Productivity Features

High Work Equipment Speed Arm quick return circuit enables loading work to be quicker than ever, by reducing hydraulic pressure loss of arm dumping. Heavy Lift Mode The heavy lift mode increases lifting force by 10%. Large Digging Force Pressing the Power Max. function button temporarily increases the digging force. Two-mode Setting for Boom Switch selection allows either powerful digging or smooth boom operation. Large Drawbar Pull and Steering Force provide excellent mobility. Swing Priority Mode The swing priority mode improves efficiency for loading dump trucks. Shockless Boom Control Switch selection reduces chassis vibration after sudden stops.

Swing Priority Mode

The swing priority mode allows the operator to use the same easy motion for 180° loading as 90° loading operations. By altering the oil flow, this setting allows you to select either boom or swing as the priority for increased production.

Work Equipment Speed

An arm quick return circuit is provided for arm dumping. This returns a portion of oil flow directly to the hydraulic tank at arm dumping to reduce the hydraulic pressure loss. Speedier loading work can be accomplished by work equipment with quicker movement.

Large Drawbar Pull and Steering Force

Since the machine has a large drawbar pull and a high steering force, it demonstrates excellent mobility even when it is on inclined sites.

Two-mode Setting for Boom

Smooth mode provides easy operation for gathering blasted rock and scraping operations. When maximum digging force is needed, switch to power mode for more effective excavating.

Shockless Boom Control

The PC850-8E0 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.

Strengthened Boom and Arm

Thanks to the large cross-sectional structure employing a high tensile strength steel with a thick plate, partition wall, etc., the boom and arm exhibit excellent durability and are highly resistant to bending and torsional stress.

Frame Structure

The revolving frame mount and center frame mount on the swing circle are no welding structure so that force is transmitted directly to the thick plate of the frame without passing through any welding.
