Hay crane (crane)
A Heukran serves for the storage and implementation of dry crop and bales in barns and barns . The hay crane replaced the labor-intensive hay elevator , unless it was replaced by a hay blower .
Most hay cranes are designed as suspended slewing cranes with telescopic arms or hall cranes, only individual hay cranes are designed as normal slewing cranes . In contrast to a single-rail hay elevator, a hay crane always runs on two rails, which can also be used to negotiate curves. The rails are either fastened under the ceiling of the building (suspension crane and overhead crane) or on the floor (slewing crane); hay excavators are almost always used instead of the latter .
Hay cranes are driven exclusively by electric motors.
While the hay elevator only facilitates the storage of dry goods (the dry goods must still be distributed by hand over the entire storage area after storage), the hay crane can not only store dry goods and bales over the entire storage area, but also pick them up again.
