Plow conversion kit
A plow conversion kit includes a frame having a frame proximal end, a frame distal end, and a top surface extending between the proximal end and the distal end. A fixed bracket is fixed to the top surface of the frame. The fixed bracket has a fixed bracket proximal end and a fixed bracket distal end. A hydraulic cylinder has a cylinder proximal end pivotally connected to the fixed bracket and a cylinder distal end extending distally of the fixed bracket. A mounting bracket has a lower end pivotally connected to the fixed bracket distal end. A mount arm has a lower end pivotally connected to the mounting bracket. A pivot bracket has a lower end pivotally connected to the frame distal end, a central portion pivotally connected to the cylinder distal end, and a top end connectable to an upper portion of the mount arm.
Housing arrangement for a wearpad assembly
A housing arrangement for a wearpad may include a boom for a telescopic boom assembly; a plate for contacting at least one end of the wearpad when the wearpad is installed adjacent to the boom; and a fastener for securing the plate to a surface of the boom. Optionally, at least one of the plate and the boom includes a tab, where the other of the plate and the boom includes a slot, and where the slot is configured to constrain the tab in at least two directions when the slot receives the tab.
Working machine and control system
A working machine including a ground engaging structure and a propulsion system for moving the working machine via the ground engaging structure. A body is supported on the ground engaging structure, and a working arm is connected to the body and has a carriage at one end for receiving an attachment. A control system is provided for selectively and variably oscillating the carriage.
Boom assembly with yaw adjustment
A boom of a wheeled loader or digger is pivoted about a horizontal axis in a fork. Yaw adjustment is provided by opposed taper plugs which constitute a spindle of the boom. The taper portions of the plugs are eccentric with respect to the bearing portions and may be rotationally adjusted to correct misalignment of the boom in yaw. A threaded fastener locks the taper plugs to the boom.
WEAR PAD, TELESCOPIC BOOM ASSEMBLY AND WORK MACHINE
The present invention pertains to a wear pad for a telescopic boom of a work machine, comprising a base part configured to be fixedly mounted to the telescopic boom, and a top layer part configured to provide a wear-resistant, low friction sliding surface. The top layer part is configured to be releasably mounted to the base part. The invention further pertains to a telescopic boom assembly for a work machine, comprising a first boom segment having at least one first wear pad assembly mounted to a free end of the first boom segment, and a second boom segment having at least one second wear pad assembly mounted to a sliding end of the second boom segment, wherein at least one of the wear pad assemblies comprise a wear pad having a base part and a top layer part configured to provide a wear-resistant, low friction sliding surface. The top layer part is configured to be releasably mounted to the base part. Further, the present invention pertains to a work machine comprising such telescopic boom assembly.
IMPROVED TELESCOPIC LOADER
A method (30) of actuating a variable boom loading arrangement (1) that includes a variable length boom (2) that can be extended and retracted using a length actuator (3). A first end of the variable length boom (2) is pivotally attached to a frame, and the variable length boom (2) can be pivoted relative to the frame by means of a pivot actuator (5). A second end of the variable length boom (2) is used for handling loads. An input command that is given by an operator is modified if the variable boom loading arrangement (1) reaches a predefined tipping moment, resulting in a modified output command to the actuators (3, 5), so as to avoid a tipping of the variable boom loading arrangement (1). The input command is used to calculate an unmodified commanded direction of the second end of the variable length boom (2) in an external reference frame, in particular in an external Cartesian coordinate reference frame, wherein the modification scheme that is applied to the input command and that results in a modified output command to the actuators depends on the calculated unmodified commanded direction in the external reference frame.
LOADER WITH TELESCOPIC LIFT ARM
Disclosed power machines include a lift arm structure having a first arm pivotally mounted to a frame and a second arm, coupled to an implement interface, configured to telescopically extend from and retract into the first arm. A control system controls a first actuator to raise and lower the first arm, and controls a second actuator to extend and retract the second arm relative to the first arm. The control system is configured to control the first and second actuators to implement a lift operation, responsive to an operator input. During the lift operation, the first actuator raises the first arm and the second actuator extends and retracts the second arm to maintain a substantially linear path, such as a vertical path, of the implement interface or an implement attached to the implement interface.
Miniloader
A miniloader includes an articulated chassis, with a boom pivot device arranged on a front chassis part, a pivotable boom thereon including an upwardly extending first arm part which is fixedly arranged on the boom pivot device for pivoting of the boom relative to the chassis about a vertical boom pivot axis line during operation of the miniloader, a second arm part which with a first end is arranged on a free end of the first arm part and is pivotable relative thereto about a first horizontal pivot axis line between retracted and extended states, a coupling piece arranged pivotably about a second horizontal pivot axis line on a second end of the second arm part for coupling a tool thereto. In the retracted state of the second arm part, the second horizontal pivot axis line lies within the circumference of the front wheels.
Industrial vehicle
An engine exhaust system is accommodated in a counterweight portion while minimizing a change in an existing arrangement of an engine, a radiator, a radiator fan, and the counterweight portion. A body has a work device provided at the front and the counterweight portion at the rear. A ventilation path provided in the counterweight portion includes an elevated part formed between a bottom of a front portion and a bottom of a rear portion. An exhaust gas purification device and a muffler, both having a tube-like outer shape, are disposed in the rear portion of the ventilation path so as to be positioned one above the other with the purification device lying above the muffler. Pipes, which extend straight respectively from an end circumferential surface of the purification device and an end circumferential surface of the muffler toward each other, are connected via flanges.
Work machine
This work machine includes: an actuator that extends and retracts a telescopic boom; an electric drive source that is provided in the actuator and drives using power supplied from a power source; an operating unit that operates based on power of the electric drive source; an electric circuit capable of switching between a drive state in which a supply of power from the power source to the electric drive source is allowed to drive the electric drive source, and a braking state in which the supply of power from the power source to the electric drive source stops to generate a braking force to be applied to the electric drive source; and a control unit that controls the switching between the drive state and the braking state.
