Abstract

An operator's seat for heavy equipment having optimized switch arrangements for controlling the equipment is provided, in which arrangements of various kinds of switches and components of operating devices that are frequently used by an operator in the seat due to the characteristic of the equipment are integrated within a radius that an operator's hand reaches (i.e. in a hand arm operation zone), and thus physical inconvenience and fatigue that the operator who repeatedly operates working devices for a long time suffers can be reduced. The operator's seat for heavy equipment includes a switch instrument installed within a radius that a hand of an operator sitting in the operator's seat reaches, a control lever mounted on a specified position of the switch instrument to control operations of working devices, and switches arranged on the switch instrument in closest proximity to the control lever so that the operator in the operator's seat can operate the switches in the closest position in which the operator does not invade a control stroke zone of the control lever.
