The Right Hand Mirror was developed by the US Bureau of Mines as part of a research project aimed at increasing visibility around   large mobile vehicles. Unlike most competitive mirrors which were designed for stationary applications and later adapted for mining use, the Right Hand Mirror underwent five years of development specifically for mining applications and is now in use worldwide.

 

This unique mirror is a RECTANGULAR CONVEX unit measuring 503mm x 302mm, with spherical radius of 30°. The rectangular shape gives the optimum view configuration with a compact shape for mirror protection. Angles of view are approximately 70° vertical and 48° horizontal, which are about 100% wider than typical 305mm circular convex mirrors.

 

The mirror lens is housed in a rugged, heavy duty steel frame which features a 1cm solid steel overhanging lip to protect the lens from rock fall breakage. The lens is mounted in rubber to absorb vibrations and shock.

 

The lens is made from tempered (heat toughened), scratch free safety glass.

 

The Right Hand Mirror gives the driver the ability to sight, at the one time, the top of the load bed to below the back wheel contact point. To obtain a similar field of view a circular lens would have to be at least TWICE as wide as the Right Hand Mirror to give the same effect. Once installed the field of view and image characteristics of the mirrors are such that individual driver adjustment is not required.

Right Hand Mirror Field of Vision

 

 

 

 The Right Hand Mirror overcomes several serious shortcomings in all traditional large vehicle mirrors.

 

For example;

  • Traditional "convex" mirrors are unsatisfactory because they exhibit unacceptable levels of disrtortion, particularly near the edges of the mirror

  • Traditional "convex" mirrors exhibit unacceptable perspectives in relation to distance and field of view

Specifications
Size - 503mm x 302mm
Type - Toughened Glass
Thickness - 6mm
Frame - Powder Coated Steel (2mm)
Mounting - Neoprene Rubber
Weight - 12kg

 

Features
  • The unit is constructed so as not to become a potential noise source as do some of the lighter variety industrial mirrors
  • Compared to other available mirrors, Right Hand Mirrors provide the optimum in reliability, decreased accident potential and increased productivity
  • While the Right Hand Mirror is the best mirror available for off-road DUMP TRUCK applications, it is also being effectively used on a variety of SHOVELS, DRAGLINES, SCRAPERS and LOADERS, together with any mobile application where rugged, compact visibility improvement is required

Mounting Clutch Assembly1.png

As an optional extra, the Right Hand  Mirror can be mounted using a heavy duty steel mounting post. This assembly includes a friction mounted clutch which allows the mirror to swing towards the mobile plant, should an obstruction be encounted.

Should a lens breakage occur, replacement is simple and quick.
