An aerial device for operating on energized powerlines is disclosed. The aerial device may have a boom assembly with a lower, electrically non-insulating boom section coupled to an upper, electrically insulating boom section. The lower and upper boom sections may be coupled by a pinned connection that utilizes structural collars and structural pins to handle loads applied to the upper boom section. The upper boom section may articulate relative to the lower boom section using a 4-bar mechanism employing a split pivot pin that enables a greater range of motion for the articulation. A modular sled that can be coupled to various boom assemblies is also disclosed.

Aerial device

A system and method for connecting a removable counterweight system to a crane including a lower assembly adapted to be connected to the counterweight system, an upper assembly adapted to be mounted to the crane, and a latch block assembly mounted to the upper assembly. The latch block assembly includes a plurality of blocks cooperating together to form a central counterbore for receiving a stud therein. The blocks are mounted within the upper assembly by at least one axle to allow for rotation of the blocks. A distal end of the stud is removably connected to the latch block assembly to attach the counterweight system to the crane.

Counterweight attachment mechanism for a crane

A quick coupling implement for an aerial device has a base, a boom assembly, the implement, and an adapter. The adapter is emplaced on a portion of the boom assembly to allow for quickly coupling the implement. The adapter comprises a boom-raise-interfacing segment with at least one opening for securing to the boom raise of the boom assembly via a retaining pin. The adapter also comprises an implement-interfacing segment that presents a complementary shape to an adapter-receptor segment of the implement. The implement may be a utility platform for supporting a utility worker.

A mobile scanner includes a base, an articulating boom assembly, a scanning assembly, and a boom-power system. The articulating boom assembly includes a proximal vertical boom section pivotably secured to the base; a distal vertical boom section; and an intermediate horizontal boom section disposed between the proximal vertical boom section and the proximal vertical boom section. The articulating boom assembly forms a general inverted U-shape when in a deployed position, so as to present an opening therethrough for the passing of an object to be scanned. The scanning assembly is disposed at least in part on the distal vertical boom section for scanning the object in the opening. The boom-power system is configured to place the articulating boom assembly into the deployed position. The articulating boom assembly is configured to remain in the deployed position without the boom-power system keeping the articulating boom assembly in the deployed position.

Stable mobile scanner

A load line guide is configured to direct a load line of an crane along a boom assembly, the load line guide comprising a guide housing and a first guide cam. The guide housing presents a gap oriented in a lateral direction and a channel oriented in a longitudinal direction. The first guide cam is pivotably secured to the guide housing and disposed in the gap. The first guide cam is configured to be selectively placed into an open position and a closed position. While the first guide cam is in the open position, the load line guide is configured to receive the load line into the channel of the guide housing; and while the first guide cam is in the closed position, the guide housing is configured to retain the load line guide within the channel of the guide housing.
