Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

The present invention provides a boom system 1 for breaking and manoeuvring oversize material. The boom system 1 is mounted or attached to a vehicle. The boom system 1 comprises a base 2, a column 5 protruding upwardly from the base 2 and a boom arm 3 moveably connectable to the upright column 5 at connection point 16. A moving arrangement 4 is provided to move all or part of the upright column 5 towards and away from the base 2 so that the connection 16 between the boom arm 3 and the upright column is moveable towards and away from the base 2. A mobile crusher comprising a boom system 1 for breaking and manoeuvring oversize material is also provided.

A jib assembly includes a support; a jib attached pivotally to the support for pivotal movement of the jib in relation to the support about a horizontal axis; a first linear hydraulic actuator attached to the support for regulating pivotal movement of the jib and for maintaining the jib in a specific position relative to the support; a lever arm attached unrotatably to the jib; and a draw member attached to the lever arm and to the jib; wherein the first linear hydraulic actuator is attached to the lever arm, and the lever arm is arranged to extend in the direction above the jib.

A utility loader incorporating a boom of adjustable length. The boom may include either or both of a left and right lift arm assembly, with each lift arm assembly including a rear lift arm that telescopically receives a front lift arm. Each lift arm assembly also includes an extension actuator adapted to telescopically extend and retract its front lift arm relative to its rear lift arm. A detection system may be provided and adapted to limit lift arm assembly extension based at least in part upon a load applied at a tool supported by the boom and a relative telescopic location of a front lift arm relative to its associated rear lift arm.

An industrial machine includes a frame having a base and a boom, an arm movably coupled to the boom, an attachment, a conduit, a first member, and a second member. The boom has a first end coupled to the base and a second end opposite the first end. The arm includes a first end and a second end. The attachment is coupled to the first end of the arm. The conduit extends from the frame to the arm. The first member is pivotably coupled to the frame and supports a first portion of the conduit as the arm moves relative to the boom. The second member is pivotably coupled between the first member and the arm, and supports a second portion of the conduit as the arm moves relative to the boom.
