A fall arrest device includes a housing, a braking assembly, and a coupling assembly. The braking assembly cooperates with an elongate support to facilitate controlled movement of the fall arrest device along the elongate support. The coupling assembly is interconnected between the housing and a person to be supported by the device in the event of a fall. The coupling assembly includes a universal joint to accommodate various connection arrangements between the fall arrest device and the person.

A mobile machine includes a frame and a support system for supporting the frame from a ground surface underlying the support system. The support system may include a swing member pivotally engaged to the frame. The support system may also include journal structure rigidly attached to the swing member. The support system may further include a strut engaged to the journal structure in a manner allowing rotation of the strut relative to the journal structure about a central axis of the strut. Additionally, the support system may include a ground-engaging component mounted to the strut, the ground-engaging component being configured to move along the ground surface. The support system may also include a steering actuator engaged to the frame and the strut to control rotation of the strut about its central axis and thereby control a steering angle of the ground-engaging device relative to the frame.

A ripper assembly includes a ripper frame, which has at least one slot disposed in each of two opposing sidewalls. The ripper frame accommodates a ripper shank in a channel within the ripper frame. A pin is provided to pass through the at least one slot and through a through-way in the ripper shank to constrain the ripper shank within the ripper frame. At least one pressure source supplies pressure to the ripper shank to engage the ripper shank in a position.

A crawler track machine such as a cold planar milling machine may incorporate a steering system having multiple steering modes including coordinated steering modes as well as an improved crab mode. Orientations of front and rear pairs of crawler tracks may be managed via a linear actuator control system adapted to dynamically adjust lengths of front and rear tie rods. In one disclosed embodiment, the machine may include at least a coordinated four-track steering mode, an independent front track steering mode, and a crab mode. The crab mode may involve use of automated linear actuators on the tie rods to assure that all tracks remain substantially parallel to one another, and may involve the use of lookup tables to coordinate actuator movements in response to individual parallel track angle demands as a function of steering inputs.

A foldable conveyor having a first conveyor section and a second conveyor section pivotally connected to the first conveyor section. The pivotal connection allows the second conveyor section to articulate about the first conveyor section. The foldable conveyor also includes a pivoting mechanism operatively connected to the first conveyor section and the second conveyor section. The pivoting mechanism includes a first link having one end pivotally connected to the first section. The pivoting mechanism also includes a second link having one end pivotally connected to the second section. A second end of the second link is pivotally connected with a second end of the first link. The pivoting mechanism further includes an actuator configured to pivot the second conveyor section about the first conveyor section by allowing a relative movement between the first link and the second link.
