Abstract: Embodiments of the invention provide an interlock arrangement with a blocking feature and a locking feature secured to an interlock member. The interlock member can move between first and second interlock orientations. With the interlock member in the first interlock orientation, the blocking feature can prevent attachment of a power conduit to a power connection, such that the motor is not enabled to power a powered device, and the first locking feature can allow a first gate to open in order to provide access to the powered device. With the interlock member in the second interlock orientation, the blocking feature can allow attachment of the power conduit to the power connection, such that the motor is enabled to power the powered device, and the first locking feature can prevent the first gate from opening such that the first gate obstructs access to the powered device.

Abstract: Embodiments of the invention provide a opening and closing assembly for a rigid door panel that is rotatably attached to a roller received within a track on a door frame member. A support member can be rotatably attached to the door panel. A first pivot arm can extend inboard from the support member to pivotally attach to an inboard frame member. Upon application of an upward force to the door panel, the first pivot arm can pivot with respect to the first inner frame member to move the support member in an arcuate path. The support member can thereby move the door panel upward and inboard along a door path at least partly defined by the track, with a lower end of the door panel not extending substantially outboard of the door frame member as the door panel moves along the door path.

Abstract: A system is described for controlling the engagement of a rotating drive, such as a drive for a hose reel. A power source provides rotational power to a first rotating member. A power-transfer device extends between the first rotating member and an input portion of a second rotating member. A control member linked to the first rotating member moves between first and second orientations to move the first rotating member between engaged and disengaged positions. In the engaged position, the power-transfer device is engaged to allow transfer of rotational power from the power source to the second rotating member. In the disengaged position, the power-transfer device is disengaged such that rotational power is not transferred from the power source to the second rotating member.

Abstract: A support apparatus is disclosed for securing a material moving wing plow relative to a vehicle. The support apparatus includes a trailing link having a first and a second end. The first end of the trailing link is pivotally connected to the vehicle about a first pivotal axis. A support arm is provided for supporting the wing plow. The support arm is pivotally secured to the second end of the trailing link about a second pivotal axis. The first and second pivotal axes are disposed spaced and parallel relative to each other so that the support arm is dragged by and trails from the vehicle so that during a plowing operation, the wing plow supported by the support arm moves smoothly over the material being moved so that a potentially dangerous diving of the wing plow into the material in a vicinity of the support arm is avoided.

Abstract: A support apparatus for securing a wing plow relative to a vehicle having a front and a rear includes a mounting member rigidly secured with respect to the vehicle. A first trailing link is pivotally secured to the mounting member. A second trailing link pivotally is secured to the mounting member. A support arm for supporting the wing plow is pivotally secured to at least one of the first trailing link and the second trailing link. During operation of the wing plow, the first and second trailing links trail away from the mounting member in a direction substantially parallel to a forward direction of vehicle travel.

Abstract: A vehicle including a dump body and spreader for selectively dumping and spreading materials. The vehicle includes, at least, a chassis, a body, and a spreader apparatus with a belt mechanism. A hoist is provided which extends between the body and the chassis for pivoting the body about a hinge. A tailgate is located at the rear of the body wherein the tailgate is pivotably mounted to the body. The tailgate has an opening therein to permit material to flow therethrough from the dump body to an auger assembly. The auger assembly includes an auger, which directs material to an opening through which the material will fall into the spreader apparatus. The spreader apparatus includes a body with an inlet and outlet, a belt mechanism driven by a motor, a mounting mechanism to attach it to the vehicle. The belt is driven by a motor that is controlled by a control system located in the vehicle.
