A mobile apparatus moves a concrete pump hose over a base surface and has a wheeled frame in which the wheels are pivotable about a generally vertical pivot axis between a longitudinal orientation and a transverse orientation. Each of the front pair of wheels and the rear pair of wheels are coupled to a steering mechanism to permit independent pivotal movement of the respective pairs of wheels to provide four wheel steer of the frame. The hose is supported by front and rear horn members above the base surface and below the frame. An intermediate grappling apparatus engages the hose to affect elevation thereof onto the horn members. The horn members are split between a fixed portion and a pivotally movable portion that pivots away from the fixed portion to permit the hose to be elevated above the horn members. A boom apparatus can substitute for the grappling apparatus.

A mobile device includes a vibrator, an accelerometer that senses a parameter of rotation, and a processor. The vibrator includes a drive motor and a drive circuit. The accelerometer senses a speed of rotation of the vibrator. The processor analyzes the sensed speed of rotation and generates a drive voltage that is received by the drive circuit to adjust the drive motor to produce a pre-determined, desired rotational speed. In another embodiment, the accelerometer senses an amplitude of a vibration produced by the vibrator. The processor analyzes the sensed amplitude of a vibration and generates a drive voltage that is received by the drive circuit to adjust the drive motor to produce a pre-determined, desired vibration amplitude. The processor may also compare the sensed parameter with a pre-determined desired parameter of rotation and generate a signal responsive to a result of the comparison and based on stored vibrator calibration curves.

The invention is a land clearing rake that is typically mounted on a moldboard on a conventional bulldozer. The land clearing rake pivots about a shaft that is horizontally connected to the front of the moldboard. The rake is comprised of teeth connected to each other by heavy-duty plates between each of the teeth. The teeth may be arranged in one or more sections wherein the sections can be simultaneously raised or lowered by winches mounted on the moldboard. The winches are remotely controlled from the operator's seat. Thus, the land clearing rake is capable of being quickly raised or lowered by the operator while the earth moving equipment is moving back to prepare for another forward move. The ability to quickly transition between raking and grading modes significantly improves the efficiency of land clearing operations.
