Abstract: Grate lifters for moving grating assemblies relative to supporting structures within which the grating assemblies are installed. A grate lifter may include a main body having a first end and a second end longitudinally opposite to the first end. A grate lifter may also include at least one hook member operably engaged with the main body at the first end and configured to engage one of at least one surface bar of a grating assembly and at least one cross member of the grating assembly. A grate lifter may also include at least one tab operably engaged with the main body at the second end and configured to engage at least one lock bar of the grating assembly. The at least one tab may be configured to be adjustable from an initial position to a bent position to engage the at least one lock bar of the grating assembly.

Abstract: A heavy cycle grating system incorporating a plurality of toothed support members to support a plurality of grate slats while securing them within grating assembly. This configuration allows the present grating system to accommodate higher volume of heavy use, such as found with vehicular applications. Further provided is a grating assembly configured for longer life and improved damage and wear-resistance while simultaneously reducing noise generated during use thereof.

Abstract: A grating system provides enhanced see through characteristics and typically includes longitudinal deep bars, axial crossbars, axial filler bars between the crossbars and longitudinal joining bars which join the crossbars and filler bars to one another. The deep bars are part of a first subassembly and the other bars are part of a second subassembly which may be lowered to join the two subassemblies to one another. The crossbars and filler bars are typically seated on the deep bars. The joining bars are typically above and aligned with the deep bars. The upper surfaces of the crossbars and filler bars are usually substantially flush with one another. The grating system is configured to support vehicular and pedestrian traffic.

Abstract: A grating system typically includes longitudinal deep bars, axial crossbars, longitudinal filler bars seated on the crossbars between the deep bars and axial joining bars which join the deep bars and filler bars to one another. The crossbars are inserted lengthwise through slots formed in the deep bars. The joining bars are inserted lengthwise into holes formed in the deep bars and filler bars. The joining bars are typically above and aligned with the crossbars. The upper surfaces of the crossbars and filler bars are substantially flush with one another to form most of the upper surface of the grating system on which vehicular and pedestrian traffic typically travel.

Abstract: A grating system includes a first welded subassembly and a second non-welded subassembly joined to one another. The first subassembly includes spaced elongated bearing bars and spaced elongated cross bars extending transversely to the bearing bars. The second subassembly includes spaced elongated filler bars and spaced elongated cross bars extending transversely to the filler bars. The filler bars extend in the same direction as the bearing bars and are disposed in sets between adjacent bearing bars. The bearing bars include spaced notches in which are received the first subassembly cross bars and the second subassembly cross bars, which are aligned above the first subassembly cross bars. The subassemblies have respective upper surfaces which are flush with one another.

Abstract: A straight line, side opening dead end cable clamp includes a pivotally mounted keeper that is spring loaded on the cable clamp body to urge the keeper into an open position. The body of the clamp has a very low profile permitting it to be formed in a mold that has a straight parting line. A cable receiving groove is formed in the body at an angle to bring the axis of the cable in line with the supporting clevis. The keeper has an elongated cable compression member that is maintained in alignment with the cable receiving groove. A single and a double U bolt design are disclosed. The compressive force applied to the cable by the cable compression member and the cable supported groove in the body is maximum at the supportive end of the clamp and minimum at the mouth of the clamp. A double loop spring member couples the keeper to the body and urges the keeper to an open position to permit access to the cable receiving groove.

Abstract: A novel apparatus for clamping a cable in an overhead transmission line system. Said apparatus comprising an elongated clamp having a lower half and an upper half, said lower half having openings to receive U-bolts therethrough to secure the upper half thereto. The lower half having means for allowing the U-bolts to free the upper half from the lower half without disassembling the entire U-bolt assembly. Said means including a slot and an opening, each to receive a leg of the U-bolt, said opening having an interior beveled area to allow the U-bolt to tilt away from the clamp body and said slot permitting a leg of the U-bolt to rotate away from the clamp body. The upper half of the clamp having grooves for retaining the U-bolts, each groove on one side of the clamp having a pair of retainers adjacent thereto crimped over the U-bolt and on the opposite side having a reduced wall area to allow the U-bolt to be lifted off of the grooved area.

Abstract: A hydraulic apparatus for converting hydraulic pressure into mechanical movement for operating a tool or other device, operated by a pump block having a bore therein and a moveable plunger disposed within said bore. A cylinder is disposed over the pump block. The cylinder is captively held over the pump block and is moveable with respect thereto along the common axis. A fluid reservoir is defined between the cylinder and the pump block, and contains the hydraulic fluid. The plunger is operated by a pair of moveable arms secured to the apparatus and causes pressure to build in the fluid in an inlet chamber which communicates between the pump block and the cylinder. A pressure control valve is mounted adjacent the pump block and limits the hydraulic pressure which may be applied in the system. A release valve and apparatus is provided for releasing the hydraulic pressure and returning it to the reservoir.
