A bulldozer according to the present application includes a main frame, and an engine, a hood and an exhaust after-treatment device are provided on the main frame, an air inlet of the exhaust after-treatment device is in communication with an air outlet of a turbine of the engine via a pipeline, and the exhaust after-treatment device is fixed to the hood. In the bulldozer, vibration generated by the engine is transmitted to the main frame through an engine supporting frame or a damping device, and then transmitted from the main frame to the hood, the transmission path of the vibration is long, thus the vibration damping becomes complicated and has a high damping value, and the vibration transmitted to the air cleaner is really small.

A battery-operated work machine is provided which can perform a work while avoiding such a situation that the work machine cannot reach charging equipment. When the remaining capacity of a battery becomes lower than a first threshold value set in advance, a controller controls an inverter such that the revolution speed of an electric motor is kept at a target revolution speed and controls a first notification device to operate, and besides switches a traveling motor to a travel first speed side, in which the displacement volume is a large volume, irrespective of an input from a traveling mode instruction device, when the remaining capacity of the battery becomes lower than a first threshold value set in advance.

A hydraulic power take-off, PTO, is provided for use with industrial drives. The hydraulic power take-off has a multi-position adapter that allows the PTO to be attached to a prime mover in a multitude of angularly indexed positions while maintaining a gravity-assisted drain and sump for the hydraulic fluid. The multi-position adapter is indexable to selectively block and allow for passage of oil from a tower housing to a clutch housing thus ensuring the hydraulic oil properly drains. As a result, the tower housing is also indexable which allows the PTO unit to be installed in a number of different configurations to meet the demands of the prime mover and the final application of the industrial machine.

A vehicle is disclosed. The vehicle may include a hydraulic system. The vehicle may include a sway bar. The sway bar may be positioned rearward of a hydraulic pump of the hydraulic system. A console having a first hydraulic input may be provided in an operator area of the vehicle.

An idle mitigation system for a bucket truck which includes an alternate source of power for the vehicle air conditioner which is coupled to the hydraulic system of the bucket truck which hydraulic system is alternately powered by an electric motor which, when run in reverse, can charge batteries.

A hydrostatic transmission pressure monitoring system includes a hydrostatic transmission and a pressure sensor data source. The hydrostatic transmission includes, in turn, a transmission casing, a pivoting yoke assembly rotatably mounted in the transmission casing, a hydrostatic pump-motor arrangement containing a hydraulic pump-motor circuit at least partially formed in the pivoting yoke assembly, and a pressure scaling device fluidly coupled to the hydraulic pump-motor circuit. The pressure scaling device is configured to generate a pressure-scaled output signal substantially proportional to a peak circuit pressure within the hydraulic pump-motor circuit. The pressure sensor data source is fluidly coupled to the pressure scaling device and is configured to generate pressure sensor data indicative of the pressure-scaled output signal.

The present invention concerns a hydraulic system comprising a hydraulic pump (130) installed on a truck tractor (10), a hydraulic pipe (160) connected to the outlet of the pump (130) and a connector (170) positioned at the outlet of the pipe (160) and designed to be connected to a complementary socket (180) provided on a trailer (20) in order to supply a ram (110) positioned on the trailer, for example for tipping purposes, characterised by the fact that it comprises a circuit selector (210) designed to connect said socket (180) selectively either to a ram (110) or a conduit (220) supplying a drive assistance circuit and an assistance circuit return conduit (250) designed to be connected to a tank (120) positioned on the truck tractor.

An excavator includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, actuators configured to drive driven portions including the lower traveling body and the upper turning body, a power storage mounted on the upper turning body and used as an energy source for driving the actuators, a cooling circuit configured to cool the power storage, and a fan mounted on the upper turning body and configured to blow air to a radiator and a condenser for cooling the radiator and the condenser. Further, the power storage is arranged such that the power storage is apart from a path in which air outside the upper turning body, by an operation of the fan, is introduced into inside the upper turning body, passes across the heat exchanging device, and is discharged to the outside of the upper turning body.

The invention relates to a system for a work machine. The power system comprises a power-split continuously variable transmission for propulsion of the work machine and a hydraulic system for work hydraulics. The power-split continuously variable transmission has a hydrostatic branch and a mechanical branch. The hydrostatic branch comprises a first hydraulic machine and a second hydraulic machine.
