QUIETER CABINS FOR ADDED OPERATOR COMFORT

The comfort and health of our equipment’s operators is paramount for Sandvik Mining, which is why we are focusing on ways to reduce noise levels within the cabins of our equipment. The progress we are making in this area is resulting in a healthier and more comfortable working environment for the operator.

Below are two examples of our equipment and a description of their cabins’ properties

SANDVIK LHD (LOAD, HAUL, DUMP) AND DUMP TRUCK CABINS

Noise suppression and vibration reduction for Sandvik LHD (Load, Haul, Dump) and dump truck cabins

Not only do the Sandvik LHD and dump trucks offer high productivity but they can also be equipped with comfortable enclosed cabins that supress noise and dampen vibrations.

Noise levels inside these cabins remains below 80 dB (A)*, which means the operator can enjoy working in a quieter environment. Harmful vibrations are also reduced as the cabin is installed on rubber pads instead of solid mounting on the machine. The operator’s seat also has suspension fitted which reduces the experience of vibrations further.

In addition to these benefits, the cabins, when fully closed, are pressurized in a way that restricts dust entering from the outside. They also have a climate control functionality which maintains cabin temperature at the desired level, with filtered air (5μm particles or larger) entering and circulating within the space

SANDVIK DR461i DRILL RIG

Quietest cabin of the drill rigs created - the Sandvik DR461i

When Sandvik Mining designed the first of its new-generation rotary blasthole drills, it ranked performance and operator ergonomics as the most important criteria in order to ensure the machine performed even in extreme conditions.

"Our ambition from the start was to deliver maximum peace of mind to the owner," says Ken Stapylton, Vice President Surface and Exploration, Sandvik Mining. "Rugged though the new machine is, our concern has been to pay a lot of attention to operator ergonomics as well as create a layout that makes service and maintenance as simple as possible."

The DR461i’s FOPS-certified cabin includes "all in the seat" drilling and tramming controls and touch screens. The cab is pressurized and sound insulated to 80 dB(A)* or less. It is air conditioned, with tinted windows that are angled to reduce glare, and a "safari roof" to keep it cooler.

"Operators tend to work 12-hour shifts. So it's vital we make life as comfortable as possible for them," Stapylton says. Tim Thiel, Barrick Gold driller and one of the primary operators on the prototype, approved. "I've had a lot of people that have come in while I've been drilling and complimented how quiet the cab is. It's almost like comforts of home. You spend a large amount of time in it. When I get to shut that door, it's nice and quiet. You don't have to hear the motor rumbling in your ear."

*dB (A)

A-Weighted decibels, abbreviated here as dB (A), is the most common weighting scale that is used in noise measurement. It follows the frequency sensitivity of the human ear at low levels and is a good predictor of damage risk to the ear. A-Weighting scaled sound meters filter out low-frequency noise that they measure, which is similar to the response of the human ear.
