Power wash the exterior windows with water when ambient temperatures are above freezing. To address this issue, Tigercat-branded polycarbonate window cleaner is now available to clean cab windows without the risk of chemical damage to the polycarbonate. However, even with this coating, it is relatively easy to scratch the surface when compared to glass which is incredibly resistant to a long list of cleaning chemicals. The surfaces of Tigercat polycarbonate cab windows are specially treated with a hard coating to provide enhanced resistance to abrasion and ultra-violet (UV) radiation. Polycarbonate windows provide a much tougher solution than glass but the thermoplastic material is sensitive to some common chemicals. Forestry harvesting applications can produce hazards from high velocity thrown objects such as wood chips, saw teeth or broken saw chain fragments.
Polycarbonate material is used to resist impact from large branches, falling tree tops, and to absorb high levels of energy. Polycarbonate windows used in Tigercat cabins range in thickness from 9-32 mm (0.375-1.25 in).
The thickness of the material used in a particular cab window is determined by a number of factors including the size of the window opening, the proximity to a safety hazard, the type and severity of the hazard, and the requirements of applicable safety standards. This material is a replacement for glass when improved toughness, strength, durability, and safety are required.
Most windows used in the operator’s stations of Tigercat machines are made from a polycarbonate thermoplastic resin.
