Client Background

WindPower Energy was constructing a 200MW wind farm in Ulanqab, Inner Mongolia. They needed to transport 36 wind turbine blades (78 meters each) from Tianjin Port to the project site, a distance of 600 km through mountainous terrain and rural roads.

Key Challenges

Oversized cargo: Each blade was 78 meters long, 4.2 meters wide, and weighed 25 tons — far exceeding standard transport dimensions

Route obstacles:

Time window: All 36 blades needed to arrive within 45 days to meet the construction timeline before winter
Permit requirements: Oversized transport permits were needed across 3 provinces (Tianjin, Hebei, Inner Mongolia) with varying regulations

الحل

Solution Overview

Meicheng engineered a complete heavy-haul transport solution including route survey, bridge reinforcement, multi-province permitting, and specialized blade-transport trailers with police escort.

Key Actions

Route survey and engineering: Conducted a 5-day route survey identifying 23 restricted bridges, 8 narrow village roads, and 12 critical turns; designed bypass routes and reinforcement plans
Bridge reinforcement: Installed temporary steel support structures on 7 bridges that could not support 25-ton axle loads
Multi-province permits: Obtained oversized transport permits from Tianjin, Hebei, and Inner Mongolia transport authorities within 15 days
Specialized trailers: Deployed 3 blade-transport extendable trailers (up to 80m) with hydraulic steering for tight turns and 360-degree blade rotation capability
Police escort and traffic control: Coordinated with local traffic police for escort vehicles at all 12 critical turns and 8 village passages
Convoy scheduling: Transported blades in convoys of 3, with each convoy departing at night to minimize traffic disruption

النتائج

Results

All 36 blades delivered in 38 days, 7 days ahead of the 45-day deadline
Zero damage to any blade during the 600 km transport
All 7 reinforced bridges passed inspection with no structural issues
Zero accidents or traffic incidents across 12 convoys through 3 provinces

The wind farm was commissioned on schedule in November, generating 200MW of renewable energy. WindPower Energy has since contracted Meicheng for 2 additional wind farm projects in Hebei and Gansu.
