Abstract:

Evaluation tests of three pieces of equipment for use with an elevated causeway are reported. Each test is presented and discussed separately. The equipment evaluated includes two systems for lifting pontoons on piles - a hydraulic jacking system and block and tackle hoist system with Griphoist hand jacks - and explosive pile cutters. In general, the findings are the hydraulic lift system proved to be too complex and unreliable the block and tackle gear is marginally safe the inside inflatable cutter satisfies more of the operational requirements than does either of the other two cutters.
