The plurality of outriggers are coupled to the frame base. The demolition apparatus is coupled to and supported by the frame base. The demolition apparatus includes a main body rotatably coupled to the frame base, an arm extending from the main body between two of the plurality of support members, one or more gripping members coupled to the arm, and a motor configured to selectively rotate the main body relative to the frame base. The water reservoir is coupled to and supported by the platform of the frame. Additionally, the water reservoir provides water to the demolition apparatus.

A construction vehicle includes a chassis having a front end and a rear end. The construction vehicle also includes an operator cabin supported by the chassis and a hood proximate to the rear end of the chassis. The construction vehicle further includes a hood structure for supporting the hood. The hood structure includes a first frame member coupled to the chassis proximate to the rear end and a second frame member disposed distal to the rear end and proximal to the operator cabin. The second frame member is coupled to the chassis by a mounting assembly. The mounting assembly includes a plate member connected to the second frame member. The mounting assembly also includes a first mounting device connecting a first end of the plate member to the chassis. The mounting assembly further includes a second mounting device connecting a second end of the plate member to the chassis.

Systems and methods are disclosed herein for controlling cooling fans in a self-propelled work vehicle having a main frame supported by wheels or tracks. The cooling fans direct ambient air in accordance with at least one inlet in the main frame, and selectively operate in first and second opposing directions. A perception system is supported by the main frame and configured to provide perception data (e.g., perception data) corresponding to a field of vision which includes the at least one inlet and at least a portion of an associated working area. A controller obtains the perception data and automatically determines characteristics relating to contamination of the cooling system based at least On the perception data. The controller further generates output signals to the cooling fans based on at least one of the determined contaminant characteristics, for example a debris location, type, density, and/or quantity as relating to contamination of the cooling system.

A work vehicle includes a cover having a center cover portion, a first side cover portion, and a second side cover portion. The center cover portion includes a punching metal and has a substantially rectangular shape. A first side and a second side of the rectangular shape face each other in a width direction, and a third side and a fourth side of the rectangular shape face each other in a front-rear direction. The first side cover includes a punching metal, has a substantially rectangular shape, is connected to the center cover portion at the first side, and is inclined downward in the height direction relative to the center cover portion. The second side cover includes a punching metal, has a substantially rectangular shape, is connected to the center cover portion at the second side, and is inclined downward in the height direction relative to the center cover portion.

Compact tool carriers having a loader mounted to a low-profile mainframe are disclosed. In some embodiments, the pivot points of the mainframe about which the loader is pivoted are low relative to the mainframe to reduce the mainframe size and to lower the center of gravity to improve the stability of the compact tool carrier during use.

A work vehicle includes a hydraulic oil tank that tanks a hydraulic oil, a hydraulic pump connected via a first hydraulic hose to the hydraulic oil tank, and a hydraulic equipment connected via a second hydraulic hose to the hydraulic pump. The hydraulic pump is placed in a position higher than a liquid level of the hydraulic oil in the hydraulic oil tank. At least part of the second hydraulic hose is placed in a position lower than the liquid level.

A work vehicle includes an arm cylinder configured to raise an arm assembly. A front plate is attached to a vehicle body frame in front of the arm cylinder. A back plate is attached to the vehicle body frame in back of the arm cylinder. A side plate is attached to the front plate and the back plate opposite to the vehicle body frame with respect to the arm cylinder. A bottom plate is attached to the vehicle body frame and the side frame below the arm cylinder. The front plate extends in a reference direction in which the arm cylinder is directed when a work equipment attached to the arm assembly is grounded. The bottom plate includes a downward extending portion extending in the reference direction. The downward extending portion, the front plate, the side plate, and the vehicle body frame define an opening below the arm cylinder.
