561M^Non-Current

Cat 3116 Engine

Caterpillar 3116 engine performs at full-rated net power of 82 kW (110 hp) at 2100 rpm with high torque rise of 36%. High horsepower, combined with high torque rise, give the 561M the durability needed on the challenging jobs. Moreover, this engine meets all the latest emission regulations around the world.

Turbocharged

Turbocharging improves response and performance at low to medium engine speeds.

Fuel System

Direct unit injection fuel system eliminates external high pressure fuel lines and provides excellent control of injection timing with individually metered, high-pressure, direct-injection of fuel. Result is improved engine response and reliability plus low fuel consumption and emissions.

Mounting

Resilient engine mounting for quieter operation and less vibration.

Design

Long-life design

• One-piece, stress relieved, cast iron cylinder block for increased rigidity.
  
• High-strength, one piece cylinder head with replaceable stainless steel intake valve seat and nickel alloy exhaust valve seat.
  
• Optimized camshaft location, short pushrods and roller followers to reduce flexing.
  
• Full-length, water-cooled cylinders for maximum heat transfer.
  
• Large engine oil cooler to with forged steel crown for added durability.
  
• Low-mounted oil pump maintain optimum engine oil temperature.
  
• Main and rod bearing surfaces increased for better wear life.
  
• Two-piece articulated piston for quick start-up lubrication.
  

Maintenance

Easy maintenance. The engine can be rebuilt for a second life. Caterpillar remanufactured parts are available to economically replace many components. Some innovative maintenance features of the 3116 engine:

• Parent-metal cylinder block can be rebored twice and dry-sleeved.
  
• Connecting rods can be removed through the tops of the cylinders.
  
• Camshaft followers and pushrods can be easily replaced without removing the camshaft.
  
• Water pump can be serviced as a unit or rebuilt.
  

Radiator (IMRM)

Improved multiple row modular radiator efficiently cools the engine for optimum engine performance in tough environments and applications.

Torque converter

Torque converter responds to changing load conditions by providing torque multiplication for increased drawbar pull while protecting the drive train from shock loads.

Transmission

Power shift transmission. Proven planetary design delivers fast, smooth speed changes while distributing loads over multiple gears for long life. Perimeter-mounted clutches provide superior heat dissipation and a large contact area for long service life.

Clutches and Brakes

Separated clutches and brakes. Oil-cooled, hydraulically actuated multiple-disc clutches and brakes for smooth, precise turns.

Final drives

Final drives. Precision, high load capacity gears and bearings give long-lasting performance and durability.

Mainframe

High strength steel mainframe. The 561M mainframe absorbs high impact shock loads and twisting forces.

Testing

Structural testing analysis is used to verify and ensure integrity of the mainframe.

Robotic welding

Robotic welding provides deep penetration and consistency for long life.

Precision

Precision top level machining for perfect alignment of bores and surfaces.

Roller Frames

Roller frames are tubular, to resist bending and twisting, with reinforcement where operating stresses are the highest.

• Non-oscillating roller frames for greater stability in pipelaying applications.
  
• The recoil system is sealed and lubricated.
  
• Improved pipelayer structure mounting.
  

Final Drives

Final drives and associated power train components are raised above the work area, isolating them from the ground-induced impact loads, as well as pipelayer loads, extending power train component life.

Sprocket Position

Sprocket position keeps sprocket teeth, bushings and final drives away from the abrasive materials and moisture, resulting in longer final drive gear and seal life.

High Flange

High flange improved track rollers (optional) combined with center or full length roller guards attachments greatly improved track guiding for demanding side slope conditions.

Track Shoes

Track shoes are 510 mm (20”) single grouser shoes made from heat-treated, rolled steel for added strength. Long track frame and wide gauge enhance track contact area, providing a very stable working base.

Heavy Duty Sealed and Lubricated

Permanently coats the track pin with a sealed-in lubricant, minimizing metal-to-metal contact.

• Virtually eliminates internal pin and bushing wear.
  
• Lubricant is held in a reservoir in the track pin.

Cab

Operator's station provides excellent comfort and convenience. The new counterweight design provides improved viewing area from the machine.

Steering

Pipelayer steering clutch levers are easy-to-reach, low-effort controls. They are independently actuated for sure, precise steering.

Seat

The seat is ergonomically designed and fully adjustable for maximum comfort. The seat cushion reduces the pressure on the lower back and thighs while allowing unrestricted arm and leg movement.

Instrument Panel

Instrument panel is the Electronic Monitoring System (EMS) for monitoring critical machine functions. There is also a gauge group displaying fuel level, coolant, and power train oil temperatures.

Brakes

Separated brakes are independent of the steering clutch function to give the machine precise steering control.

Controls

Pipelayer controls are low effort and allow simultaneous, precise positioning of the load line and boom.

Load Line Speed

Load line speed range is controlled by a push-pull knob that allows the operator to select high or low.

Counterweight

Counterweight control adjusts the position of the counterweight for added machine stability.

Access

Simplified entry by adding a ladder on the right rear side of the machine.

Winch and Boom

Winch and Boom

• Independent hydraulic winches drive boom and hook drawworks.
  
• Oil-disc brakes provide smooth operation, positive retention of boom and hook positions.
  
• Modular design allows fast replacement, easy field service, and testing.
  
• Infinitely variable speed controls for both boom and hook allow precise control.
  
• Tubular, cast-steel boom is rugged, delivers better fatigue life.
  
• Replaceable boom-mount bearings.
  
• Symmetrical boom simplifies installation.
  
• Emergency free-fall function on load line control allows the operator to drop the load quickly.
  

Counterweight and Frame
