A seat (3) for heavy equipment having a buffer means in forward and backward directions is provided, which can protect an operator by attenuating impact and vibration generated in a cab in forward and backward directions of an excavator in accordance with the driving of the buffer means in a main working mode of the excavator. The seat for heavy equipment is mounted on a suspension plate and is located between left and right console boxes (5,6). The seat for heavy equipment includes a lower member mounted on the suspension plate; an upper member slidably mounted on the lower member in forward and backward directions of the equipment; a buffer means for attenuating impact and vibration generated in the forward and backward directions of the equipment; a tilting means including a frame (25), a hinge shaft, a driving shaft (27), and a control handle; and a locking means for locking and unlocking forward and backward movement of the upper member (11) against the lower member (10) when a pusher installed on one side of the frame (25) is manipulated. In a main working mode of the equipment, a buffer function is performed through forward and backward movement of the upper member (11) against the lower member (10), and when the main working mode is released, the buffer function is released.
