April 11 – With the strong support from CHINAHEAVYLIFT SPMT, our client Guangdong LIFT Engineering Machinery Co.,Ltd(GPEC) was contracted by Wuchang Shipbuilding Industry to transport 3,200t giant bridge section roll-on to barge for Hong Kong-Zhuhai-Macau Bridge project in Zhongshan city, Guangdong province.

This giant bridge section, which total weighed 3,200 tonnes and had the dimensions 132.6 m x 33.1 m, were transported from the fabrication facility yard to the barge by using total 100-axle lines SPMT. So, how to move this giant steel structure onto the barge safely and accurately? As there’s over 20m distance from the bridge section and barge, crane is not suitable for this project. Based on the analysis of actual situation, our client GPEC choose the better solution of CHINAHEAVYLIFT S2.43 Self Propelled Modular Transporters (SPMT), which is more cost-effective and easier to operate.

Detail CHINAHEAVYLIFT SPMT transport system configuration:

100 axle lines S2.43 SPMT (10 units – 6 lines module, 10 units – 4 lines module) compose 4 big SPMT module
4 PPU (390kw Mercedes Benz engine for Power Pack Unit)
1 Wireless Remote control

Normally it will take 5-6 hours to roll-on, but in this project, we need complete the whole process in 2 hours as the reason of Tidal influence. Also, high precision is essential for roll-on, deviation is controlled smaller than 5mm in every 100m movement. This requires everyone and every steps close-cooperation and no mistake permitted.

The most difficult is, when SPMT move onto the barge, the barge will swing and tilt with the change of weight. So how to keep balance? Thanks to the hydraulic steady system of CHINAHEAVYLIFT SPMT, which adopt reliable Germany brand main components and have hydraulic compensation stroke of approx. 700mm (±350mm). Hydraulic support cylinder on suspension is connected to each other by steel pipes and hose. With a cut-off valve (ball valve) for grouping the hydraulic cylinder. Support system is set to three hydraulic group according to cargo weight, center of gravity location and road conditions. This ensures a uniform axle load in Uneven road when traveling. Besides, the barge is equiped with pressurized cabin to outward drainage to ensure the balance.

Through two hours efforts, CHINAHEAVYLIFT SPMT successfully assist the 3200t giant bridge section roll-onto the barge, this is the first step of HZMB CB02 project, one historic move in Chinese Bridge Construction area. But For CHINAHEAVYLIFT, just another case with SPMT.
