UNDERGROUND LOAD AND HAUL
This acquisition followed the September 2015 announcement of CUGM acquiring the intellectual property of underground articulated truck designs from Specialised Vehicle Solutions ( SVS ). The new Cat ® AD22 is derived from the SVS UAT designs and is currently undergoing field trials .
The new Cat R1700K underground LHD features multiple engine configurations , a new ergonomic operator cabin and greater payload . The compact profile , efficient power train and rugged construction deliver low cost truck loading and LHD production .
The unit delivers a payload of 15 t , 20 % more than the previous model and supporting efficient three-pass loading of the 45 t Cat AD45B underground truck . After rigorous field testing is completed this year , the R1700K will be commercially launched in 2018 .
To enable optimisation of the new loader for lowest total costs in a specific application , multiple engine configurations are available . All options use the proven Cat C13 ACERT™ engine . This engine can be configured for applications that require compliance with the highest emission standards in underground applications , and it enables options for customers who are striving to improve underground air quality .
The R1700K is available in US EPA Tier 4
Caterpillar ’ s new AD22 truck is available with an open operator compartment or an optional enclosed cab . Both are ROPS / FOPS certified .
The sweeping deck design provides good sight lines around the front of the truck , and the LCD screen shows the rear-view camera view when backing
Final / EU Stage IV and in Tier 3 / Stage III emissions compliance configurations . The Tier 4 / Stage IV engine employs the Cat Clean Emissions Module , proven in millions of operating hours on a broad range of Cat equipment . The exhaust after-treatment package components include a diesel particulate filter and a selective catalytic reduction catalyst to reduce both particulate and NOx emissions to near zero . The R1700K C13 Tier 4 Final engine has a gross engine power rating of 257 kW at 2,050 rpm .
For Tier 3 / Stage III machines , Caterpillar offers the Ventilation Reduction Package , which uses select engine hardware and software modifications to minimise particulate matter
The new Cat R1700K tramming emissions . Further particulate reductions are available through the addition of an optional diesel particulate filter , which features automatic regeneration while the machine is working .
The R1700K operator cabin is designed to promote safe and efficient operation throughout the shift . An open ROPS / FOPS cab and an enclosed cabin are available . Increased leg room , multiple ergonomic adjustments , and automatic climate control and filtered ventilation in the enclosed cab enable operators to work comfortably .
Simple and easy-to-use controls are at the operator ’ s fingertips . Pilot hydraulic controls enable precise operation with low effort . Switches and control panels are located central to the operator and within arm ’ s reach for fast adjustment to the operation of the machine or systems . The R1700K provides enhanced visibility with an optional rearview camera that displays its view on the easy-to-read colour LCD monitor .
The monitor also presents live diagnostic code feedback for faster repairs in the event of an issue . The diagnostic codes refer to individual circuits or functions that have been monitored to display irregularities – enabling technicians to identify causes quickly .
The R1700K has many new features — ranging from simple to high tech . At the business end of the machine , the newly designed bucket has an increased throat angle to allow for faster filling
