Work machines, drive assemblies for work machines, and methods of measuring torque of a driven component of a work machine are disclosed herein. A work machine includes a frame structure, a rotational power source supported by the frame structure, and a driven component supported by the frame structure that is coupled to the rotational power source to receive rotational power therefrom in use of the work machine. The driven component extends between a first end and a second end arranged opposite the first end. Additionally, the work machine includes a first encoder system coupled to the first end of the driven component, a second encoder system coupled to the second end of the driven component, and a control system supported by the frame structure that includes a controller communicatively coupled to the first encoder system and the second encoder system.

An internal support structure for fuel cells within a work machine having a rear end frame with an exterior frame wall in which the fuel cells are stored is disclosed. The internal support structure may include a radiator support housing, a first pedestal and a second pedestal mounted to and extending upward from the bottom wall. The radiator support housing may be disposed proximate a radiator opening of the exterior frame wall, and the pedestals may be disposed forward of the radiator support housing. A first rail may be mounted to the radiator support housing and the first pedestal, and a second rail may be mounted to the radiator support housing and the second pedestal. The internal support structure and the exterior frame wall may define fuel cell cavities for the fuel cell, and a component cavity from components of the electrical power system of the work machine.

A work vehicle includes a cab frame and a vehicle body frame having a vehicle body front portion and a vehicle body rear portion. The vehicle body rear portion includes an upper support frame, and a first support base provided on the upper support frame in a height direction. The first support base supports the cab frame rotatably about a cab rotational axis extending in the width direction. A cover is attached to the cab frame to cover a space provided above the upper support frame in the height direction when the cab frame is mounted on the vehicle body front portion. A first dust intrusion prevention mechanism is configured to overlap with a gap defined by the cab frame, the upper support frame, the first support base, and the cover when viewed in the width direction when the cab frame is mounted on the vehicle body front portion.

An electric loader is provided with a plurality of independently driven wheels. For example, a four-wheeled electric loader includes four independently operated wheels, each directly coupled to a dedicated electric motor. A fifth independent electrical motor powers the lift arm and/or any attachments coupled to an auxiliary hydraulic. A central forced-air system supplies pressurized air to each independent electric motor to cool the electric motor during operation. In some embodiments, the auxiliary electric motor powers the fan and/or air conditioner of the central forced-air system. A lever and/or electric brake may be applied to an axle of the electric motors. In some embodiments, a rotating or pivotable battery panel locks a plurality of battery cells to provide a central source of power, counter-weight the loader arm, and rotate away to provide the operator access to an internal cavity of the cab.

A work vehicle includes a vehicle body frame including a first inner frame including a first connection and a first inner projection projecting above the first connection in a height direction, a first outer frame including a second connection and a first outer projection projecting above the second connection in the height direction, and a first connection frame having a first opening and connected to the first connection and the second connection between the first inner frame and the first outer frame. A first arm hydraulic cylinder is provided to pass through the first opening. The first cover is configured to surround an outer periphery of the first arm hydraulic cylinder to cover the first opening and provided on the first connection frame to be slidably guided by the first connection frame, the first inner projection, and the first outer projection.

A swiveling working machine includes a swivel base; a working device provided on a front side of the swivel base; a battery unit; an electric motor that is driven by electric power output by the battery unit; and a hydraulic pump that delivers a hydraulic fluid by driving of the electric motor. The battery unit is disposed at a rear portion of the swivel base. The electric motor and the hydraulic pump are disposed sideward of the battery unit side by side in a front-rear direction.

Provided is a construction machine allowing a deck to be compact while facilitating water supply to a urea tank and access to a grease supply device. The construction machine includes a hose reel for grease supply disposed on a front-side portion of a deck of an upper slewing body, and a urea tank 30 disposed rearward of the hose reel on the deck and stores urea water for exhaust gas purification. The urea tank has a front surface provided with a water inlet for resupplying urea water. The hose reel is disposed deviated from the water inlet widthwise of the upper slewing body. The water inlet has a distal end located on the front side of a rear end of the hose reel.
