Cat Underground Mining Load-Haul-Dump (LHD) Loaders R1600H
Product Feature
Power Train – Transmission
Power Shift Transmission
The Cat four-speed planetary power shift transmission is matched with the Cat C11 diesel engine to deliver constant power over a wide range of operating speeds and grades.
Robust Design
Designed for rugged underground mining conditions, the proven planetary power shift transmission is built for long life between overhauls.
Torque Converter Lockup Clutch
Combines maximum rimpull while in torque converter drive with the efficiency and performance of direct drive when the lockup clutch is engaged. The lockup clutch delivers more power to the wheels for superior power train efficiency.
Electronic Auto Shift Transmission
The electronic auto shift transmission increases operator efficiencies and optimizes machine performance. The operator can choose between manual or auto shift modes.
Transmission Neutralizer
The operator can engage the service brakes and neutralize the transmission, maintaining high engine rpm for full hydraulic flow, enhancing digging and loading functions.
Final Drives
Cat final drives work as a system with the planetary power shift transmission to deliver maximum power to the ground. Built to withstand the forces of high torque and impact loads.
Oscillating Rear Axle
Oscillating rear axle ensures four-wheel ground contact for maximum traction and stability at all times.
Brakes
Fully enclosed oil immersed disc brakes incorporate independent service and parking brake pistons. Hydraulic actuated independent circuits provide improved performance and reliability.
Power Train – Engine – The Cat C11 engine – innovative technologies optimize performance.
The Cat C11 engine provides unequalled lugging force while digging, tramming and traversing steep grades. Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times. Mechanically Actuated, Electronic Unit Injection (MEUI™) high-pressure, direct injection fuel system electronically monitors operator demands and sensor inputs to optimize engine performance. Air-to-air aftercooling provides improved fuel economy by packing cooler, denser air into cylinders for more complete combustion of fuel and lower emissions. Oil coiled pistons increase heat dissipation and promote longer piston life. The crankshaft is forged and induction hardened for long-term durability.
The Cat C11 engine features the optional Ventilation Reduction (VR) Package. The VR Package incorporates selective engine hardware and software to reduce diesel particulate matter in the engine exhaust. Engines equipped with the VR Package feature a significant ventilation rate reduction, maintains fuel consumption, and maintained or improved product performance. VR Package availability is subject to regional regulatory compliance. Engines that emit equivalent to U.S. EPA Tier 3 and EU Stage IIIA are also available.
A Cat Diesel Particulate Filter can be used with the VR engine package. This filter compliments the VR engine by further reducing particulate matter in the exhaust. Requires the use of ultra-low sulfur diesel (15 ppm) and CJ-4 low ash engine oil.

Hydraulics
Hydraulic System
Powerful Cat hydraulics deliver exceptional digging and lifting forces for fast cycle times. High hydraulic flow rates provide fast hydraulic cylinder response and powerful lift forces. Large-bore lift and tilt cylinder delivers exceptional strength, performance and durability.
Pilot Controls
Low effort, pilot operated joystick implement control with simultaneous lift and tilt functions optimizes operating efficiency.
Cat Hydraulic Hose
Field proven Cat high pressure XT hydraulic hoses are exceptionally strong and flexible for maximum system reliability and long life in the most demanding conditions. Reusable couplings with O-ring face seals provide superior, leak free performance.
Optional Ride Control
The optional ride control system uses a nitrogen filled oil accumulator in the hydraulic lift circuit to act as a shock absorber for the bucket and lift arms. The lift arm and bucket response to movement is dampened over rough ground, reducing fore and aft pitch, improving cycle times and load retention. A smoother, more comfortable ride gives operators the confidence to travel at speeds above 5 km/h (3 mph) during load and carry operations.

Structures
Frame Design
The frame is engineered to withstand extreme forces generated during loading and tramming cycles. Precision manufacturing process ensures all structures are consistently built to high quality. Deep penetration and consistent welds throughout the frame ensures structures are solidly fused to provide sturdy platform for the linkage and the axles. The design and manufacturing quality of Cat LHD frames have been proven by our customers, many of whom reuse frames during machine rebuilds to get 2nd and 3rd lives out of their LHD's.
Hitch
Spread hitch design widens the distance between upper and lower hitch plates to distribute forces and increase bearing life. Thicker hitch plates reduce deflection. The wide opening provides easy service access. Upper and lower hitch pins pivot on roller bearings to distribute horizontal and vertical loads over a greater surface area. Shim adjusted preload reduces maintenance time. An on-board steering frame lock pin is fitted to prevent articulation during maintenance and service.
Sealed Pins
Sealed colleted pins are fitted to all bucket and lift arm hinge points for longer pin and bushing life. This reduces maintenance costs and extends service intervals. The sealed joints retain lubrication and prevent contaminant entry.
Z-bar Loader Linkage
Proven Z-bar loader linkage geometry generates powerful breakout force and an increased rack back angle for better bucket loading and material retention. Heavy duty steel lift arms with cast steel cross tube ensures extreme loads encountered during loading and tramming are efficiently dissipated for long service life.

Loader Bucket Systems
Buckets
Cat LHD buckets deliver unmatched productivity and structural reliability to help lower your cost-per-ton. Buckets are available in a range of sizes to suit most material types and densities.
Optional Wear Packages
Weld-on wear plates in high wear areas are standard. Additional wear packages, including sacrificial wear strips and Cat heel shrouds protect the edges from damage and reduce the need for costly bucket rebuilds.
Bucket Selection
Cat underground loader buckets are available in two styles to meet a range of loading, hauling and dumping conditions.
Dump buckets
Ejector buckets
Optional Cutting Edges
Cat half arrow and cast half arrow cutting edges extend bucket life in high wear applications. Additional GET option is the Cat weld-on GET. Available weld-on GET offers more wear material to maximize system wear life and bucket protection. Downtime is also reduced by an even wear rate between corners and edge segments, allowing both to be replaced at the same time.
