Abstract: A material spreader for a heavy duty vehicle is provided having a hopper capable of carrying and distributing a particulate material, a longitudinally extending conveyor to move material within the hopper, a pivotably attached discharge chute and optionally, one or more liquid storage tanks secured to the exterior of the hopper by a securement system comprise a series of one or more straps connected on each end to a c-shaped cross member affixed to the vehicle or hopper body.

Abstract: An apparatus for depositing associated materials, including but not limited to salt or sand, onto a surface includes a material spreader hopper, a conveyor to convey associated material in the hopper toward an opening at one end of the hopper; a feed gate adapted to selectively close the opening, an extension and a spreader adapted as described herein, to mount to the extension.

Abstract: A safety interlock system is disclosed that can be selectively actuated to prevent or enable access to a conveyor mechanism of a spreader. When actuated to prevent access, the safety interlock prevents a top cover from moving to a position that allows access to the conveyor through an open top of the trough and prevents a hopper door from moving to an opened position wherein an operator can access the conveyor mechanism through a bottom opening of the trough. The safety interlock system can be configured such that a hydraulic drive motor is disconnected from the conveyor mechanism before allowing the top cover and the door to move to positions providing access to the conveyor mechanism.
