• Specification

• Function 

1. Assisted Lifting & Holding of Heavy Movable Components
How it works: When the operator initiates opening (e.g., lifting a cabin door), the compressed gas in the cylinder pushes against the piston, generating an upward/opening force that offsets the weight of the panel. Once the panel is opened to a desired position, the gas spring’s pressure balances the panel’s weight exactly, holding it securely in place—no additional latches or supports are needed.

Why it matters: Komatsu cabin panels (e.g., reinforced steel doors) can be heavy; without a gas spring, operators would need to exert significant force to lift them, increasing fatigue or risk of injury (e.g., a panel slipping and falling). The gas spring makes opening/closing effortless and prevents accidental slamming.

2. Damping & Controlled Movement
How it works: As the piston rod extends or retracts, the gas is forced through small internal orifices in the piston. This creates gentle resistance that slows the movement of the attached panel (e.g., a cabin door closing slowly instead of slamming shut).

Why it matters: Sudden, uncontrolled movement (e.g., a heavy door slamming due to wind or operator error) can damage the door’s hinges, latches, or the cabin frame over time. Damping also improves operator comfort—no abrupt noises or jolts during daily use.
