MATERIAL HANDLING APPARATUS

ABSTRACT An improved material handling apparatus includes a base boom section which is rotatably supported in a cradle and a second boom section which is telescopically received within the base boom section and is movable axially relative to the base boom section. A force transmitting assembly is provided to trans-mit rotational drive forces from a tilt motor to the base boom section to effect rotational movement of the two boom sections about their longitudinal axes. This force transmitting assembly also retains the base boom section against axial and radial move-ment relative to the cradle. The force transmitting assembly includes a single force transmitting member or body which is fixedly connected at one end portion to an end wall of the base boom section and is rotatable supported by a cradle mounted thrust bearing assembly. The thrust bearing assembly holds the single force transmitting member against axial movement to thereby re-tain the base boom section against axial movement. A gear seg-ment on the force transmitting member cooperates with a gear con-nected to the tilt motor which is disposed between an end wall of the base boom section and the cradle. Upon operation of the tilt motor, the force transmitting member rotates the two boom sections relative to the cradle. The force transmitting member is provided with fluid passages and manifold rings which conduct fluid to effect operation of another motor to extend and retract the two boom sections.

The boom is then retracted which effectively causes the base section thereof to move forward toward the material handling implement while sliding on the front and rear cradle arms until the rear stop blocks engage the rear cradle arm. The bolts removed from the front stop blocks are secured between the rear stop blocks and the rear cradle arm and the bolts on the front and rear securing straps are tightened thereby readying the material handling apparatus for operation with an additional length of boom.

Telescoping boom for excavating apparatus

There is provided a telescoping boom system for an excavating apparatus which includes a linkage member having a pivot segment and lever segment pivoted about a rotating fixed boom. A first hydraulic cylinder is coupled from the fixed boom to the pivot segment. A second hydraulic cylinder is coupled from the lever segment to a retractable outer boom. The first hydraulic cylinder extends to rotate the pivot segment away from a proximate end of the fixed boom, thus forcing the lever segment to rotate towards the proximate end of the fixed boom. The second hydraulic cylinder retracts and combines with the extension force of the first hydraulic cylinder across the linkage member to provide a retraction force to the outer boom.

The controller 12 in a load handling machine 1 comprising a machine body 2 and a load handling apparatus 6, 7 that is moveable with respect to the body 2 receives a signal representative of the position of the load handling apparatus 6,7 relative to the body 2, such as the rotation angle of an arm 6 about a fixed pivot, and a signal representative of a moment of tilt of the machine and issues a signal for use by an element (16 fig 2) of the machine 1, such as a movement actuator 8, 10 or a warning indicator (17 fig. 3), to control an operation of the machine 1 when the tilting moment reaches a threshold value, the threshold value being dependent on the position of the load handling apparatus 6, 7 with respect to the machine body 2. When the tilting moment reaches a threshold value movement of the load handling apparatus 6, 7 may be restricted or prevented. The warning indicator (17 fig. 3) may be visual or audible. The tilting moment threshold value may also be dependent upon the deployment of stabilizers S. The signal representative of tilting moment may be provided by a load cell measuring the load on an axle 5.

Self-propelled working machine

A protection projection (26D) projecting from the rear face side of a load-handling device (21) to the vehicle body (2) side is provided at each cylinder installation bracket (26) of the load-handling device (21). When the vehicle body (2) reverses with a boom (12) lowered to the ground side, the protection projections (26D) hit an obstacle (A) on the ground before a rod (27C) of a fork cylinder (27) does when a lower face (2A) of the vehicle body (2) passes over the obstacle (A). This means that the protection projections (26D) can prevent the rod (27C) of the fork cylinder (27) from directly hitting the obstacle (A) and protect the rod (27C).

Carrier/excavator remote operating system

Apparatus, for the remote control of a carrier vehicle from the cab of an excavator which is rotatably mounted upon the back bed of the carrier vehicle through a center pin assembly, is accomplished with a hydrostatic pump operably connected to the crankshaft of the carrier engine. Electric controls in the excavator cab connect to the pump which selectively directs fluid to a motor which rotates a first gear which meshes with a second gear fixed to the carrier vehicle drive shaft. In alternate embodiments, the motor connects to a power take-off on the transmission. Carrier steering, braking, and throttle functions are also remotely controlled at the excavator cab through a combination of electric and hydraulic controls with the electric wires extending from the electric controls in the excavator cab, through a slip ring on the center pin assembly and to the respective function controls at various sites on the carrier vehicle. There are thus no hydraulic lines extending from the excavator to the carrier vehicle. The present invention is discussed primarily in connection with a carrier vehicle/excavator combination although other applications are also discussed.
