While concreting of bridges bring unique challenges, various advanced concreting equipment and solutions can help overcome the same. KYB-Conmat offers products for bridge construction, such as concrete pumps, mobile concrete batching plants, rack and pinion elevators, stationary concrete batching plants, tower concrete plants, transit mixers and bridge deck pavers.
That said, Premraj Keshyep, Managing Director, KYB-Conmat, highlights the reasons that make concreting of bridges more challenging than normal concreting jobs:
- Being part of the road/rail network, bridges are generally spread over a larger geographical area and, hence, concrete supply to the work site is a challenge. Also, bridges require high-performance concrete to be delivered to these remote sites. KYB-Conmat manufactures high-performance transit mixers for this purpose and offers the same in 6/7/8 cu m capacity, both with a separate engine and PTO drive.
- Considering the height of the bridge deck from the ground, it is always challenging to deliver concrete to the desired work height. The company manufactures S Valve-type concrete pumps for this purpose, which can pump high-performance concrete up to the height of 100-150 m.
- In case of extra high bridges in hilly regions suspension or cantilever bridges where bridge columns are extremely high, it is difficult to access the column for various construction jobs. We manufacture a specially designed rack and pinion elevator for this purpose. These elevators do not require a machine room and can be extended vertically simultaneous to the raising height of the bridge columns. These are extremely safe owing to a three-point safety system and fall-safe device, and come in various size and load capacities, from 1-3 tonne, and can carry men and materials to desired height.
- Paving the bridge deck is even more challenging as the equipment needs to be light while offering the desired compaction essential for durability of the road surface. We manufacture a compact and modular concrete bridge deck paving machine that weighs just 2/3 tonne and can pave the bridge deck from 3 m to 30 m width.
