Features
Pre-Installation Safety Checks
Track Authority Verification
Confirm work order/possession with dispatcher
Verify power isolation on electrified tracks (minimum 3-point check)
Clamp Inspection
Check for:
Jaw wear >3mm
Bolt thread damage
Cracks in stress areas
Corrosion >25% of surface
Reject any clamp failing visual inspection
Environmental Assessment
Measure rail temperature (thermal expansion calculations)
Check for ice/snow accumulation
Verify daylight/visibility conditions
Installation Safety Protocols
Personal Protective Equipment
Hard hat
EN 166 eye protection
Cut-resistant gloves (Level 4)
Steel-toe boots
High-visibility Class 3 vest
Tool Safety
Use calibrated torque wrenches (certified within 6 months)
Maintain 1.5m clearance from moving parts
Never modify clamp components in field
Secure tools when trains approach
Speed Restrictions
Standard clamps: 40 km/h (25 mph) max
Heavy-duty clamps: 25 km/h (15 mph) max
Post visible signage 200m each side
Inspection Schedule
First 2 hours: Check every 30 minutes
Next 6 hours: Hourly inspections
Thereafter: Every 4 hours
Critical Inspection Points
Bolt tension (retorque if >10% loss)
Rail alignment (max 3mm deviation)
Jaw contact (no visible gaps)
Crack formation
Clamp Removal Safety
Verification Requirements
Confirm permanent repair completion
Obtain track engineer approval
Check replacement joint certification
Removal Process
Gradually release tension (alternating bolts)
Inspect rail ends after removal
Tag damaged clamps for repair
Post-Removal
Conduct ultrasonic rail testing
Verify track geometry
Remove speed restrictions gradually
