Cat unveils new underground loader

Caterpillar has released its new R1700K underground loader at MINExpo.

The loader features a number of engine configurations, ergonomic cabin, and a greater payload capacity, helping operators drive down costs while lifting productivity.

The new machine has a payload of 15 tonnes, 20 per cent more than previous models, and complements the 45 tonne Cat AD45B underground truck with a three pass loading support.

To enable miners to optimise the new loader for lowest total costs in a specific application, multiple engine configurations are available.

All options use the Cat C13 ACERT engine which can be configured for applications that require compliance with the highest emission standards in underground applications, and enables options for customers who are striving to improve underground air quality.

The R1700K is available in US EPA Tier 4 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 close to  zero.

The R1700K C13 Tier 4 Final engine has a gross engine power rating of 257 kW (345 hp) at 2050 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 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 loader’s cabin is designed to promote safe and efficient operation throughout the shift, and is available in both open ROPS/FOPS cab and an enclosed cabin.

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 color LCD monitor.

The monitor also presents live diagnostic data 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.

It features newly designed bucket has an increased throat angle to allow for faster filling and better material retention during tramming.

New Cat Bolt On GET are designed for use in abrasive applications where high wear rates make welded GET impractical.

Built-in wear indicators and replacement corner segments allow the system to be integrated into scheduled maintenance regimens.

The traction control system enables the R1700K to control drive power to each wheel independently, resulting in minimal tyre slip, optimum traction, and the ability to penetrate the pile more effectively for fast loading.

It is equipped with multiple subsystems for fast technology implementation. The Cat line-of-sight remote control systems allow operators to control their machines from safe distances, and the Cat Command for underground, semi-autonomous system enables operators to work from a remote location. Remote machine health monitoring, payload monitoring and other technology options can be installed at the factory or in the field.

The R1700K will be launched in 2018 after field testing next year.
