A hydraulic manifold is provided on a primary mast section which maximizes the commonalty of hydraulic components used in the hydraulic lift control systems of two and three stage mast assemblies used in lift trucks. Two and three stage mast assemblies are illustrated using primary mast sections which are identical and using secondary mast sections which are nearly the same.

A hose tensioning device is provided to suitably tension a flexible hydraulic hose used on a lift truck so as to reduce damage that might otherwise occur should the hose become slack. The hose tensioning device serves as a hydraulic connector and its outer component is a protective housing for the biasing spring by which the hose is tensioned.
