Support design for base of concrete unit mast - with formed outrigger stored facing forwards on pump trailer

摘要

The mast may be used for delivery of concrete to elevated sites. The portable platform (2) which supports the concrete pump mast (4) has support members (5,6) which are swung out, and telescopically extended. The point of rotation (7) for the forward support is immediately in front of the point for the real support. The forward support is stored in a position facing forwards in the direction of travel. USE/ADVANTAGE - Design of support system for base of concrete delivery mast allows outriggers to be deployed on confined sites.
