The second foot board (28) is rotatable between a storage position of overlapping the first foot board (26) and a use position of being rotated in the rear side of the first foot board (26). An operation regulating mechanism (29) is provided in the front side of the first foot board (26) to be engaged to the second foot board (28) when the second foot board (28) is rotated to the storage position to regulate a foot operation.

A self-propelled work machine, such as an excavator, comprising an undercarriage equipped with wheels or track chains, and a top carriage supported onto the undercarriage for 360 rotation about a vertical axis. A first articulating boom is pivotably attached to the top carriage, and a first implement is attached to the free end thereof. The undercarriage is fitted with a mounting and pivoting adapter to which a second articulating boom is attached. The adapter comprises a mounting part attached to the undercarriage and a pivoting part attached to the mounting part such that is its pivotable at least 120 about a vertical axis and having said second articulating boom attached thereto such that it is pivotable about a horizontal axis. A second implement is attached to the free end of the second articulating boom.

A load-bearing member for a linkage assembly of an implement system includes a body and a joint assembly. The body includes a pair of sidewalls, a top portion, and a bottom portion. The top and bottom portions extend between the sidewalls and are connected to an inner surface of each of the sidewalls. The body is substantially free of structural weldments disposed within an interior cavity of the body. The joint assembly includes a cylindrical tube and a reinforcement plate. The cylindrical tube extends between and is connected to the sidewalls. The reinforcement plate is connected to an outer surface of one of the sidewalls. The reinforcement plate includes a central portion defining a tube opening and is in circumscribing relationship with the cylindrical tube such that it is disposed within the tube opening.

A compact excavator includes: a swing post which is attached to a upperstructure and which can swing in a left/right direction, a working device which is attached to the swing post and which includes a boom cylinder, a counterweight, and hydraulic hoses which extend upwards between opposite side plates of the swing post, and through which pressure oil for driving the boom cylinder of the working device is guided. The compact excavator further includes a guide plate which is provided in the swing post, and which guides the hydraulic hoses downwards while restricting the hydraulic hoses from moving to approach a handrail when the hydraulic hoses attempt to expand toward the handrail due to driving of the working device.

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.

The backhoe loader includes: a vehicle body, including a first vehicle body and a second vehicle body which are connected sequentially; a loading device, arranged on the first vehicle body; a control platform, arranged on the second vehicle body and configured to rotate by 360 relative to the second vehicle body; a cab, arranged on a first side of the control platform; and an excavating device, arranged on a second side of the control platform opposite to the first side, the excavating device being configured to rotate by 180 relative to the cab. The backhoe loader can realize functions of 360 excavating and bidirectional driving. When the excavating device works, the backhoe loader can be directly moved by folding stabilizers and without changing the position of a seat back and forth, so that the excavating efficiency is improved.

A working machine includes a machine body, a traveling device travelably supporting the machine body, a hydraulic driving device to hydraulically drive the traveling device, a floor frame supported on the machine body via a mounting member, a pedal operable to brake the traveling device, the inching valve to change a flow rate of hydraulic fluid supplied to the hydraulic driving device according to operation of the pedal, and a cable operably connecting the pedal to the inching valve. The pedal and the inching valve are attached to the floor frame.

A machine may include a body, a boom link, a swing casting, and a boom. The boom and the swing casting may be configured to rotate horizontally about an axis through the boom link. The machine may further include a mounting bracket fixedly connected to the swing casting, a position sensor fixedly connected to the boom link, a first link fixedly connected at a first end to the position sensor and configured to rotate about an axis through a rotary element, and a second link fixedly connected at a first end to the mounting bracket and at a second end to a second end of the first link. The first link and the second link may be configured to rotate horizontally with horizontal rotation of the boom and the swing casting and to transfer the horizontal rotation of the boom and the swing casting to the rotary element.

The present disclosure relates to a turntable assembly and an engineering mechanical equipment. A turntable assembly for an engineering mechanical equipment includes: a turntable body; a first rotating mechanism connected to the turntable body and configured to cause the turntable body to rotate relative to an undercarriage of the engineering mechanical equipment; and a second rotating mechanism connected to the turntable body and configured to cause an upper work device of the engineering mechanical equipment to rotate relative to the turntable body. An axis of rotation of the first rotating mechanism is not co-linear with an axis of rotation of the second rotating mechanism. The second rotating mechanism includes a rotating body for connecting the upper work device. At least two hinge points arranged spaced apart along the axis of rotation of the second rotating mechanism are provided between the rotating body and the turntable body.
