Abstract
An excavator operator cab (10) has an operator seat (12) and a control console (15) mounted beside the seat. A forward control stick (20) and a rear control stick (22) are positioned in the console (15) such that the rear control stick supports the arm of the operator while he grips the forward control stick. The forward and rear control sticks (20,22) are manipulated independently or in concert with one another.
Claims6
An excavator operator cab having an operator seat and a control console mounted beside said seat with a forward control stick positioned aside a forward portion of said seat and with a rear control stick positioned rearwardly of said forward control stick aside a mid-portion of said seat, said rear control stick having an arm pad mounted thereon at a height and distance relative to said forward control stick to enable an operator to grip said arm pad and manipulate said rear control stick with a forearm of the operator while simultaneously gripping and manipulating said forward control stick with a hand of the same arm while being seated on said seat and wherein a handle is mounted to an upper portion of said forward control stick and said arm pad is mounted to said rear control stick at a height lower than an uppermost portion of said handle whereby the hand and the forearm of the operator may simultaneously manipulate the control sticks along a generally level and ergonomically advantageous elevation relative to one another.
An excavator operator cab having an operator's seat, a control console mounted beside said seat, and a forward control stick and a rear control stick extending uprightly from said console and spaced-apart from one another a distance sufficient to enable an operator seated in said seat to operate said forward control stick with a hand and said rear control stick with a forearm of the same arm, said forward control stick including a handle extending outwardly from said console to a height greater than an uppermost point of said rear control stick whereby simultaneous operation of the control sticks with the hand and the forearm of the operator may be achieved with the forearm and the hand at an ergonomically level position to one another.
