Abstract

A lever device includes a movable bracket and a lever supported on a support shaft on a base such that they are pivotable between lowered and raised positions, first engagement portion(s) on the movable bracket, second engagement portion(s) on the lever, a cam member attached to the support shaft such that it is movable in an axial direction of the support shaft but not rotatable about the support shaft, and a biasing member to bias the cam member to engage with the first and second engagement portions. When the movable bracket etc. are in the lowered position and when they are in the raised position, the first engagement portion(s) engage(s) with the cam member to restrict the movable bracket from pivoting. When the lever pivots upward from the lowered position or downward from the raised position, the second engagement portion(s) disengage(s) the cam member from the first engagement portion(s).

Abstract

A hydraulic system for a working vehicle includes a first hydraulic pump to deliver pilot fluid to a control valve for a hydraulic actuator whose highest load pressure acts on a first fluid passage, and a second hydraulic pump to deliver hydraulic fluid whose pressure acts on a second fluid passage. A hydraulic controller is operable to control a load-sensing (LS) differential pressure between the highest load pressure and a delivery pressure of the hydraulic fluid from the second hydraulic pump. A third fluid passage to which the second hydraulic pump delivers the hydraulic fluid branches to a fourth fluid passage for flow of the pilot fluid. A solenoid valve is operable to change a pilot pressure of the pilot fluid for the hydraulic controller, and a controller is configured or programmed to control the solenoid valve to adjust the pilot pressure to change the LS differential pressure.

Abstract

The present invention provides an oil pressure control device in which a neutral position, a first function position, and a second function position are arranged in the order listed, wherein an action corresponding to the second function position can be performed without causing an action corresponding to the first function position to be performed from the neutral position. The oil pressure control device is provided with an electromagnetic proportional valve PV used for a switching action of a switching control valve (26, 32), a control unit that controls the functioning of the electromagnetic proportional valve PV on the basis of an operation command for an operating tool, and a mode-switching means capable of switching a control mode. The operating tool can be operated to one side area, a neutral area, and another side area. When the operating tool is operated to the other side area in the first mode, the control unit supplies an electric current value corresponding to an other-side first function position (Ph, Dw) to the electromagnetic proportional valve PV, and when the operating tool is operated to the other side area in the second mode, the control unit supplies an electric current value corresponding to an other-side second function position (Pd, Fr) to the electromagnetic proportional valve PV.

Abstract

Provided is a work machine to which the greatest number possible of storage devices for storing an energy source can be mounted in a suitable manner, thereby making it possible to reduce stops in travel and work relating to charging. The present invention comprises a traveling vehicle 2 which is a first moving body, a work device 3 which is a second moving body connected to the first moving body, and a sub-battery 12S which is mounted to the second moving body and stores an energy source for driving the traveling vehicle 2. In this way, the sub-battery 12S is not mounted to the traveling vehicle 2 side and is instead mounted to the work vehicle 3. As a result, there is no need to newly provide a configuration for mounting the sub-battery 12S to the traveling vehicle 2 side, and batteries can be mounted easily. When a main battery 12M is provided to the traveling vehicle 2, it is possible to continue travel and work in accordance with the capacity of the sub-battery 12S without stopping travel or work because charging of the main battery 12M is performed when the amount of power remaining therein has decreased.

Abstract

A pipe joint 1 comprises: a spigot end 3 formed on a first pipe 2; a socket 5 formed on a second pipe 4; a lock ring groove 7 formed on an inner circumference of the socket 5; a lock ring 8 accommodated in the lock ring accommodation groove 7; and a spigot end engagement portion 10 formed on an outer circumference of the spigot end 3. The spigot end engagement portion 10 is caught on the lock ring 8 in a state in which the spigot end 3 is inserted in the socket 5, thereby preventing the spigot end 3 from coming off from the socket 5. The socket 5 has, on the inner circumference, an inner tapered surface 30 expanding radially from an inner end of the socket 5 toward an opening end of the socket 5, and a bending angle limiting portion 34 projecting inward in a pipe radial direction from the inner circumference of the socket 5. The inner tapered surface 30 is formed between the lock ring accommodation groove 7 and an inner end portion 26 of the socket 5. The bending angle limiting portion 34 prevents the first pipe 2 from bending with respect to the second pipe 4 beyond an allowable angle.
