Ergonomically Designed for Ease of Operation

BENEFITS AND FEATURES

Electro-hydraulic Seat-mounted Controls Electro-hydraulic controls provide quick steering response, precise hook and boom control and comfortable, low-effort operation. Seat-mounted controls isolate vibrations from the operator, and provide independent seat and controls adjustment. Individual wrist pads and armrests can be adjusted independently for optimum comfort.

Pipelayer Control Right joystick places all of the boom, hook and counterweight function control in one hand. Low-effort, ergonomically designed control handle allows simultaneous precise positioning of the load line and boom. 1) Quick drop control. 2) Two-speed hook button. 3) Thumb rocker controls the counterweight functions. 4) Joystick forward lowers the hook and joystick back raises the hook. Joystick left lowers the boom and joystick right raises the boom

Quick Drop Control The quick drop control, when pushed, will allow the load on the hook to free fall to the ground. This control is to be used only in emergency situations where the load must be released immediately.

Brake and Decel Pedal The PL61 features a single, combined hystat brake and decel pedal. Two braking configurations are available for the operator’s preference. One configuration brakes the transmission only when the pedal is depressed; no engine decel will occur. The other option will slow the machine by simultaneously braking the transmission and reducing the engine speed.

Speed and Direction Control The operator controls the speed of the machine and the direction of travel with a single joystick control located on the left console. One handed steering enhances operator comfort.

BENEFITS AND FEATURES

The operator station features an ergonomic layout emphasizing simplicity, ease of use and comfort. Standard air conditioning with enclosed cab, generous legroom and superior visibility allow the operator to focus on the job. With more glass area, the operator station provides a clear view to the surrounding work site. Within the integrated Roll Over Protection Structure (ROPS), glass area is maximized for excellent sight lines around the machine and to the trench to aid productivity and enhance job site safety. A skylight window provides a clearer view during inclement weather.

Powerful Efficiency

BENEFITS AND FEATURES

Engine The Cat C6.6 engine with ACERT Technology provides a compact design with big, heavy-duty engine features for outstanding durability, reliability and performance. The C6.6 utilizes Caterpillar engineered innovations that provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance, lower emissions and years of dependable service.

Torque Rise The direct injection electronic fuel system provides a controlled fuel deliver increase as the engine lugs back from rated speed. This results in increased horsepower below rated power. A combination of increased torque rise and maximum horsepower improves response and provides greater drawbar pull.

Hydrostatic Drive The electronically controlled hydrostatic drive system automatically maintains engine speed to match the power requirements of the application for peak performance. The hydrostatic drive train also offers independent power and control of each track, for fast acceleration, infinitely variable speed control and on-the-go, direction changes for each track. The operator can command smooth “power turns” or even counter-rotation of the tracks for precise steering control in tight areas. The Cat hydrostatic drive system manages itself, freeing the operator to concentrate on using the Cat pipelayer’s superb agility, speed and maneuverability to do more productive work.

Indefinitely Variable Speed Control Hydrostatic drive provides infinite speed control from 0 to 10 km/h (0 to 6.2 mph) in forward and reverse. This lets the operator select the optimum speed for ground and job conditions. It also eliminates power interruption during shifting.

Ground Speed Balancing Hydrostatic drive provides a completely “step-less” transmission of power and automatically matches travel speed and implement loads for increased efficiency and easier operation.
