A boom assembly for an excavation vehicle includes a bracket configured to couple to a turret that is rotatably mounted to a debris body. Three or more telescoping support members. A first support member of the three or more telescoping support members is pivotably coupled to the bracket, a second support member of the three or more telescoping support members supports a shoe at a distal end, and a third support member of the three or more telescoping support members is disposed at least partially between the first support member and the second support member. The boom assembly also includes a single actuator. One end of the actuator is coupled to the first support member and the other end of the actuator is coupled to the second support member. The actuator is configured to extend and retract the second support member relative to the first support member.

Boom assembly for an excavation vehicle and method thereof

A boom turret for a debris body. The boom turret includes an inlet defining an inlet axis and configured to couple to a hose. An outlet defining an outlet axis and configured to rotatably couple to the debris body. The inlet axis is substantially orthogonal to the outlet axis and a debris flow path is defined within the boom turret between the inlet and the outlet. A plate is disposed between the inlet and the outlet and has a surface at least partially defining the debris flow path through the boom turret. A nozzle is coupled to the plate and extends into the debris flow path. A pressure vessel is configured to hold a charge of pressurized fluid, and the pressure vessel is coupled in flow communication with the nozzle and selectively releases the charge of pressurized fluid through the nozzle to dislodge accumulated debris within the debris flow path.

A hose reel arrangement for sewer jetting includes a reel; a hose wound around the reel; a reel frame holding the reel; and a cover arrangement. The reel frame with the reel is rotatable about a frame axis perpendicular to a horizontal mounting surface. The cover arrangement is over a majority of the reel and reel frame. The cover arrangement is selectively movable to expose a portion of the reel to provide access to the hose. The cover arrangement is fixed in position relative to the rotatable reel frame and reel.

Enclosed hose reel used for sewer jetting

A debris collection vehicle having an enclosed volume for collecting debris and a hydraulic fan drive system for creating vacuum condition in the enclosed volume is disclosed. In one embodiment, the hydraulic fan system includes a closed loop hydraulic circuit, a variable displacement hydraulic pump disposed within the closed loop circuit, and a hydraulic motor disposed within the closed loop circuit. The hydraulic fan drive system can also include an electronic or hydraulically actuated control valve constructed and arranged to adjust the output of the hydraulic motor via a displacement actuator based on pressure in the closed loop hydraulic circuit.

Hydraulic fan drive system

Devices for restraining tubular segments and methods for storing and accessing tubular segments may include a frame arrangement that has a plurality of parallel cradles for holding tubular segments and movable restraining handles for securing the tubular segments. A spring retention assembly may also be provided that has a spring force to hold the restraining handles against the tubular segments. A vehicle can be equipped to have a device for storing and accessing tubular segments, wherein the device is movable between a storage position and an access position.

Tube restraint and methods

A tank truck is provided for collecting and transporting flowable material. The tank truck may include a tank configured to store flowable material, a retractable suction hose assembly connected to the tank and supported by a retractable boom, the suction hose assembly including an arrangement of telescoping tubes and a hose, and a drive assembly for selectively adjusting the horizontal and vertical position of the suction hose.

The present invention relates to a free flow electrophoresis method between two ion permeable membranes comprising applying an electric field perpendicular to the primary carrier flow, applying a secondary carrier flow perpendicular to both the primary buffer flow and the electric field, simultaneously reversing the direction of the field and secondary carrier flow, and repeating the previous step until effective separation occurs.
