Product Specifications

Technical details and manufacturing context for Carrier/Undercarriage

Definition
The carrier/undercarriage is the foundational mobile platform of a wind turbine installation crane, designed to support the crane's superstructure while enabling transportation and positioning on various terrains. It typically includes crawler tracks or wheels, power transmission systems, and structural frames that distribute the crane's weight and provide stability during lifting operations.
Working Principle
The undercarriage transfers the crane's load to the ground through crawler tracks or wheels, with hydraulic or mechanical systems enabling movement and steering. It incorporates outriggers or stabilizers that extend to create a wider base during lifting operations, preventing tipping and ensuring safe load handling.

Application Fit & Sizing Matrix

Operational Limits
pressure: N/A (structural load-bearing component)
other spec: Ground pressure: 5-15 psi, Max slope: 5° operational / 10° transport, Wind resistance: 20 m/s operational / 30 m/s parked
temperature: -20°C to +40°C (operational), -30°C to +50°C (storage)
Media Compatibility
✓ Firm compacted soils ✓ Graded construction sites ✓ Stabilized gravel pads
Unsuitable: Unprepared soft/marshy terrain without ground reinforcement
Sizing Data Required
  • Maximum crane load capacity (tons)
  • Required ground bearing pressure (psi/bar)
  • Site terrain conditions and slope requirements (°)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Track link pin and bushing wear
Cause: Abrasive soil ingress and inadequate lubrication leading to accelerated metal-on-metal contact and clearance increase
Roller and idler bearing failure
Cause: Contamination from dirt/debris penetration through worn seals, combined with improper track tension causing excessive radial loads
Maintenance Indicators
  • Excessive track sag (more than 2 inches between top of track and carrier frame when measured at mid-span)
  • Audible metallic grinding or clicking noises during operation, especially when turning
Engineering Tips
  • Implement regular track tension adjustments according to manufacturer specifications using proper measurement tools - avoid overtightening which accelerates component wear
  • Establish aggressive contamination control through daily track cleaning and scheduled undercarriage washdowns, combined with frequent lubrication of pins/bushings per operating hours

Compliance & Manufacturing Standards

Reference Standards
ISO 286-2:2010 (Limits and fits) ANSI/ASME B18.2.1 (Square and Hex Bolts and Screws) DIN 15061-1 (Components for cranes - Underframes)
Manufacturing Precision
