摘要： A method of operating a construction machine that includes a base, support arms each pivotally coupled to the base, and a plurality of wheel assemblies each coupled to the one of the support arms, the method including, in a transport mode of the construction machine, turning a wheel of each of the wheel assemblies, independently from a wheel of another of the wheel assemblies, to a toe out orientation. The method also includes driving each support arm to a deployed condition of the support arm in an operational mode of the construction machine. Driving each support arm to the deployed condition causes the distal ends of each of the support arms to move away from one another and outwardly from the base. The method also includes locking each support arm in the deployed condition and controlling steering of each wheel in the operational mode of the construction machine.

摘要： An aerial work vehicle (AWV) includes a boom, and a work platform coupled to a distal end of the boom, where the work platform has a forward end in a direction of travel and an aft end opposite the forward end. The AWV also includes a first control device mechanically coupled to one of the forward end of the work platform or the aft end of the work platform and configured to control operation of at least the boom. In addition, the AWV includes an alternate, second, control device configured to control operation of at least the boom, which may be at least one of wireless and/or mechanically coupled to the work platform at a location different from a location of the first control device.

摘要： A support system for a vehicle includes a base and at least a first and a second support arm. Each of the first and the second support arms include a base end pivotally coupled to the base through a respective hinge assembly. Each of the first and the second support arms further include a distal end opposite the base end. The support system also includes a respective wheel assembly coupled to each distal end. Each wheel assembly includes an independently powered and steerable wheel configured to engage a travel surface, a propelling motor configured to drive a respective first support arm between a stowed condition and a deployed condition unaided while the vehicle remains stationary, and a steer actuator configured to change an angle of the wheel with respect to a respective support arm.

摘要： A load restraint fastener for use with a plurality of load restraint attachments is described. The load restraint fastener includes a body. The body includes a substantially planar portion having a front face and an opposite rear face. The substantially planar portion defines an opening and includes a first receiving portion having a receiving surface. The first receiving portion also defines a first portion of the opening. The substantially planar portion includes, in addition, a second receiving portion having a receiving surface. The second receiving portion is spaced apart from the first receiving portion and symmetric with the first receiving portion about at least one axis of symmetry. The second receiving portion defines a second portion of the opening. The body also includes a projecting portion having a receiving surface. The projecting portion extends outwardly from the rear face of the substantially planar portion.
