CONTROL CABIN SLEWING WITH THE HOIST
In this case the control cabin slews with the hoist to ensure optimum driver visibility on a scrap metal crane working in a series of hoppers.
TRIANGULATED REEVING
To obviate load swing on a magnet crane charging a furnace Street designed a special rope reeving with three live ropes and no bottom sheaves.
CANTILEVERED HOIST
To enable two different gauge lifting beams to be handled by one crane this special crane with two pairs of hoists was designed such that one pair is cantilevered outside the crane beams.
GRABBING HOIST
This twin hoist is designed for use with a mechanical grab. One hoist lifts and lowers the load and the other opens and closes the grab.
HEAVY DUTY FAST SPEEDS
High hoisting speeds and duty classification are essential on many process cranes, in such cases variable speed control and electrical braking can be specified.
