioning slot. Rotation of the positioning arm relative to both the shaft and the weight member moves the weight member relative to the shaft in a radial direction orthogonal to the axis of rotation thereby altering the moment of inertia of the weight member about the axis of rotation and resulting in a different amplitude of vibration during rotation of the weight member.

Variable amplitude vibration generator for compaction machine

Vibration is generated by the rotation of an eccentric weight attached to a rotor shaft. A relatively high or low amplitude of vibration is produced by varying the radial position of the eccentric weight relative to the centerline of the rotor shaft. A latch, responsive to the direction of rotation of the rotor shaft, and springs control the radial movement of the eccentric weight. Rotation of the rotor shaft in one direction will cause the eccentric weight to be restrained in close proximity to the shaft, producing relatively low vibration amplitude. Rotation in the opposite direction, will cause the eccentric weight to be released; permitting the eccentric weight to move radially from the rotor shaft under the influence of centrifugal force; producing a higher amplitude of vibration. Springs automatically return the eccentric weight to the low amplitude position when the rotor shaft slows.
