Abstract:
A device for fastening a rollbar or similar attachment part on a vehicle, in particular a vibration roller, includes an inner installation sleeve, which is or can be operationally linked to a bar receptacle on the vehicle, an outer installation sleeve, which at least partially encloses the inner installation sleeve and is or can be operationally linked to the rollbar, and at least one elastomeric element, which positions the inner installation sleeve relative to the outer installation sleeve in such a way that the two sleeves are spaced apart from one another while partially forming a vibration clearance. In addition, the present invention relates to a rollbar or similar attachment parts for attachment on a vehicle, in particular on a vibration roller, having at least one device according to the above-mentioned type, which is implemented, in particular integrated on the rollbar.
Abstract:
In a construction machine such as a hydraulic excavator in which a boom of a working attachment is arranged to one of the left and right sides of a cab into which an operator gets on, a load transmission member for transmitting a lateral load imposed on the cab at the time of rollover of a machine main body to the boom serving as a load receiving member is attached to a side surface of the boom in a state that the load transmission member is elastically deformable taking a boom attachment point as a supporting point, further, a projection piece is provided for this load transmission member, and a clearance is formed between this projection piece and a left end surface of a top plate of the boom.
Abstract:
A left support pillar includes a protective portion extending substantially vertically in front of a back rest of the operator seat so as to cover an operator seat sideways, a fixing portion fixed onto a rotating frame at a position behind the operator seat, and a connecting portion adapted to extend forward from the fixing portion and to be connected to a lower end of the protective portion. The protective portion is disposed within a predetermined range of a seating surface of the operator seat and is formed upward from a position lower than an upper end of the back rest.
Abstract:
An operator protective structure equipped on a cabin of construction machine is capable of moving the cabin along with a front guard by directly installing the front guard on the cabin fixed to an upper frame to protect the operator from an object penetrating into the front of the cabin. The cabin is provided with a bottom plate on a bottom thereof, mounted on an upper frame installed on a lower driving body and independently vibrated relative to the upper frame by connecting the bottom plate to the upper frame through vibration absorbing devices. The operator protective structure includes a front guide provided with a top bar and a bottom bar and installed up and down in front of the cabin to protect the cabin from objects penetrating into a front of the cabin and a top guide formed long on a ceiling of the cabin in a front and rear direction to protect the cabin from falling objects. The top bar is connected to a front top portion of the cabin and the bottom bar is connected to a front bottom portion of the cabin, whereby the front guide and the cabin are vibrated relative to the upper frame in a single body.
Abstract:
An armrest is provided for use in vehicle operator enclosures that have limited space. It is mounted to the sidewall rather than to the seat and is pivotable between lowered and raised positions to provide greater clearance for entry into and exit from the enclosure. The armrest is ergonomically configured to support the operator's arm and hand and minimize fatigue as he manipulates the hand controls. It is L-shaped with a first fore and aft extending leg portion that has a generally U-shaped surface configured to receive the elbow, forearm and wrist of the operator. It further includes a second generally transversely extending leg portion that also has a fore and aft extending generally U-shaped surface that is aligned with the U-shaped surface of the first leg portion. The two U-shaped surfaces are aligned with the control to support the operator's elbow, forearm and wrist as he manipulates the control. For controls that are manipulated in a fore and aft direction such as levers, the U-shaped surface serves to allow sliding movement of the operator forearm while supporting it. For controls that require hand and/or wrist movements with little or no fore and aft arm movement, the second leg portion serves to support the wrist and hand.
Abstract:
A loader vehicle comprising a body having a front end and a rear end and provided with ground engageable propulsion means, an operator's compartment and a boom assembly, comprising a lift arm assembly and a pivot member which projects transversely from the inner end of the lift arm assembly on one side thereof and extends transversely across the body from said one side of the lift arm assembly and which is pivotally mounted on the body, adjacent the rear end thereof, for movement of the lift arm assembly between a raised position and a lowered position in which the lift arm assembly extends forwardly alongside the operator's compartment and means for carrying a material handling implement at an outer end of the boom assembly so as to be disposed forward of the front end of the body, wherein the pivot member is pivotally mounted, for movement about a first axis, on a torsion member, which extends transversely across the body, by first pivotal mounting means disposed at positions which are spaced apart transversely of the torsion member and the torsion member is pivotally mounted on the body, for movement about a second axis which is parallel to the first axis and which extends transversely of the body, by second pivotal mounting means disposed at positions which are spaced apart transversely of the body.
Abstract:
An apparatus controls operation of a power machine which has a frame, a seat supported by the frame, wheels supporting the frame, a drive mechanism for driving the wheels, a lift arm structure manipulated by power actuators, and a power circuit for controlling the actuators. An occupancy sensor is coupled to the power machine for providing an occupancy signal indicative of occupancy in the seat. A traction lockout mechanism locks the drive mechanism to preclude the drive mechanism from driving the wheels. A controller is coupled to the occupancy sensor, the traction lockout device and the power lockout device and controls the traction lockout device and power lockout device based upon the input from the occupancy sensor. A display is coupled to the controller for displaying the indicia indicative of an operational state based on a display output signal provided by the controller.
Abstract:
A loader vehicle comprising, a body having a front end and a rear end and provided with ground engageable propulsion means, an operator's compartment and a boom assembly which is pivotally mounted, at an inner end thereof, on the body, adjacent the rear end thereof, for movement between a raised position and a lowered position in which the boom assembly extends forwards alongside the operator's compartment and a material handling implement carried on an outer end of the boom assembly is disposed forward of the front end of the body wherein the boom assembly comprises a lift arm assembly which extends forwards along one side only of the operator's compartment.
Abstract:
A response vehicle system includes a non-transitory computer-readable storage medium having instructions stored thereon that, upon execution by one or more processors, cause the one or more processors to determine whether a response vehicle has arrived at a scene and provide a signal to switch the response vehicle from an operational condition to a locked condition at least in response to the vehicle arriving at the scene, thereby preventing undesired operation of the response vehicle.
Abstract:
A vehicle includes a cabin, a brake, a vehicle subsystem, and a processing circuit. The processing circuit is configured to receive an indication that an operator is attempting to exit the cabin and automatically engage the brake in response to the indication to prevent movement of the vehicle. The vehicle subsystem remains operational while the brake is engaged.
