Beam Launcher

JQG series launching crane (hereinafter referred to as Launching Crane) is specially designed to lift concrete bridges, from various spans of T-shape highway girder, to various box-type and plate-type girder. It can be used for 4% longitudinal slope and over 450m radius curve girder.
Main structure of Launching Crane is of multi-section truss connection girder. It features easy disassembly, convenient removal at construction site, one time positioning of side girder, and strong wind resistance, which eliminates the trouble of manual removal of abutment and ensures safety. So, it is ideal crane model and loved by our honorable clients
