摘要： A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve ƒ(x)=4.641e0.34x The value “x” represents a horizontal direction and the function ƒ(x) represents a vertical direction.

摘要： A method for estimating the weight of loads carried by implements may include controlling an implement subject to actual weighing conditions to lift a load and receiving an input indicative of a sensed force associated with lifting the load. The method may further include determining a correlation value indicative of a correlation between first and second force values for lifting a given load with the implement as a function of the actual weighing conditions and as a function of nominal weighing conditions, respectively, where at least one of the actual weighing conditions differs from at least one of the nominal weighing conditions. Furthermore, the method may include determining an adjusted force value for lifting the load based at least in part on the sensed force and the correlation value. Additionally, the method may include estimating the weight of the load based at least in part on the adjusted force value.

摘要： A lifting arrangement for a construction machine is provided which includes a main arm (3) which is provided with a pivot connector (4). The pivot connector (4) is pivotably supported on a main arm support means (6). The main arm support means (6) is moveable in a direction which includes at least a component in the front-rear direction with respect to a frame arrangement of a construction machine to which the lifting arrangement can be applied. Based on a control of a main arm actuating element (11) and an auxiliary actuating element (21), a path of an equipment connector (5) upon moving said main arm (3) between a lowered position and a lifted position can be achieved which follows a predetermined path.

摘要： A lift arm (9) includes a first arm (11) and a second arm (12). A pivot joint portion (32) where the first arm (11) is pivoted on a bracket (8) stood at a vehicle side portion substantially corresponds to the rear end of an operation control portion. A rod (15) as a swing motion-limiting member is interposed between the bracket (8) and the second arm (12). An angle of bend formed by the first arm (11) and the second arm (12) is set to be large at a lowered position of the lift arm and small at a lifted position.
