LD model single girder overhead crane is characterized by more reasonable structure and higher strength steel as a whole crane.
Single girder overhead crane is more typical when lifting capacity less than 20T.
Used together with CD1 model MD1 model electric hoist as a complete set, it is a light duty crane with a capacity 0.5 ton ~ 32ton.
The span is 7.5m~ 22.5m. Working duty is A3~A5, working temperature is -25-40ºC.
This product is widely used in steel mills, warehouse, hydropower station, production workshop, production line, materials stocks,
Equipment assembly etc to lift goods.
We have comprehensive standard equipment and professional design engineers to offer best solutions for individual requirements.
This product has two operational methods, ground(pendent controller /remote controller) or operational cabin room.

Advantages of a single girder design:
1)Less expensive due to a simpler trolley design, reduced freight costs, simplified and faster installation, and less material for the
Bridge and runway beams.
2)Most economical option for light to medium-duty cranes
3)Lower loads on the building structure or foundations due to a reduced deadweight. In many cases, it can be supported by existing
Roof structure without the use of additional support columns.
4)Better hook approach for both trolley travel and bridge travel
5)Easier to install, service, and maintain
6)Ideal for workshops, warehouses, material yards, and manufacturing and production facilities
7)Lighter load on runway rails or beams means less wear on the beams and end truck wheels over time
8)Great for facilities with low headroom

Shipping way of MINGDAO Cranes:
♦ Electric parts are packed by high quality plywood crate, to reduce distortion in conveying.
♦ Main beams, end beams and trolly/winch are packed by plastic woven cloth. It can reduce
Abrasion during the transportation.
♦ If the size are suitable for container ship, usually by container.
♦ Big size, usually by bulk ship or by container after truncation.
♦ Transport ways are based on reducing cost & keep safety.
