Excavator PC200-5 PC400-7/8 hydraulic arm cylinder for Komatsu

Excavator PC200-5 PC400-7/8 hydraulic arm cylinder for Komatsu

1. Boom: The long, vertical arm of the excavator that extends upward and outward.

2. Stick (or Arm): The part that connects the boom to the bucket or attachment, allowing it to extend and retract.

3. Bucket: The attachment at the end of the stick used for digging and scooping.

Overview

Working Principle

Hydraulic oil under pressure enters the cylinder barrel and pushes the piston. The piston rod then extends or retracts, generating movement and digging force.

Hydraulic force equation:

$F = P \times A$

Where:

$F$ = output force
$P$ = hydraulic pressure
$A$ = effective piston area

Higher pressure and larger piston area produce greater output force.

Basic Structure

An excavator hydraulic cylinder generally includes:

Cylinder barrel
Piston
Piston rod
Cylinder head
Guide sleeve
Sealing system
Hydraulic ports
Buffer mechanism

Applications

Excavator hydraulic cylinders are widely used in:

Crawler excavators
Wheel excavators
Mini excavators
Mining machinery
Construction equipment
