发明名称 Mobile support device for concrete-spreading hoses
摘要 A mobile support device for supporting a concrete-spreading hose includes a single piece support structure formed of rigid metal and including a pair of wheel attachment members and a central U-shaped hose supporting member. Longitudinally offset caster wheel assemblies are secured to the wheel support members. The U-shaped hose supporting member supports a concrete-spreading hose therein and extends downwardly below the rotational axes of the caster wheel assemblies thereby imparting a stabilizing low center of gravity to the mobile support device. A keeper element releasably locks the supported concrete-spreading hose in the U-shaped hose supporting member, and handle engaging elements on the mobile support device facilitates manual movement thereof by a worker manipulated hand tool.
