PRODUCTIVITY FEATURESPC58uu-3

Height LimiterAn adjustable boom height limiter can be set prior tooperation. When the boom reaches the pre-set heightlimit, an alarm will sound and the boom automatically stops. This function can help increase productivity byletting operators focus more on digging in tight or confined spaces.

Bucket interference prevention systemThe bucket automatically stops itself from contact withthe cab/canopy. During operation, an alarm sounds andthe equipment is stopped ifthe bucket gets too close tocontact. This feature helpsmaintain operator confidence,which can increase productivity.

Digital Depth DisplayDitching, trenching, or digging is even more efficientwith this automatic depth measurement system.Informing the operator of dig depth from ground level(absolute depth) and the depth from any pre-set point(relative depth) enables work to go much more smoothly and efficiently. This lessens the need for theoperator to stop operation or leave the cab after eachadjustment, which also increases productivity.

ROADLINER

TOPS CAB

Ideal performance has been achieved with combining the meritsof rubber and the strengths of steel in the new Road Liner shoes.Road Liners can last up to twice as long as rubber tracks undermost normal operating conditions.

Similar to all rubber tracks, pavement is not easily damaged.

Replacement is fast and easy.

Wide-ranging cost reductions are

possible by replacing only the

damaged or worn-out shoes,

which differs from the need to

replace a full rubber or steel

track.

Rubber thickness has been upgraded usinga new type of core bar, and this section thatis often sheared has been reinforced.
