The Lingdingyang Bridge, Shenzhong Link, Guangdong, China
The Lingdingyang Bridge is part of the Shenzhen-Zhongshan Link (also referred to as "Shenzhong Link"), located in the Chinese province of Guangdong, in the Pearl River Delta downstream of Guangzhou city. The link consists of a series of bridges and tunnels connecting the cities of Zhongshan in the western side of the delta and Shenzhen in the eastern side of the delta, it is located approximately 27km downstream of the Humen Bridge and 32km north of the Hong Kong–Zhuhai–Macau Bridge.
The Lindingyangd Bridge is a suspension bridge with a main span of 1666m and two side spans of 500m. The towers are approximately 270m tall. The cable suspension system supporting the deck consists of a pair of 1.066m nominal diameter PPWS cables aligned in parallel at 42.1m separation, with cable bands and vertical suspenders at 12.8m longitudinal centres. The deck is an aerofoil shaped orthotropic steel box 49.7m wide and 4.0m deep, fabricated in sections up to 12.8m long weighing up to 400t.
DLT were sub-contractors to Guangdong Provincial Changda Highway Engineering Co for the retrofit design of the 500t capacity deck lifting gantries used in the Humen II Suspension Bridge project. A total of 2 No. retrofitted gantries were used for deck erection: one on the west side span and one on the western half of the main span.

The gantries were erected onto the main cables adjacent to the towers using the site tower cranes.:
The retrofit required the development of an innovative solution using nylon ramps with supporting steelwork for the wheels to roll over cable bands with horizontal bolts:
