2022 Caterpillar Underground Mining (LHD) Loaders R1700

2022 Caterpillar Underground Mining (LHD) Loaders R1700

The R1700 is a huge leap forward in LHD design, technology integration and diesel emission controls.

Made possible by the Cat C13 engine and ultra-efficient hydraulics.

A true 15-tonne loader for both load and haul and truck loading.

Noticeable power and performance inside the pile – delivering quick loading cycles.

Features may include:

• We've integrated more tie down and lift points to this machine to help drop it down a mine shaft.

• TECHNOLOGY ENABLED STRENGTH

• The R1700 is a stronger, more robust machine which is clearly reflected in the new design of its structures. Using the latest engineering design and validation tools, we've given this frame strength where it needs it most, and saved weight in other locations.

• THE NON ENGINE END FRAME

• The front frame section has a new four plate design with a new, fully integrated front axle support casting at its base. This new casting absorbs greater impact, vibration and tram loads that come with the growth of the machine capacity and weight.

• LIFT ARMS AND BUCKET LINKAGE

• The lift arms on the R1700 are visibly stronger with additional steel thicknesses in key areas.

• This new design allowed us to widen access to service points to the front frame and hydraulic components.

• Our bucket linkage, cylinder attachment points and cylinder sizes have been updated to greatly improve the mechanics of loading.

• Complimenting this new geometry are brand new, redesigned buckets for this machine.

• THE ENGINE END FRAME

• The engine end frame was a complete redesign. The redesign allowed us to improve:

• The center of gravity.

• The machine's loading characteristics.

• Ride quality for the operator.

• You'll notice that we've angled the rear of the frame while maintaining our departure angle to minimize impact damage, and we've increased wear material coverage.

• Two castings have been incorporated into the rear of the frame as counterweights and to help manage loads through the frame.

• Service access points underneath the machine have been made larger.

• Where previous generations of this machine had two frame-integrated fuel tanks, the R1700 has a single bolted in fuel tank that is simple to maintain and offers approximately 12 hours of operation before refueling.

• THE HITCH

• Like the newly expanded service access on the front linkage, we have redesigned the hitch with:

• More space for service technicians to work.

• New and larger pins connecting the two frames.

• Clean and simplified hydraulic routings across the hitch.

• We've integrated more tie down and lift points to this machine to help drop it down a mine shaft.

• TECHNOLOGY ENABLED STRENGTH

• The R1700 is a stronger, more robust machine which is clearly reflected in the new design of its structures. Using the latest engineering design and validation tools, we've given this frame strength where it needs it most, and saved weight in other locations.
