Abstract: Marine derrick having a horizontal turn table supporting a derrick boom, a derrick post and all winches each handling separately a cargo fall, a topping lift wire and guy pendants thereon. A guy winch is located in center portion of the turn table at a level spaced from the turn table with its vertical drive shaft extended downward through an opening provided in the turn table and connected to drive motor located below the deck. The turn table is operatively connected to the drive shaft by a train of gears.

Abstract: A flexible hose assembly (10) transmits fluid between relatively movable components, such as a drive motor (16) secured to the main frame (14) of a vehicle (12) and pressurized fluid supply ports (13) resiliently supported on the main frame (14), in a constricted region where typical hose motions could result in chafing or cutting from contacts with adjacent structure. A flexed portion (39) of the hose (38) extends within a curved tubular rigid sleeve (47) which is fixed relative to one (16) of the fluid transmitting components (16, 13) and free of rigid attachment to the other (13). The diameter of the inside passage (51) of the sleeve (47) is greater than that of the hose (38) enabling limited necessary flexing while preventing more sizable and potentially damaging hose (38) movements. The curved hose portion (39) may have a radius of curvature smaller than the normal minimum bending radius as the sleeve (47) restrains kinking by preventing concentration of bending forces at one point on the hose (38).

Abstract: A sweeper-scrubber is provided which has a towable scrubbing unit. The scrubbing unit is substantially self-contained, including scrubbing brushes, a pick-up squeegee, a liquid supply tank, and a recovery tank. The sweeper has an arcuate tow bar with a steerable rear wheel located behind the center of curvature of the tow bar. The scrubbing unit has a hitch which engages the arcuate tow bar and can move longitudinally therealong to achieve a high degree of maneuverability. The scrubbing unit also has a multiple reel assembly for flexible lines which supply hydraulic fluid and electrical power from the sweeper. This assembly takes up slack in the flexible lines.

Abstract: A mobile apparatus (20) has a hydraulically operated pivoted boom (22) and a hydraulically operated pivoted arm (24) and on the free end of the arm is a hydraulically operated mechanism (26) for handling heavy loads in ways that cause torsional and bending distortion of the boom (22) and the arm (24). Coplanar steel hydraulic conduits (42a and 42b, and 45a and b to 50a and b) are slidably carried in conduit support blocks (57); and those blocks in turn are mounted on brackets (53) fixed to the arm (24) or brackets (69) fixed to the boom (22) by carrying means (56 or 72) which allows directionally unrestricted limited movement of the blocks (57) in a plane parallel to that of the conduit centers, and which also allows axial movement along lines perpendicular to that plane.

Abstract: A mobile apparatus (20) has a pivoted boom (22), and hydraulic cylinders (23a and 23b) flank the boom for moving it about its pivotal mounting (22a). Head end conduits (31a and 31b) and rod end conduits (33a and 33b) which connect the cylinders to a hydraulic pressure source are protected by guard means (35) including a unitary, rigid guard member (38) which is mounted upon the cylinders (23a and 23b) by mounting means (41) which affords limited movement of the guard member (38) relative to the cylinders (23a and 23b) in the plane of a central guard plate (39) and axially of mounting bolts (48).

Abstract: A guide device for the supply lines that lead to the work tool at the work end of a multi-axis manipulator's boom. The guide device includes a slidable block positioned to the rear of the wrist assembly of the boom and connected by a flexible cable to the work tool for controlling bending of the supply lines so as to minimize twisting thereof as the work tool is moved about a pair of intersecting axes.

Abstract: A lifting machine boom having two side walls maintained in spaced relationship to each other by a bottom wall and a top wall and a median reinforcing member dividing the interior of the boom into the first and second longitudinally extending chambers. One or more rigid pipes are attached to the median wall and run longitudinally of the boom from locations adjacent the ends. These pipes conduct pressurized fluid to and from one or more actuators carried by or associated with the boom. One said actuator is disposed in the second chamber.

Abstract: A high density polyethylene molding frames an opening in a casting through which hydraulic hoses must pass to protect the hoses from abrasion in contacting the edges and sides of the casting opening. The molding is flexible and resilient to enable it to be snapped in and out of the opening in the casting while providing a generally frictionless surface against which the hoses may be guided in their normal movement through the opening under operating conditions.

Abstract: Hydraulic fluid conduits are disposed in a counterweight which is adapted to be secured between a tractor and an earth-working implement such as a backhoe. The counterweight has a tractor-engaging side and an earth-working implement-engaging side from which the conduits extend. The conduits are equipped with hydraulic couplings for mating with the hydraulic lines from the tractor and an earth-working implement.
