A work vehicle includes a vehicle body frame supported on a ground surface by wheels, a reinforcing plate provided in the vehicle body frame, an oil equipment using oil, and a drain pan configured to receive and discharge the oil discharged from the oil equipment. The reinforcing plate defines a drain hole extending vertically therethrough. A tilted face is provided in a face of the reinforcing plate. The tilted face extends with a downward inclination from a dropping point on the reinforcing plate for the oil discharged from the drain pan to the drain hole.

The present invention relates to a device in a self-propelled construction machine with a first driving unit, which provides for a first speed of rotation (n.sub.1). By means of a planetary gear the first speed of rotation (n.sub.1) is translated into a different speed of rotation (n.sub.3) at which a working device of the construction machine, in particular a milling rotor for processing ground surfaces, can be operated.

A power distribution assembly integrated into the lower engine housing of an internal combustion engine, the assembly having a drive train with a T-box output configuration and power take off driven by the crankshaft of the engine. The drive train may power the input shafts of a pair of independent, variable drive transmissions. In one embodiment, a single actuator engages a manual clutch/brake mechanism that controls the output shaft of the power take off. In other embodiments, an electric clutch affords control of the power take off mechanism. In further embodiments, a hydraulic clutch/brake assembly allows control of the power take off, and an additional hydraulic clutch assembly may be used to control the outputs of the T-box.

An output command calculating section (40) of an HCU (36) restricts a battery discharge power from an electricity storage device (31) based upon a battery electricity storage rate (SOC) and a current square integrating rate (Risc) of the electricity storage device (31). Thereby, the HCU (36) transfers from a normal mode (NMODE) to a low speed mode (LSMODE) to lower a movement speed of a hydraulic actuator. A monitor display amount calculating section (50) of the HCU (36) calculates a maximum speed reduction rate (DRs) based upon a battery discharge power limit value (Plim0) and an engine output upper limit value (Pemax) from the output command calculating section (40). A monitor device (39) displays a reduction rate of the movement speed of the hydraulic actuator in the low speed mode (LSMODE) based on the maximum speed reduction rate (DRs).

A control system for hydraulic supply system which includes electronic load sensing is configured to adjust the pump supply pressure PSP in dependence on a determined rate of increase of a load sensing pressure LSP. Below a threshold value T of the rate of increase of the load sensing pressure LSP, the pump supply pressure PSP is adjusted so that it is higher than the load sensing pressure LSP by a stand-by pressure differential P.sub.st. At or above the threshold value T, the pressure differential is increased to include a dynamic pressure differential P.sub.dyn in addition to the stand-by pressure differential P.sub.st. A method of controlling a hydraulic system is also disclosed.

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.
