Mix of cranes

Mining Machinery Developments (MMD) multi-million pound factory expansion includes a mix of overhead travelling and jib cranes from Street Crane Company.

Three 20t overhead cranes in each of two new bays run on full-length free-standing 60m gantries. They are double girder box beam design and have infrared anti-collision systems so can safely operate on the same track.

For lifts to 40t, they may be used in tandem and weight distributed by spreader beam. The bays also have 10 x 1t jib cranes.

In the original factory buildings, Street has installed two double girder cranes of 50t and one of 25t.
