Abstract: A refuse vehicle includes a chassis, an energy storage device, a body, a first electric power take-off system, and a second electric power take-off system. The energy storage device is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The body is supported by the chassis. The first electric power take-off system is coupled to at least one of the body and the chassis, and includes a first motor that is configured to drive a first hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. The second electric power take-off system is coupled to at least one of the body and the chassis, and includes a second motor that is configured to drive a second hydraulic pump to convert electrical power received from the energy storage device into hydraulic power.

Abstract: A tool allowing both the inflation and deflation of air-filled bags such as dunnage bags is disclosed. The tool comprises a sliding control to easily and safely turn the flow of air on and off. The tool is switched from inflation to deflation mode by moving the bag connecting valve from one end of the device to the other.

Abstract: A snubbing unit for running and retrieving a string of tubing into a well under pressure selectively operates in a stand alone mode and a rig assist mode. The unit has a lower frame for mounting during the stand alone mode on a snubber blowout preventer. Stationary weight supporting slips and snubbing slips are carried by the lower frame during the stand alone mode. The unit has four hydraulic cylinders with weight supporting slips and snubbing slips carried by a traveling base plate on the piston rods. A stationary base plate is mounted between the lower frame and the traveling base plate. A spacer tube is connected to and between the lower frame and the stationary base plate in the stand alone mode. In the rig assist mode, the lower frame along with the stationary weight supporting slips and the spacer tube are removed to enable a rig blowout preventer to connect to the stationary base plate.

Abstract: A tool allowing both the inflation and deflation of air-filled bags such as dunnage bags is disclosed. The tool comprises rotatable controls to easily and safely manipulate both the flow of air into the device and the mode of operation between inflation and deflation. A venturi tube is used to draw air rapidly from a bag when the tool is deployed in deflation mode, while a radial vent system dissipates the force of the air exiting the device during deflation.
