Two Alimak SC 45/30 construction hoists were utilized in the pier construction of Wenzhou Oujiang North Bridge crossing the Oujiang river in Wenzhou City, Zhejiang province, China. The Alimak hoists provided efficient vertical access for both people and materials.
Two Alimak SC 45/30 passenger and material hoists were used during the construction of the bridge pylons at Wenzhou City, Zhejiang, China. With a payload capacity of 2,000 kg and a lifting height of 150 meters, and with 1.5 degree inclination with the pylones, the hoists provided efficient vertical access during the concrete slipform construction of the bridge pylones.
The bridge is a double-deck suspension bridge with three concrete pylons and with the main spans of 2 X 800 m. Both the upper and lower decks of the bridge are designed to carry 6-lane highways.
Alimak construction hoists have been used for over 50 years in all types of applications around the world. The standard range of Alimak construction hoists offer the optimum transport solution during slipform construction of towers, bridges, buildings and dams. It performs well with inclinations and curves and follows the constantly changing structures during construction.

Owned by China’s National Energy Investment Group, the Guodian Suqian Power Plant Units 3 and 4 (660 MW) are not only part of a supercritical secondary reheating unit project but are also involved in a project to develop large units and suppress smaller ones. The Ministry of Science and Technology of China listed it as a science and technology demonstration project.
As such, the Guodian Suqian Power Plant opted for an Alimak SL Rack and Pinion elevator for units 3 and 4. This industrial elevator provides ease of access for both passengers and goods weighing up to 600 kg, between the ground level and another two floors. This Alimak elevator solution required minimum preparation in the facility as rack and pinion elevators do not require a costly elevator shaft or machine room to be integrated into the facility structure prior to installation. Each of the tie-ins used to attach the elevator mast tower are fixed to the concrete by chemical bolts. The elevator can, therefore, be installed easily and efficiently. The purpose of the industrial elevator for this chimney application is to transport people to the CEMS (Continuous Emission Monitoring System) to measure emissions.
