Altec has developed a tilt cab option for all of its riding seat crane models. The new cab allows the operator to adjust the angle of the cab from 0 degrees to 20 degrees above horizontal, with hydraulic power, the company said. The new tilt cab will allow operators to have better vertical visibility and less neck strain during certain work applications, such as setting cross arms on transmission structures, the company said. Additionally, the tilt cab is located forward of the centerline of rotation, providing better horizontal visibility when rotating the crane clockwise. Altec is the first boom truck crane manufacture to offer a tilt cab option, the company claims.
