A work machine includes an unload lever swingably supported by an operation box, the unload lever being configured to be swung to select whether or not to supply an operation fluid to the hydraulic actuator. The unload lever includes a second guide pin to move in a first guide groove in accordance with the swinging of the unload lever, the second guide pin being positioned on a first end of the first guide groove when the unload lever is positioned to a pushed-down position and positioned on a second end of the first guide groove when the unload lever is positioned to a pulled-up position. The first guide groove includes a first latch portion to latch the second guide pin at the first end of the first guide groove, and a second latch portion to latch the second guide pin at the second end of the first guide groove.

The reducing agent tank has a tank main body and a feed pipe. The tank main body stores a reducing agent to be supplied to an exhaust gas treatment device. The feed pipe protrudes from the tank main body. The feed pipe is provided to replenish the tank main body with the reducing agent. A support base supports a vessel for the reducing agent for replenishment of the reducing agent tank. The support base is variable in position between a developed position in which the support base is arranged at a greater distance from the tank main body than from the feed pipe in a direction of protrusion of the feed pipe from the tank main body in a plan view and a stored position in which the support base is stored in an exterior cover.

Disclosed is an operator platform designed as an exchangeable assembly unit, for mobile construction machinery, having a carriage for translational adjustment and a rotatable seat mounting for rotary adjustment of a seat, which also relates to a driver's cab with an operator platform of this kind.

A bulldozer includes a blade, an engine, first and second exhaust treatment devices that treat exhaust from the engine, and an engine cover. The first exhaust treatment device is disposed in front of the engine and lower than a first upper surface of the engine. The second exhaust treatment device is disposed above the engine. The engine cover includes a second upper surface sloping forward and downward. The engine cover covers the engine and the first and second exhaust treatment devices. Longitudinal directions of the first and second exhaust treatment devices extend along a vehicle lateral direction. In a top view of the bulldozer, the second exhaust treatment device includes a portion overlapping the engine. As seen from a side of the bulldozer, a front edge of the second exhaust treatment device is positioned forward of a rear edge of the first exhaust treatment device.

A working machine includes a machine body an operator seat mounted on the machine body, a front working device swingable upward and downward, the front working device being provided forward of the operator seat and on one side in a machine-width direction eccentric with respect to a central portion of the operator seat, and a front guard provided forward of the operator seat. The front guard includes a first frame member provided forward of the operator seat and on the one side, and a second frame member provided forward of the operator seat and on another side opposite to the one side, the first frame member includes a main rod portion defining upper and lower portions of the first frame member, extending between the upper and lower portions of the first frame member, and provided rearward of the front working device, and the main rod portion is formed to be positioned in a machine fore-and-aft direction closer to the operator seat than the second frame member.

A cabin assembly for construction equipment includes a main frame; a mount mounted on the main frame; a cabin fixed to the main frame by the mount while spaced a predetermined distance apart therefrom; a retainer for connecting the cabin to the main frame and fixing the cabin to the main frame such that the cabin is not inclined at a first angle or greater with respect to the main frame; and a support installed on one of the main frame and a lower surface of the cabin, including an end portion facing the other of the main frame and the lower surface of the cabin while being spaced apart therefrom, and when the cabin is inclined at a second angle or greater with respect to the main frame, contacting the other of the main frame and the lower surface of the cabin to support the cabin.

A canopy of a dump body for a truck comprises a deck having a length and a width greater in dimension that the length defined by a front edge, a rear edge opposite the front edge, a first side edge, and a second side edge opposite the first side edge. The deck can define an upper surface and a lower surface opposite the upper surface. In a front view the deck can define a concave shape, with a center portion and stepped portions between the center portion and the first and second side edges.

The invention relates to a rear suspension mounting assembly adapted to connect a cab to a vehicle chassis. A lower bracket is provided with a first fastener for securing it to a vehicle chassis. An upper bracket is provided with a second fastener for securing it to a cab. First and second connecting means connect the upper bracket to the lower bracket, wherein the first connecting means are adapted to rigidly connect the upper bracket to the lower bracket, the second connecting means are adapted to movably connect the upper bracket to the lower bracket. When the brackets are connected by both connecting means, the upper bracket is rigidly connected to the lower bracket, wherein the first connecting means are dimensioned to break when subjected to a threshold force at which the second connecting means remain intact and allow the upper bracket to move relative to the lower bracket.

A window assembly for attachment to a frame of a vehicle includes a window having a top, a bottom, sides, an outer surface, and an inner surface. A height of the window extends from the top to the bottom of the window. A width of the window extends between the sides of the window. A thickness of the window extends between the outer and inner surfaces. The window defines a plurality of slots. A clamp is securable to the frame of the vehicle for mounting the window assembly to the vehicle. A bolt is extendable through the clamp and window to couple the window to the clamp and frame. A fastener is engageable with the bolt to secure the window assembly to the frame.

A work vehicle includes: a cab to be boarded by an operator, the cab including a roof; and a first antenna mounted on the roof. The first antenna is positioned selectively at one of a position lower than a topmost portion of the roof, and a position protruding upward relative to the topmost portion of the roof.
