The Type A Four Wheel Bridge Crane 4WBC is a collapsible unit intended for measuring discharge or for sediment sampling from bridges. The 4WBC can deploy Columbus weights and sediment samplers up to 70 kg.
The crane is made from structural aluminum and stainless steel material. It includes a winch mount to accommodate the WS250, and WS400 sounding winch (optional) as well as the USGS type A reel. It is simple to put up and folds down into a compact sized package for transit.
The Type A Bridge Crane consists of two maneuverable wheels with manual brake and two fixed wheels that are fitted to the base, as well as all the necessary supporting chassis components. When in use, the crane is set up in full open position and the crane rests against the bridge railing with the boom arm been extended 1 metre out over the river. The optional counter weights are used as a cantilever to provide stability when the crane is in contact with the handrail.
