OVERHEAD CRANES
Single Girder Overhead Crane
The single girder type is the most common overhead crane. It is generally used for light applications normally up to 10 tons.
-
In some special cases the capacity could go up to 20 tons
-
Maximum range of 100 feet
-
Hoist suspended from bridge beam
Double Girder Overhead Crane
The double girder overhead crane structure is used for heavier applications up to 125 tons and reaching over 100 feet of span. It can also be used to gain lifting height because the hoist of the double girder overhead crane is placed on the beams and the hook fits between them.
Box Girder Overhead Crane
Box-type beams are custom-made for large capacities and large spans when W-type beams are no longer sufficient.
Top or Under Running Overhead Crane
Suspended (Under Running) – The rails of a suspended overhead crane are installed in the ceiling of the building, so there is no need for columns, leaving the floor free of obstacles. However, for the same reason, the capacity of this type of crane is limited.
Mounted (Top Running) – The deck is placed on rails and achieves greater capacity than the suspended type because the rails are installed on the columns of the building or self-supporting structure.
Manual or Motorized Overhead Crane
Small workstations are generally “Manual” moving. However, in order to offer better control, it is recommended to install the “Motorized” type workstation when loads exceed 2 tons.
Custom Fabrication Overhead Crane
We manufacture your overhead crane according to your dimensions, needs, and specifications.
-
Service platform with lighting
-
Explosive environment (anti-spark materials such as copper, explosion-proof cabinet)
-
Dusty Environment (insulated rail brushes, motor, NEMA cabinet and components)
-
Outdoor Use (special paint, galvanizing, anti-corrosion materials, heated cabinet)
Motorized Gantry Bridge
Where the installation of a structure is difficult or impossible, the overhead crane on legs will be considered, generally for outdoor use.
