SITE EQUIPMENT - WHAT'S NEW
New features for Cat D9T boost production and make it easy on the operator
The latest Cat D9 dozer has an exceptional reputation for excellent productivity, optimal operator comfort and robust reliability.
Caterpillar has pushed the boundaries further with new features for the D9T which include enhanced operator safety, comfort and convenience, while also refining the performance and productivity. Powered by a Cat C18 engine with ACERT Technology, rated at 306 kW (410 hp) and with an operating weight of more than 49,900 kg, it has the power to take on the toughest dozing and ripping jobs for profitable production .
The D9T cab is designed and equipped for operator productivity, safety and comfort. A low-effort electronic dozer control handle gives the operator control of all dozer functions with one hand. Operators will enjoy comfort features such as adjustable arm rests, new automatic climate control and the standard Cat Comfort Series Seat now available with optional heat and ventilation.
For added safety, the new Dynamic Inclination Monitor provides readouts of the tractor’s pitch angle and side-to-side slope. In addition, a new operator-presence system locks out the power train and hydraulic system to avoid unintentional machine movement when the operator is entering or leaving the cab, assisted by redesigned steps, handles and guardrails.
Two new pipelayers from Caterpillar
Retaining many of the features of the existing models, Caterpillar has introduced the new PL83 and PL87 pipelayers, which respond to customer needs for increased lift capacity, enhanced slope capability, easier operation, performance and transport.
The PL83 has a rated lifting capacity of 75 575 kg - a 14% increase. The PL87 has a rated lifting capacity of 97 069 kg - a 6% boost in lifting capacity. Both new models use the Cat C15 ACERT engine, with a net horsepower rating of 231 kW (310 hp) in the PL83 and 273 kW (366 hp) in the PL87.
Lift system enhancements
The increased lifting capacity is achieved by changes to the undercarriage and counterweight. On both machines, the track roller frame has been lengthened and the rear idler repositioned, giving a higher lift capacity and enhanced stability when the machines work on slopes.
A new low-profile, heavy-duty Pullmaster winch, in the hook draw works, makes for easier transport as well as increasing operator visibility.
Boom choices include 7.32 m) and 8.53 m) versions, each fabricated with high-tensile-strength steel for durability to handle added payload.
Operator station enhancements
Both models feature an improved operator station with a redesigned joystick that places all boom, hook and counterweight functions in a single right-hand control lever.
Productivity and safety are further enhanced with added mirrors that significantly increase visibility for the operator, Dual brake pedals enhance machine control, especially on slopes and for turning within a tight pipeline right-of-way. Both new models also feature a durable, redesigned ladder that allows easier access/egress from the cab.
