A swivel working machine includes a swivel base, a prime mover installed in the swivel base, a working device provided at the swivel base, and a support mechanism that supports a fuel cylinder in a rotatable manner around a pivot shaft. The fuel cylinder contains fuel for the prime mover. The support mechanism includes a support rotating body that supports the fuel cylinder and that rotates around the pivot shaft, a rotational-position defining mechanism including a pin that defines a rotational position of the support rotating body around the pivot shaft, and an adjustment mechanism that adjusts a position of the pivot shaft relative to the pin.

Swivel working machine

A swivel working machine includes a swivel base, a battery, a support to support a battery on or above the swivel base, an electric motor to be driven by electricity outputted by the battery, a hydraulic pump to be driven by the electric motor to deliver hydraulic fluid, a support portion to support the electric motor and the hydraulic pump on or above the swivel base. The support portion is separate from the support body and attached to the swivel base via a plurality of mounting devices.

A swiveling work machine includes a swivel base, a prime mover provided on the swivel base, a work device provided on the swivel base, and a support mechanism to support a fuel cylinder storing fuel for the prime mover.

Swiveling work machine

A working machine includes: a machine body; a prime mover that is mounted on the machine body; a fuel cylinder that contains a fuel; a vaporizer that vaporizes the fuel sent from the fuel cylinder and supplies the fuel to the prime mover; a temperature detector that detects a temperature correlating with a decrease in the temperature of the vaporizer; and a controller that imposes restraint on the flow rate of the fuel flowing from the vaporizer to the prime mover when the temperature detected by the temperature detector is lower than or equal to a first temperature.

Working machine

Backhoe loader

A working machine includes a machine body, an operation fluid tank mounted on the machine body, a hydraulic device to be operated by an operation fluid supplied from the operation fluid tank. A valve unit includes a plurality of control valves to control the hydraulic device. The control valves are arranged along a horizontal direction. A switch valve is to be connected to the control valves. A first tube member includes a first fluid tube to connect the control valve and the switch valve to each other and supports the switch valve above the control valve.

Backhoe

The present invention is aimed to provide a working machine provided with: a condenser unit including a condenser of an air conditioner and a cooling fan for cooling the condenser, the condenser unit being disposed in a side of a cabin; and a protection cover covering above the condenser unit, capable of reducing propagation to an operator side of an air intake sound caused by inhalation of air in the protection cover through an air intake vent when the cooling fan causes a wind. In this working machine, each of air intake vents for taking cooling air into the protection cover is formed in an upper surface side of the protection cover and in each of wall parts oriented in a direction opposite to a direction visible from an operator in the cabin.

Working machine having a condenser and protection cover

A control change system for a backhoe in a construction vehicle, comprising a plurality of pilot valves for generating a pilot pressure corresponding to operations of a first and a second control levers, respectively, and a hydraulic switching unit for relaying the pilot pressure from the pilot valves and supplying the pilot pressure to a plurality of control valves. This switching unit includes a plurality of slidable spools for supplying the pilot pressure from the pilot valves selectively to the control valves. The control system further includes a first and a second switching members for selectively sliding the plurality of slidable spools. The first switching member is operable to select the swing cylinder or the hydraulic motor to be controlled by a shift in one direction of the first control lever. The second switching member is operable to switch interlocks between the first and second control levers and a boom cylinder and an arm cylinder.
