Abstract: A truck and hook hoist combination for picking up and manipulating a container having a grasping ring includes a vehicle having a frame with a rear; a hook hoist including a hoist frame with a rear, a roller frame having a rear and being connected to and at the rear of the hoist frame, and a jib assembly having inboard and outboard ends and being pivotally connected about an axis to the hoist frame, the roller frame including at least one roller rotatably mounted to the rear of the frame and being configured for variable slidable longitudinal extension relative to the rear of the hoist frame prior to the roller frame being rigidly connected to the hoist frame, and wherein the jib assembly includes a hook at its outboard end, the hook defining a base with a front and a rear, a post extending up from the front of the base and a main arcuate hook body extending up from the rear of the base, wherein the base, post and hook body together define a saddle sized to engage with and receive a container grasping ring th

Abstract: A waste compactor apparatus having a front, a back and sides, includes a compactor adapted to receive waste materials through an opening in the front and to compress the waste materials into a waste container positioned therebelow; a waste container defining an upwardly facing opening; a support frame supporting the compactor above a channel defined by the support frame, the channel sized for receiving the waste container in a position substantially subjacent the compactor; and, a stop header adapted for variable attachment to the support frame for defining the direction from which the container may be inserted and withdrawn from the channel of the frame.

Abstract: A waste handling container includes a container body with a top and an opening defined therein, the opening having opposite sides; a lid adapted to cover and seal shut the opening; and, a lid control assembly for supporting and guiding the lid and enabling the lid to be moved between a horizontal, closed position covering and sealing the opening and a vertical, open position away from the opening and pivoted to either side of the container body. The lid control assembly includes a pair of guide rails mounted to the container body along opposing sides of the opening, and includes a pair of roller hinge mechanisms mounted to the lid and adapted to correspondingly engage with the guide rails and allow the lid to slide laterally along the top of the container body and to hingedly pivot at either of opposite edges of the container body. The guide rails are mounted to the container body for vertical reciprocation and each includes a pair of suspension units for biasing the guide rails in the up position.

Abstract: A roll-off hoist includes a trailer main frame having a forward end defining a first pair of tracks and having a rearward end; a roll-off hoist frame hingedly connected at its rearward end to the rearward end of the main frame to pivot between a horizontal transport position and a rearwardly inclined loading position, the hoist frame adapted to receive a container directly atop and adjacent thereto, the hoist frame defining a second pair of tracks which align with the first pair of tracks when the hoist frame is in the horizontal transport position; a trolley mounted to slide within the first and second pair of tracks; trolley stop means mounted on the trolley for engagement with coacting container stop means on a container; a cable which apparatus anchored to the hoist frame and adapted to pull the container onto the hoist frame; and actuator means interposed between the trolley and the hoist frame for moving the trolley within the first and second pairs of tracks and moving a container connected to the trol

Abstract: A vehicle mounted roll-off hoist having a main hoist frame pivotally mounted at its rearward end to a vehicle such as a semi-trailer or truck, and including a pair of hydraulic lift actuators adapted to move the main hoist frame between a horizontal position and a rearwardly inclined position. A hydraulic actuator apparatus is provided for pulling a container onto the main frame of the hoist or setting off the container from the hoist. An extensible and retractable stop carriage is slidably connected to the forward end portion of the hoist main frame. Hydraulic actuator and locking elements are associated with the stop carriage for placing the container in the optimum position for transport on the vehicle. The hoist is capable of handling containers of both the outside rail and the inside rail type.

Abstract: A transport vehicle mounted roll-off hoist having a main frame pivotally mounted on the rearward end of a vehicle such as a semi-trailer or truck, including a pair of hydraulic lift actuators adapted to move the main frame of the hoist between a horizontal position and a rearwardly inclined position. A hydraulic actuator winch is provided for lifting a container onto the main frame of the hoist or setting off the container from the hoist. An extensible and retractable stop carriage is telescopically connected to the forward end portion of the hoist main frame. Hydraulic actuator and locking means are associated with the stop carriage for placing the container in the optimum position for transport on the vehicle. The hoist is capable of handling containers of both the outside rail and the inside rail type.

Abstract: A waste material handling container for sludges and the like having a liquid tight seal between a container door and its associated opening. The seal comprises a heavily armored resilient element and a cooperating rigid element arranged to engage the unarmored portion of the resilient sealing element through a gap in its armor. The container includes a system for selectively adjusting pressure on the door to apply a substantially uniformly distributed pressure on the resilient sealing element. The latter is formed of natural rubber having good resistance to a wide range of aggressive chemical wastes.
