Abstract: A shovel includes a lower traveling body, an upper turning body mounted on the lower traveling body, an excavation attachment attached to the upper turning body, a posture detecting device configured to detect the posture of the excavation attachment, an instability detecting device configured to detect information on the instability of the upper turning body due to an excavation load, and a processor configured to correct the posture of the excavation attachment. The processor is configured to open an arm or a bucket of the excavation attachment in response to determining, based on the outputs of the posture detecting device and the instability detecting device, that the excavation load during deep excavation is more than or equal to a predetermined value.

Abstract: A work vehicle includes a first loader arm portion pivotably connected at one end to a frame of the vehicle and configured to slidably receive a second loader arm portion along an opposed end of the first loader arm portion. A mechanical linkage interconnects the loader arm portions and the frame. A fluid cylinder operatively connected between each of the frame and the loader arm portions is configured to raise and lower the loader arm portions between a retracted (lowered) position and an extended (raised) position. As the fluid cylinder is actuated to urge the loader arm portions toward the extended (raised) position, the mechanical linkage results in slidable movement of the second loader arm portion with respect to the first loader arm portion so that a collective length of the loader arm portions in the extended (raised) position is increased.

A cabin 3 is mounted on a turn frame 2 that makes an all-round traverse and is mounted on a vehicle body 1, and a mounting bracket 40 is provided on one end of the front end and the rear end of the turn frame 2. An excavator 4 is mounted in front of the cabin 3 by mounting and connecting the excavator 4 to the mounting bracket 40.

Abstract: A substrate holding part in a substrate processing apparatus includes a fixing table having a suction pipe and a supply pipe, and a holding member having atmosphere flow passages for vacuum-holding a substrate. The holding member is placed on the fixing table. The suction pipe is connected through a pipe to a compressor, and the supply pipe is connected through a pipe and a solenoid valve to a gas supply part. When the substrate holding part holds a substrate, the compressor sucks an atmosphere through the suction pipe to cause the holding member to vacuum-hold the substrate. When the substrate holding part releases the substrate, a gas is supplied from the gas supply part through the supply pipe by opening the solenoid valve while the suction through the suction pipe continues. The substrate holding device and the substrate processing apparatus suppress the deposition of particles on the substrate.

Abstract: An off-highway loading vehicle having a frame, a cab, and a linkage arrangement for operably attaching a work implement to the frame is disclosed. The loading vehicle includes a pair of spaced apart lift arms having a rear end portion pivotally connected to the frame and a forward end portion pivotally connected to the work implement. A lowermost edge of a forward section of the lift arms angles downwardly from a lowermost edge of a rearward section thereof. Thus, the lift arms avoid contact with the frame when in a lowered position to place the work implement adjacent a front end of the frame. In addition, a lifting device acts between the frame and the lift arms to move the lift arms between the lowered position and a raised position.

The boom structure is powered for raising and lowering in concert each of the pairs of arms through a generally vertical path for moving the front end of the boom arms and bucket along a lift path.

Abstract: Tilt linkage and lift arm systems by way of which implements including buckets, backhoes, grapples and forks and the like are mounted with respect to conventional load lifting vehicles including tractors, loaders, forklifts, bulldozers and the like wherein the tilt linkage members form at least two parallelograms having a common link through the lift arm(s) whereby the systems continuously and automatically level the implement as it is raised or lowered unless the tilt linkage is activated to change the pitch of the implement relative to the vehicle. In some embodiments more than one set of two or more parallel tilt linkages may be connected in end to end relationship between the vehicle and the implement.

Abstract: A linkage system for loading machines is mounted on two lift-arms (14) supporting a pallet-lifting fork or a bucket (22) at the ends of the lift-arms. The linkage system is so designed that when using a bucket (22) or pallet-lifting fork the linkage system will ensure that the bucket or lifting fork will take a substantially desired angular position as it is raised and lowered, without needing to make adjustments to the tilt-cylinder as the bucket or lifting fork is raised.

Abstract: A parallel translation mechanism, when connected between a first element and a second element, maintains the relative direction between the two elements constant when one of those elements is moved relative to the other. The mechanism is in part formed by first and second rigid elongated members which are pivotally connected together and are pivotally connected by the end of the first elongated member to one of the elements. A first portion of an extendable member is connected between the one of the elements and the second elongated member, and a second portion is connected between the other element and the second elongated member. The other element is also pivotally connected to a position on the second elongated member. The three members of the mechanism are connected together in such a fashion that the described relative movement between the two elements is obtained. The mechanism has particular application to forklift vehicles.

Abstract: A motor vehicle equipped with lift arms and a bucket for handling material. The vehicle has a fluid power system including piston and cylinder assemblies to pivot the lift arms between down and up positions and tilt the bucket relative to the lift arms. A bucket leveling control apparatus operates a fluid control valve in response to the pivotal movement of the lift arms to control the flow of fluid to the bucket tilting piston and cylinder assembly to maintain the bucket substantially level during the movement thereof between down and up positions. The fluid control valve is operable to supply fluid under pressure to the bucket tilt piston and cylinder assembly to move the bucket to a dump position.

Abstract: A linkage system for automatically maintaining the orientation of a bucket of a tractor loader while the lift arms are moved between raised and lowered positions is disclosed herein. Several specific embodiments are illustrated and described in detail. Each embodiment incorporates one or more links joined to the lift arms in such a manner that a portion of that linkage is maintained generally parallel to the bucket end of the lift arm. By maintaining this parallel relationship throughout the rotation of the lift arm, the bucket positioning mechanism is displaced in such a manner as to counteract the rotation of the bucket induced by the motion of the lift arms alone. The automatic self-leveling feature improves the overall productivity of the tractor loader.
