Dual drilling controls for DD422i and DD422ie

Sandvik has recently released a new Dual Controls package. This package is retrofitable on active DD422i and DD422iE.

Description

Sandvik DD422i And DD422iE face drills have introduced major improvements compare to the previous generation of drills. Particularly concerning the operator safety and usability with the new cabin design that brings drastically reduced noise levels, improved drilling visibility and the possibility to drill seated. Drilling performance and costs of drilling consumables are also greatly improved thanks to the torque optimized drilling control (approximately 10% improvement in productivity and nearly 20% improvement on drill consumable costs measured during field test, compare to previous generation hydraulic controlled jumbo).

In order to make these benefits available for ground support application, Sandvik has recently released a new Dual Controls package. This package is retrofitable on active DD422i and DD422iE.

Dual Drilling Controls improve fleet optimisation, versatility and performance for the Sandvik DD422i and Sandvik DD422iE face drills. The Dual Controls package was designed to address a wide range of needs identified by mining contractors currently using development drills for a variety of tasks including boring, bolting and meshing DD422i and DD422iE Dual Controls (DC) allows customer to use a single platform for all drilling applications.

Depending original machine configuration, the retrofit kit could require complete new cabin with Dual Drilling Controls, TFX feeds, hydraulic parallelism booms with hosing, electric system modification and software update,
Retrofit of Dual Drilling controls imply the removal of boom instrumentation and drilling automation.
Advantages

-Allowing to use the DD422i platform for a variety of manual tasks like boring, bolting and meshing.
-Allows to use only one drilling platform (DD422i) for all drilling application.
-Improved cabin, compare to previous hydraulic controlled jumbos.
-Torque optimized drilling controls system.
Customer values

-Increase versatility of the unit. This provides modular options for the boom and drilling assemblies, whilst the carrier and cabin remain standardized.
-Commonality in spare parts, service points and service principles with 400i series
-Compatibility with Sandvik digital systems, e.g. MySandvik and OptiMine
-Improve safety and usability by reduced noise level and improved comfort, ergonomic and visibility.
-Increase productivity by providing best possible drilling performance.
-Improve rock tools life.
