Tanguey Operator
Problem
The position and size of the monitor caused the operator to have excessive neck flexion (looking down) as the monitor was placed on a box on the floor of the cab and was difficult to view. Over time this can cause strain and stress to the neck, shoulders and upper back. There was also a problem with glare coming in the windows when the operator was trying to view the monitor. Over time this can cause strain and stress to the eyes and neck muscles.
Recommendations/Solution
A flat screen monitor was installed. This monitor can be adjusted for the height, angle and distance, allowing operators to adjust it to their individual preference and helping reduce the glare when necessary. The ideal location for a monitor is 18 to 24 inches from the operator’s face. If the monitor cannot be placed in that range because it obstructs the operator’s |

| view, it’s important to ensure that the screen is large enough that the screen is large enough to see all necessary information. When possible, the monitor should be 2 to 3 inches below the eye level of the operator, should have no more then a 30-degree lateral angle and must not obstruct the operator’s view. The best location for the monitor is in front of the operator, but if this can’t be done the monitor may have to be placed on the left or right side. In most cases the operators will find it more comfortable on the left side, as we are accustomed to looking to the left first when reading. There are two different options for addressing glare problems: tinting the lexan glass or providing an anti-glare cover on the monitor. The flat screen also takes up less space and produces less heat in the cab.
Other Applications in Forestry
Anywhere there are monitors to view.
