Product Description

Doosan Excavator Control handle Joystick Handle Assy DH-7 Pilot Control Lever Excavator Machinery Parts

The excavator joystick is in essence a proportional hydraulic pilot control valve. It does not directly power excavator motions but transmits control‑purpose hydraulic oil to activate the main multi‑way valve, controlling the speed and direction of machine movements. Positioned on the left and right within the operator cabin, the control lever (also referred to as pilot control lever, hydraulic lever or joystick) serves as the core operating element for all excavator functions, functioning as the machine’s “steering wheel and limbs”.

Operation Method

All excavator operations are controlled via multidirectional tilting of the joystick:

Boom (main arm) lifting
Stick (secondary arm) extension and retraction
Bucket opening and closing
Left‑right upper‑structure slewing
Combined control with foot pedal valves for traveling

Operating Principle

Each handle houses an integrated hydraulic pilot valve:

Pushing the handle displaces the internal spool
Low‑pressure hydraulic control signal is produced
Main hydraulic multi‑way valve is actuated
Cylinders and motors execute actions with adjustable speed and direction

Proportional Speed Regulation

Greater handle tilt angle expands spool opening → elevates output pilot pressure → increases main valve opening → accelerates boom, stick, bucket and slewing movements. After releasing the handle, return springs restore the handle and spool to neutral, cutting the pilot oil circuit, releasing pressure, resetting the main valve, and instantly stopping all motions.
