摘要: An engine control device for a work vehicle decides that an idling stop condition is established when the front device is in the unengaged slate, the steering device is in the engaged state, the accelerator pedal is in the non-operation state, either the transmission is in the neutral state or the parking brake device is in the engaged state or the transmission is in the neutral state and also the parking brake device is in the engaged state, and the service brake device is in the unengaged state, and stops an engine when it is decided that it passes the predetermined length of time since it was decided that the idling stop condition was established.

摘要: In an unloaded state of the bucket (3), a control device (30) calculates an unloaded moment (M0) around a hinge pin G from the pressure of the lift arm cylinder that is detected by pressure sensors (15a, 15b), the angle of a lift arm that is detected by a lift arm angle sensor 14, and dimension data extracted from a vehicle body information database (35). In a loaded state of the bucket, the control device calculates a loaded moment (M1) around the hinge pin G from the pressure of the lift arm cylinder, the angle of the lift arm, and the dimension data extracted from the vehicle body information database. The control device calculates the load (W) on the bucket by dividing the difference between the unloaded moment and the loaded moment by the horizontal distance (Lw) between the hinge pin and the gravity center position of the bucket.

摘要: Provided is a loading work vehicle capable of improving work efficiency even when working on a slippery road surface. An HST-traveling-drive wheel loader 1 comprises a step-on amount detection sensor 610, a discharge pressure detection sensor 75, a mode switch device 60, and a controller 5. The controller 5 is configured to: determine whether a limit mode is selected by the mode switch device 60; specify an operation state of the wheel loader 1 when determining that the limit mode is selected; limit maximum traction force to a first set value which is set based on a static friction coefficient μ and vehicle weight when specifying that a bucket 23 is pushed into a natural ground 100; and increase the maximum traction force from the first set value when specifying that excavation of the natural ground 100 is started.
