What Mechanical Components Are Mainly Upgraded in Escalator Modernization?
As the service life of an escalator increases, its mechanical structure gradually suffers from wear, aging, and even potential safety risks. To ensure safe and stable operation, improve riding comfort, and extend service life, Escalator Mechanical Modernization is a crucial process during old escalator upgrades. So, which mechanical components are typically prioritized in modernization? Below are the core parts most commonly upgraded.
1. Drive System
The drive system is one of the key components powering the escalator. Worn-out drive units can cause insufficient power, increased noise, or slipping issues. Modernization may include:
Replacing drive sprockets or main shafts
Replacing gear reducers or the complete drive unit
Optimizing transmission efficiency
Upgrade Benefits: Enhanced power output, lower energy consumption, and reduced maintenance cost.
2. Main Chains (Step Chain & Drive Chain)
Main chains operate under heavy load and constant motion, making them highly prone to wear and fatigue. During modernization, it is critical to inspect:
Chain elongation
Loose chain links
Corrosion conditions
Wear or deformation of chain sprockets
Using A-FLY high-strength wear-resistant step chains can significantly improve operational safety.
3. Step System
Worn or damaged steps and rollers pose direct safety risks to passengers:
Replace step treads
Replace step rollers
Check step alignment and clearance
Upgrade Result: Smoother operation and lower noise levels.
4. Handrail System
Includes:
Handrail guide wheels/support rollers
Drive wheels & tensioning devices
Long-term use can lead to slippage, cracking, or misalignment. Modernization improves durability and handrail grip comfort.
5. Comb Plate System
Damaged comb plates or excessive gaps may cause shoes or clothing to get trapped:
Replace comb plates
Check and adjust step-to-comb clearance
Upgrade Purpose: Enhanced passenger safety at entry and exit zones.
6. Guide Rail System
Guide rails affect the trajectory of step movement. If worn, they can cause vibration and noise:
Replace step rails
Replace handrail guide rails or adjust parallel alignment
Upgrade Effect: Improved operational smoothness and mechanical longevity.
7. Braking System
Aging brakes are a major safety concern and must be upgraded:
Replace main brake
Inspect brake linings and braking clearance
Ensures reliable stopping in emergency situations.
