Manually operated hydraulic shoring systems for groundwork support - Assessment by calculation or test Ingestion-build-71203 The provisions of BS 4183What is BS EN 14653 2 hydraulic shoring systems assessment? Hydraulic shores prevent cave ins by supporting the side walls of a trench by means of hydraulic pressure. BS EN 14653 is a European standard series applicable to manually operated hydraulic shoring systems for groundwork support. BS EN 14653 2 is the second part of the multi series, and specifies methods of calculation and test to assess the conformity of manually operated hydraulic systems
