MP250 struts use 610mm diameter tubular sections as the main structural member. At shorter spans, the hydraulic capacity limits the axial load and at longer spans, the potential for lateral buckling of the extension sections dictates overall axial capacity.
The MP250 has an practical operating range of 3.1m to 25.0m without intermediate support and can withstand working loads up to 250 tonnes at shorter spans. For higher load / longer span applications, it is possible to combine the MP250 hydraulic unit with 1220mm (super tube) diameter extension pieces, using appropriate adaptor pieces.
