WebRamps can have one of the following configurations: (a) Straight run (fig. 1); (b) 90 turn (fig. 2); (c) Switch back or 180 turn (fig. 3). 3.3 Width Width varies according to use, configuration... Web10 May 2015 · Double benching (or triple benching) is used where the inter-ramp slopes angles are steep enough that single benching would result in an overly flatten slope. For example if the inter-ramp slope is 50° and the BFA is 70°, then the corresponding calculated catch bench width for a 5m high bench would be 2.4 metres. Web1.
