An apparatus, a system and a method may use a diamond-impregnated wire loop to cut an underwater pipeline. The apparatus may have a frame, a carriage attached to the frame and/or pulleys connected to the carriage. The diamond-impregnated wire loop may be connected to the pulleys. The carriage may move relative to the frame to direct the diamond-impregnated wire loop in a forward direction relative to the frame and/or through the pipeline.

Apparatus, system and method for using a diamond-impregnated wire to cut an object

A tree delimber including a base frame rotatably supporting a yoke and cutting head assembly. The yoke is journalled for rotation in a ring bearing on the base frame adjacent its rear end and supported by a pair of roller units adjacent its front end. Each roller unit includes a vertically adjustable roller, adjustment being possible by manipulation of a single screw shaft accessible from a corresponding side of the base frame.

A tree delimber including a base frame rotatably supporting a yoke assembly and a cutting head assembly. The yoke assembly is journalled for rotation in a ring bearing on the base frame, adjacent its front end, and supported by a pair of roller units adjacent its rear end. Each roller unit includes a vertically adjustable roller, adjustment being automatically effected by horizontal movement of a wedge driven by a control rod under the influence of fluid pressure in a hydraulic cylinder.
