A drive arrangement is provided for moving the ground engaging structure to propel, in use, the base assembly and a connected superstructure. The drive arrangement includes a prime mover and a transmission and the drive arrangement is housed within the undercarriage. An electronic control unit (ECU) is provided for controlling the drive arrangement and/or the ground engaging structure. | 05-05-2016 |
20160121722 | Working Machine - A working machine having a body supported on a ground engaging structure and a working arm mounted to the body so as capable of performing working operations. The working machine having a drive arrangement to propel the working machine including a prime mover and a hydrostatic transmission including at least one hydraulic pump driven by the prime mover, and at least one motor driven by hydraulic fluid. The working machine also having a hand throttle for selectively setting the power output of the prime mover, a foot throttle for dynamically adjusting the power output of the prime mover in a first mode of operation, wherein the transmission is configured to operate in a second mode of operation when a predetermined criterion is met, and in the second mode the foot throttle directly controls the speed of movement of the ground engaging structure. | 05-05-2016 |
20160090282 | 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. | 03-31-2016 |
20160006384 | Method of Monitoring Power Provision of a Generator Set - The present invention provides a method of remotely monitoring the power provision of a generator set at a location comprising determining an expected electrical energy usage at a first location, providing a generator set configured to provide electrical energy to power or devices at the location, the generator set arranged to provide an amount of electrical energy to meet the determined expected electrical energy usage, and the generator having a telemetry module to monitor and transmit electrical energy supply data to a second location, the telemetry module monitoring the supply data over a predetermined period and transmitting the supply data to the processor, analysing the supply data to determine a power supply profile at the first location, and comparing the power supply profile with the expected power usage and/or the power supply specifications of the generator set. | 01-07-2016 |
20150376865 | VEHICLE - A method of orientating a materials handling vehicle to a desired angle includes providing a first and second stabilizers on the right and left sides, respectively, of a chassis and being selectively engageable with the ground, providing a controller to control operation of the first and second stabilizers in response to an input, positioning the vehicle on ground with the first and second stabilizers being disengaged from the ground such that the chassis is at an initial roll angle, providing a desired roll angle, providing an input to the controller requiring deployment of the stabilizers to simultaneously deploy the first and second stabilizers, and upon detection of a change in roll angle away from the desired roll angle caused by engagement of one of the stabilizers with the ground, the controller automatically stops deployment of one stabilizers and continues deployment of the other stabilizer. | 12-31-2015 |
20150059522 | TRANSMISSION ARRANGEMENT - A transmission arrangement including a torque converter, a first shaft fixed to rotate with a turbine of the torque converter about an axis, a second shaft fixed to rotate with a casing of the torque converter about said axis, a gear mounted on the first shaft and being fixed to rotate with the first shaft and a clutch selectively engageable to cause the first shaft to be fixed to rotate with the second shaft and being selectively disengageable to allow the first shaft to rotate relative to the second shaft, the clutch being rotatable about said axis. | 03-05-2015 |
20150027789 | METHOD OF WEIGHING A LOAD - A method of weighing a load lifted by a lifting arm of a machine is disclosed and includes receiving a signal from an axle sensor, said signal representing a force exerted on an axle as a result of lifting the load, receiving a further signal from a further sensor, said further signal representing an angle or slope of the lifting arm relative to a chassis of the machine, and calculating, from the received signal and the received further signal, the weight of the load lifted by the lifting arm. | 01-29-2015 |
