  4.    Hoist can be single speed or double speed lifting and traveling.

  5.    Electrics used Schneider brand original from France.

  6.    Motor,reducer,bearings use best brand in China

  7.    Control can be pendant control,wireless remote control and cabin control.

  8.    Safety devices included,such as buffer,limit switch,overload limiter,voltage and current protection equipment etc.

LD single girder crane not suitable for working under the following conditions

■ Environments with explosion and fire hazards

  Places with relative humidity greater than 85% and environments full of corrosive gases

  Lifting molten metal, toxic substances and flammable and explosive substances

For working under the above conditions, please consult us, we will carry out special design and manufacture in accordance with relevant standards and regulations.

The difference between single girder eot crane and double girder bridge crane

■ Differences in working environment

Generally speaking, single-girder bridge cranes are often used in places with short spans, low lifting capacity, and small working spaces. The double-girder bridge crane is used in places with large span, large lifting capacity and large working space. Comparing the two bridges cranes, the working level of the double girder bridge crane is higher.

■ Structural differences

Single-girder eot cranes are lighter in weight, relatively simple in structure, and relatively simple to install, dismantle, and maintain, while double-girder bridge cranes are heavier in weight, more complex in structure, and have higher requirements for assembly, disassembly, and maintenance.

■ The difference in manufacturing cost

Because the fuselage of the single-girder crane is relatively small, the consumables are small, and the manufacturing cost is not high. The double-girder crane has a relatively large fuselage, many consumables, and high technical content, so the construction cost is relatively high.

■ The difference in mechanical properties

The rated lifting capacity of single-girder overhead travelling cranes is small, the working level is relatively low, and the stability is not high, while the rated lifting capacity of double-girder cranes is relatively large, and the working level is higher and the stability is relatively better.
