A frame for cradling a rolled surface covering during installation onto a ground surface, including first and second spaced-apart end panels, a surface covering support base extending between the first and second spaced-apart panels and adapted for holding the rolled surface covering during installation. At least one lower roller extends along the support base between the first and second spaced-apart end panels at a level above the support base, and at least one upper roller extends along the support base between the first and second spaced-apart end panels at a level above the support base and is vertically spaced-apart from the at least one lower roller. The space defines a gap extending along a length of the at least one lower roller and the at least one upper roller through which a free end of the rolled surface covering is extended during installation onto the ground surface.

A controller for electronically controlling hydraulically operated lifting arms. The controller allows a wide range of quicker movement and slower movement of the lifting arms under proportional control by the operator. An electronic servomechanism is mechanically coupled to a hydraulic valve handle to control the operation of the lifting arms. The servomechanism turns a shaft in response to a proportional controller. The valve handle controls the hydraulic valve stem, allowing the hydraulically operated lifting arms to raise, lower, grip, release, and perform auxiliary hydraulic operations.

Techniques for implementing a pipe deployment system that includes a pipe reel, in which the pipe reel includes reel ends and a reel drum and the pipe reel enables a pipe segment to be wrapped on the reel drum. The pipe deployment system includes a brake assembly with a brake wheel having a shaft socket keyed with flat inner surfaces, and a shaft adapter assembly, which includes an adapter head to be coupled between the pipe reel and the brake assembly. The adapter head includes an adapter shaft keyed with flat outer surfaces, in which the adapter shaft matingly interlocks with the shaft socket and is to be partially inserted through a reel end of the pipe reel, and a rotation control pin coupled to the adapter shaft, in which the rotation control pin is to be inserted between adjacent reel spokes in the reel end of the pipe reel.

A hydraulic bale trailer comprising: a frame, where the frame is elongate and has a long axis; an axle caddy, where the frame is connected to the axle caddy such that the frame is capable of tilting on its long axis; a lock assembly connected to the axle caddy such that the lock assembly is capable of preventing the frame from tilting when the lock assembly is in an engaged position; and a hydraulic assembly with a first end and a second end, where the first end is connected to the frame and the second end is connected to the axle caddy and where the hydraulic assembly is capable of releasing the lock assembly from the engaged position to a disengaged position, allowing the frame to tilt.

A system includes a coil contacting base. The coil contacting base includes a radially curved outer surface with a radius of curvature less than or equal to a coil radius of curvature of an interior channel of a coil of spoolable pipe, and the coil contacting base includes a length greater than or equal to an axial dimension of the coil. The system also includes a side wall coupled to an inner surface of the coil contacting base. The side wall is configured to block circumferential movement of a coil restraint. The system also includes a passage disposed between the coil contacting base and the side wall. The coil restraint is configured to be disposed in the passage.
