摘要： One embodiment of the system comprises a towable machine having at least one hydraulic motor arranged on the machine and operable to drive at least one wheel arranged on the machine. At least one hydraulic propelling pump is arranged to supply hydraulic fluid flow via a hydraulic circuit to the hydraulic motor to selectively drive the wheel. The system has a non-operative configuration wherein hydraulic fluid flow is blocked between the hydraulic motor and the hydraulic pump. A pressure sensor is associated with the hydraulic circuit to detect an improper pressure load when the circuit is in a non-operative configuration, and operates to trigger an alarm element.

摘要： A device and system for removing structures embedded in surrounding material is disclosed. Embodiments include a powered, expandable clamp attached to a rotating cutting tool for removing manholes from roadways. Select embodiments include anchoring a clamp to a manhole and using the manhole itself as leverage to move a cutting device through the surrounding material. Alternate embodiments allow an operator, working alone from a control station, to secure the manhole remover to the manhole, cut through the surrounding roadway, remove the manhole, and deposit the manhole at another location without requiring the operator to leave the control station. Further embodiments optionally include a depth gauge indicating the penetration depth of the cutting tool, an indicator reflecting the expanded state of the clamp, a pendulum mount allowing the clamp and drum to vertically orient using gravity, and/or the ability to attach to a host machine, such as a skid-steer loader.

摘要： In certain preferred embodiments, the present invention provides a grinding machine for creating depression patterns in a surface such as asphalt or concrete. The depression pattern may be a rumble strip for alerting drivers who drift off a driving lane, or may be for other uses. Use of a depression pattern (instead of protrusions) eliminates interference with snowplow operation in areas where plows are used. In the present invention, the grinding machine is based on a trolley which moves at a uniform height along a surface, and includes a forward “gauge” wheel which controls the relative grinding drum depth based on the wheel position and rotation. In a preferred embodiment, the grinding assembly is raised and lowered relative to the trolley in correspondence with the advancement of the trolley.

摘要： An improved coupling assembly enabling a bucket to be selectively coupled to and uncoupled from a front-end loader with lifting and tilting means. A female coupling structure is integral with the bucket. A back plate of the female coupling structure bears against a front plate of a male coupling structure with no gap between such plates. An upper flange on the front plate bears upwardly against an upper flange on the back plate. Means are provided to latch the male coupling structure releasably to the female coupling structure. Vertical play between the male coupling structure and the female coupling structure is limited precisely to a specified gap between and adjustable member on the male coupling structure and a fixed block on the female coupling structure.

摘要： An operator restraint system for a front end loader which requires an operator to rotate a pair of opposed restraint arms in front of him when he is seated before the loader may be operated. Each restraint arm is pivotally mounted to a cab surrounding the operator. A park latch cable is attached to each pivotal restraint arm and the cable is additionally attached to other components including a parking brake assembly and loader control lock. The restraint arms are biased to normally assume a generally vertical inoperative position which prevents operation of the loader. After the operator is seated, he rotates the restraint arms to an operative position in front of him wherein the arms are securely stationed and cannot be rotated back to their generally vertical inoperative position until the operator releases them. The loader is incapable of being operated until the restraint arms are locked into position for securing the operator in his seat.

摘要： A quick coupler assembly for attaching a material handling bucket or the like to the free ends of lift arms extending from a loader. The quick coupler assembly includes an elongated cross member having hitch brackets on its opposite ends. Each hitch bracket includes an end which is received against the underside of an upper attachment member on the rear wall of the bucket near the top edge thereof. The opposite end of the hitch bracket is configured for engagement against a lower inclined ramp extending along the bottom rear edge of the bucket. The coupler assembly further includes an over-center locking mechanism consisting of a pivotal handle and link connected to a shaft with a wedge on the lower end of the shaft. The shaft and wedge are slidably movable in response to over-center movement of the handle and link such that the wedge moves downwardly and passes through openings in a lower hitch bracket attachment member and the lower inclined bucket ramp for locking the quick coupler assembly to the bucket. After the operator has located the bucket in a hanging position on the quick coupler assembly, the assembly is rotated rearwardly such that an end of the handle is pushed against a stop member. As a result, the handle and link are pushed over center thereby forcing the wedge downwardly through the openings in the attaching members between the hitch bracket and bucket for securely attaching the bucket to the coupler assembly.

摘要： A quick coupler assembly for attaching a material handling bucket or the like to the free ends of lift arms extending from a loader. The quick coupler assembly includes an elongated cross member having hitch brackets on its opposite ends. Each hitch bracket includes an end which is received within a socket coupling member on the rear wall of the bucket near the top edge thereof. The opposite end of the hitch bracket is configured for engagement within a lower coupling member on the bucket rear wall. The coupler assembly further includes an attaching lever which is rotatably secured to the backside of the cross member substantially at its mid-portion. The lower end of the attaching lever is movable into engagement within a coupling member on the rear wall of the bucket. The upper end of the attaching lever includes a slidable or rotatable locking bracket assembly which is selectively moved into locking engagement with a locking member on the bucket rear wall. A tilt cylinder preloads the bucket against the quick coupler assembly such that the only force required from the operator is a simple manual movement of the locking bucket assembly into a position for final coupling.
