摘要： A fluid pump control for a tractor having a fluid pump controlled by an operator's handle connected to the pump by force-responsive members which do not transmit the pump vibration to the handle. The control is for a tractor transmission driven through a variable displacement pump which inherently develops vibrations. The handle is a pivotally mounted lever and the connections between the handle and the pump are four cables, and two intervening compression springs, all for transmitting the force on the lever to the pump while avoiding transmitting the pump vibrations back to the lever. The springs also are arranged with the cables to automatically return the pump to a neutral position when the operator releases hand force on the lever.

摘要： A movable cab structure and operator's compartment for a front end loader which permits complete access to all parts of the front end loader for easy servicing, repair or replacement work. In one embodiment, each base frame side member of the front end loader includes an elongated rail, a stop, and a bracket having a roller mounted thereon. Each side wall of the operator's compartment also includes an elongated rail and a roller which is mounted to the side wall by a bracket. As the operator's compartment is moved forwardly, the rails on the compartment side walls engage the rollers on the base frame side members while the rollers on the compartment side walls engage the underside of the rails on the base frame side members. The operator's compartment may then be easily moved forwardly to an extreme position until the rollers on the compartment side walls engage stops on the base frame side members. In a second embodiment, the cab structure is movable longitudinally on the side walls of the operator's compartment to an out-of-the-way position. Each compartment side wall includes a roller on its forward end for engaging an inwardly turned lip extending along the length of the cab structure. Each side of the cab structure includes a rear roller which rides along the upper end of a respective compartment side wall. In yet another embodiment of the invention, each base frame side member includes an upstanding flange member which forms a rail wherein the entire operator's compartment is capable of longitudinal movement. Rollers are uniquely arranged with respect to the rail to provide a simple effective mechanism that permits the operator's compartment to be moved forwardly.

摘要： A hand control system for a tractor having several controllable units such as hydraulic and brake units. A tubular member is rotatably mounted about its longitudinal axis and it connects to one of the units for actuating the same, and a member is pivotally mounted on the tubular member and has a handle thereon which connects to a linkage extending partly through the tubular member and connects to another of the units for operating same. The tubular member can be rotated to actuate its connected unit, without requiring actuation of the handle, and, conversely, the handle can be actuated to move its linkage and actuate its connected unit, without moving the tubular member and its unit. Also, another tractor unit, such as a brake, is connected into the system such that when the one member is pivoted upwardly on the tubular member the handle is placed in an inoperative position and the brake is automatically operated, as desired.

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.
摘要翻译： 一种用于前端装载机的操作者约束系统，其需要操作者在他操作之前就坐在其前面的一对相对的约束臂在其前面旋转。 每个约束臂枢转地安装到围绕操作者的驾驶室。 公园闩锁电缆连接到每个枢转约束臂，并且电缆另外附接到包括驻车制动组件和装载机控制锁的其他部件。 约束臂被偏压以正常地呈现大致垂直的不工作位置，这防止装载机的操作。 操作人员坐下后，他将约束臂旋转到他前方的操作位置，其中手臂被牢固地固定住，并且不能旋转回到它们大致垂直的不工作位置，直到操作者释放它们。 装载机不能操作，直到约束臂锁定到位以将操作者固定在其座中。

摘要： A modular machine including several removable components which are structurally interconnected in a manner to result in a rigid unit which is inexpensive to manufacture and easy to service or repair. The modular machine includes as its basic components a base frame assembly, an operator's control station, and a cab assembly. The base frame assembly comprises an open frame construction including opposed rectangular end members and opposed hollow rectangular side members. Ground-engaging wheels are mounted to the side members by using a unitized axle assembly including a hub and sprocket which extends into the interior of a side member. A fluid motor is mounted to the inner wall of each side member for driving the ground-engaging wheels connected to that side member. The operator's control station includes a front wall portion and rearwardly extending side wall portions. A generally U-shaped frame extends downwardly from the front and side wall portions for engagement within a complementary cavity formed by stepped inner walls on the side members of the base frame assembly. The cab assembly consists of an operator's seat attached to a box-like frame with the box-like frame being pivotally attached to the operator's control station. The cab assembly may be conveniently removed from the operator's control station or rotated to an out-of-the-way position thereby permitting complete access to the interior of the operator's control station. The base frame assembly, operator's control station and cab assembly may be conveniently disassembled to permit complete access to all parts of the machine for easy servicing, repair or replacement.

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： A reverse linkage loader bucket arm with an enclosed cylinder assembly and wherein a loader bucket is pivotally mounted on the arm and the cylinder assembly induces the pivotal action. The lift or support arm for the bucket is hollow along its longitudinal axis and the cylinder assembly is mounted within the hollow arm and projects through an open end thereof to pivotally connect with the bucket and the point of pivotal connection is to the side of the pivotal connection of the arm in the bucket away from the bucket. The cylinder fluid lines are also disposed within the hollow boom or lift arm, and thus the cylinder assembly and the lines or hoses are enclosed and thereby protected and arranged for reverse linkage connection relative to the arm and the bucket.

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.
