A lever device includes a base pedestal, a movable body, a lever, a cam body having a cam groove, a guide pin, and a first biasing member. The lever is configured to swing between a push-down position at which the guide pin is arranged in the upper groove portion and a pull-up position at which the guide pin is arranged in the lower groove portion. The first biasing member has one end connected to a first connector portion provided on the base pedestal; and the other end connected to a second connector portion provided on the cam body, is arranged behind the second lateral shaft when the lever is located at the push-down position, and is arranged in front of the second lateral shaft when the lever is located at the pull-up position.

A crane, a construction machine or an industrial truck, with a control station including at least one input means for inputting control commands, a graphical simulation module for calculating a virtual representation of the machine surroundings and/or machine components visible from the control station, such as a boom or a load hook, and a display device for displaying the calculated virtual representation, wherein a movement simulation module is provided for determining movements and/or deformations of the machine components according to the inputted control commands, depending on which the graphical simulation module calculates the virtual representation. Proposed is a data emulation using hardware components, which carry out actual actuating movements and thus simulate “actual” actuating movements of the machine to be simulated, in order to provide corresponding movement data more rapidly and with less computing performance, whereby a more realistic simulation can be achieved in real-time or almost real-time.

Disclosed are power systems, and power machines employing the power systems, having dual in-line pumps configured to supply hydraulic fluid to respective left and right side travel motors of the power machine. In some exemplary embodiments, pump pintle arm controls and a single centering mechanism for the pintle arm controls are provided. The single centering mechanism is configured to center the pintle arms for each of the two pumps. Also in some exemplary embodiments, a mechanical control linkage configuration allows the separate pump pintle arm controls to be positioned on a side of the pump substantially one behind the other. This allows hydraulic connections to the pumps to be placed on top of the pump assembly, improving the routing of hydraulic hoses in the power machine.

Provided is a cab for a work machine capable of preventing an actuator from being damaged by vibration. A cab body is formed with a doorway. A door is rotatably supported on the cab body. The door opens and closes the doorway. A closed position locking unit locks the door so as to disable it from rotating relative to the cab body. The actuator generates a driving force to unlock the door locked by the closed position locking unit. The actuator is mounted on the cab body and is supported by the cab body.

A working machine includes: an operator’s seat; and at least one pedal to be operated by being stepped on with a foot, or with feet. The at least one pedal is disposed ahead of the operator’s seat. The at least one pedal includes a pedal body extending in a predetermined direction, a pedal shaft having an axis intersecting the predetermined direction and supporting the pedal body in such a way as to allow pivotal motion of the pedal body around the axis, and a tread surface provided on an upper surface of the pedal body and being a surface on which an operator places the foot. The tread surface is sloped such that a height from the pedal body decreases gradually from a portion closer to a big toe of the foot of the operator placed thereon toward a portion closer to a little toe.

A work machine includes a frame, a traction system, an engine, an implement system, an operator cab with a roof; a machine control system, and a secondary control system. The secondary control system is configured to interface with the machine control system and includes a secondary control device, a control module, a communication module, a base plate, and two rails. The base plate is configured to support the control module and the communication module, and protect the plurality of harness connections. The two rails are configured to support the base plate in an operation orientation and a service orientation and each include a plurality of channels configured to support the base plate in the service orientation.
