A pin actuator assembly for a telescoping boom includes a locking head having a base, an operating plate operably coupled to the base, one or more cylinder pins and/or one or more section lock arms movable in response to movement of the operating plate relative to the base. The pin actuator assembly also includes an actuator operably coupled to the operating plate and configured to move the operating plate relative to the base. The actuator includes an electric motor and a drive arm. The electric motor is configured to drive the drive arm between an extended drive arm position and a retracted drive arm position. The pin actuator assembly further includes a motion mitigator having a housing, a rod movable relative to the housing and operably coupled to the actuator, a first biasing member coupled between the rod and the housing and a second biasing member coupled between the rod and the housing.

A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.

A housing arrangement for a wearpad may include a boom for a telescopic boom assembly; a plate for contacting at least one end of the wearpad when the wearpad is installed adjacent to the boom; and a fastener for securing the plate to a surface of the boom. Optionally, at least one of the plate and the boom includes a tab, where the other of the plate and the boom includes a slot, and where the slot is configured to constrain the tab in at least two directions when the slot receives the tab.

A construction vehicle includes a telescoping boom assembly that includes a first section and at least a second section configured to nest within and to extend from the first section. At least one wear pad is positioned between the first section and the second section. The wear pad includes a length, a first surface, and a second surface spaced apart a height from the first surface. A first portion of the wear pad includes a first bending stiffness. The wear pad also includes a second portion having a second bending stiffness, wherein the second bending stiffness is different than the first bending stiffness. Optionally, the height of the wear pad between the first surface and the second surface is substantially the same in the first portion and the second portion. Optionally, the construction vehicle is a crane.

A solid mast raiser system is disclosed herein. The solid mast raiser system may include a slot configured to house a mast. Further, the slot may be further configured to be inserted in to a predrilled bore in the ground. Further, a length of the slot may be matched to a depth of the predrilled bore in the ground. Further, the solid mast raiser system may include a stanchion configured to be attached to the slot. Further, the stanchion may be concentrically aligned with the slot. Further, the stanchion may rest upon a cable. Further, the solid mast raiser system may include a launcher coupled to the stanchion through a cable. Further, the launcher may be configured to raise and retract the stanchion. Further, the launcher may be configured to be affixed to the ground. Further, the launcher may comprise a first hole concentrically aligned with the slot.

In one aspect, the present disclosure provides a wearpad for a telescopic boom assembly including a first surface for contacting an outer boom of the boom assembly, a second surface for contacting an inner boom of the boom assembly, and a length, where the first surface and the second surface extend along the length, and where the length extends along a longitudinal direction. A chamfered portion of the wearpad may have a first end at a first location along the length and a second end at a second location along the length. The first surface and the second surface may converge along the chamfered portion. Thus, a first distance between the first surface and the second surface at the first end of the chamfered portion may be greater than a second distance between the first surface and the second surface at the second end of the chamfered portion.

This disclosure relates to a wear button or pad for a telescoping boom of the type comprising at least an outer boom member comprising a threaded bore therethrough for the wear pad assembly, and an inner boom member that is slidable with respect to the outer boom member. In one form, the wear pad assembly comprises a wear pad and a base, a first of which comprises a generally cylindrical body comprising a curved external side surface comprising a screw thread via which this is threadably engageable in the threaded bore, and an internally tapered expandable collet, and the second of which comprises an externally and complementarily tapered mandrel portion, wherein in use, the externally threaded part is threadably engaged in the threaded bore and expanded therein by insertion of the externally and complementarily tapered mandrel portion in the expandable collet.

A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.

A vehicle crane having a superstructure with a jib system including a main jib mounted in a luffable manner on the superstructure, with a jib head and a luffable additional jib and at least one luffing support supported in the region of a luffing axis of the additional jib. At least one guying support of the jib system is arranged in such a manner that a tensioner starting on the one hand from the superstructure and/or from a counterweight and connected on the other hand to the additional jib is guided via the at least one guying support and the at least one luffing support. A main jib extension is incorporated between the jib head and the additional jib with the at least one guying support supported at the main jib extension to obtain a longer design of the jib system with the highest possible permissible bearing load.
