    • PROBLEM TO BE SOLVED: To allow easy recognition of the angle of inclination of a body.SOLUTION: A dump truck 1 includes a body 12, hoist cylinders 15 for lifting the body 12 up and down, a hoist lever 21, and a CCU 22 for elongating/contracting the hoist cylinders 15. The dump truck 1 further includes a body lifting state notification device 2 having a body angle sensor 16 and an IDU 26. The CCU 22 calculates an angle of inclination from the state that the body 12 is seated on a vehicle body 11, as a rate to a turnable range defined between the state that it is seated and a body-up shockless position, on the basis of a turning angle detected by the body angle sensor 16. The IDU 26 displays the angle of inclination calculated by the CCU 22 to be zero percent when the body 12 is seated, and displays the angle of inclination calculated by the CCU 22 to be 100 percent when at the body-up shockless position.

    • PROBLEM TO BE SOLVED: To provide a drive control valve of a proportional sheet valve compensating the dynamic characteristics of the proportional sheet valve according to the dimension of a pressure difference between an inlet port and an outlet port of the proportional sheet valve. SOLUTION: When a command signal is input from an operation device 104 to a controller 106, a subtracter 106E subtracts a pressure Ps detected by a first detector 105a and a pressure Pa detected by a second detector 105b to calculate the pressure difference ΔP between the inlet prot 5a and the outlet port 5b of the proportional sheet valve 50. A selector 106F determines that the pressure difference ΔP falls under either one of a plurality of preset pressure differences ΔPA, ΔPB, ΔPC and ΔPD having different dimensions, and a compensator optimal for the compensation of the command signal is selected from a plurality of first to forth compensators 106A-106D. The selected compensator compensates the command signal and outputs a control signal corresponding to the compensation value to a solenoid 20c of a pilot valve 20 of the proportional sheet valve 50.

    • PROBLEM TO BE SOLVED: To facilitate mounting/dismounting work of an engine in a base frame, and to improve ease of work when a vehicle is assembled.
      SOLUTION: An upper cross beam 10 supporting the rear side of a cab 19 from below is formed as a member separated from the base frame 7, and this upper cross beam 10 is separably attached on right and left strut parts 7E of the base frame 7 with bolts 12. That is, when the engine 27 is installed in the base frame 7, the upper cross beam 10 is previously separated from the base frame 7. Thus, during installation work of the engine 27, only the vertical lifting-up/down of the engine 27 by using, for instance, a crane, is required, and the engine 27 is installed between the respective strut parts 7E of the base frame 7 without interference of the upper cross beam 10.
