Underhung Cranes – Underhung cranes are designed for loads up to 30 tons and offer certain advantages over the Top Running type crane. By suspending the bridge of the crane on the lower flange of the runway, it can safely handle material which is below and even beyond the runway. Virtually every cubic foot of space in an open bay area be reached to lift, carry, hold, position, stack, turn and set loads of all shapes, sizes and weights. Another major advantage of this type of crane is it can easily be designed to transfer loads between bays, between cranes or between cranes and monorails with the use of interlocks (Transfers).
