Subject: approach table The mobile crane then lifted the 40 tonne concrete sections one after the other so that the vertical load towers could be lowered by about 20 cm before the concrete sections were lowered by this amount, moved out sideways and dropped onto the low loader ready below (Fig 1). Working this way, each day four concrete sections were removed, loaded and disposed of. After four days a stretch of more than 100 m of the approach table had been completely removed.Что такое (approach table)? Это наверняка не (подводящий рольганг). |
