Speed change control apparatus for work vehicle
A speed change control apparatus for a work vehicle includes a hydraulic continuously variable speed transmission that performs speed change on power input from an engine by changing a trunnion shaft angle based on a depressing amount of a speed change pedal and outputs the power, a pedal position detector that detects a pedal position responsive to the depressing amount of the speed change pedal, and a control unit that controls a number of revolutions of the engine and the trunnion shaft angle of the hydraulic continuously variable speed transmission based on a detection value of the pedal position detector. The control unit performs control so that the trunnion shaft angle is maximized at a second pedal position set to a position shallower than a first pedal position at which the number of revolutions of the engine is maximized by a depressing operation of the speed change pedal.
Hybrid construction machine
An output command calculating section (40) of an HCU (36) restricts a battery discharge power from an electricity storage device (31) based upon a battery electricity storage rate (SOC) and a current square integrating rate (Risc) of the electricity storage device (31). Thereby, the HCU (36) transfers from a normal mode (NMODE) to a low speed mode (LSMODE) to lower a movement speed of a hydraulic actuator. A monitor display amount calculating section (50) of the HCU (36) calculates a maximum speed reduction rate (DRs) based upon a battery discharge power limit value (Plim0) and an engine output upper limit value (Pemax) from the output command calculating section (40). A monitor device (39) displays a reduction rate of the movement speed of the hydraulic actuator in the low speed mode (LSMODE) based on the maximum speed reduction rate (DRs).

WORK MACHINE WITH IMPROVED VIEWING ANGLES
A work machine configured to operate on a ground surface. The work machine comprises a frame, a cab supported by the frame and configured to house an operator of the work machine, and at least one loader arm supported on the frame and shiftable relative to the frame between a raised position and a lowered position. The frame includes (i) a forward portion and a rearward portion, and (ii) a first side and a second side. The first side and the second side are laterally separated from each other. At least the first side of the frame comprises an inner panel and a cover panel at the rearward portion of the frame. The cover panel is spaced outwardly from the inner panel. At least a portion of a top edge of the cover panel is positioned vertically lower than a top edge of the inner panel.
