Fuel Efficiency

Electronically controlled variable speed fan

The electronic control system sets the revolution speed of the cooling fan according ro the coolant, hydraulic oil, and ambient temperature; effectively uses the engine output to prevent wasteful consumption; and reduces noise during low-speed fan revolution


Shockless Boom Control

The PC1250-8R boom circuit features a shockless valve (double-check slow return valve) to automatically reduces
the amount of vibration present when operating the boom. Operator fatigue is reduced (which can improve safety and productivity), and spillage caused by vibration is minimized.

Comfortable Working Space

The wide spacious cab includes a seat with reclining backrest. The seat height and position are easily adjusted using a pull-up lever. The armrest position is easily adjusted together with the console. Reclining the seat further enables it to be fully laid back with the headrest attached.
