Compact Structure Light Weight European - Style Single Girder
Overhead Cranes Reduces The Construction Cost
Introduction:
European-style bridge cranes are compared with ordinary bridge
cranes. European-style bridge cranes have a reasonable and
lightweight structure and layout. The materials are made of steel
with higher strength, and the parts and components. Electrical
drives use a large number of more stable and reliable automatic and
semi-automatic industrial control circuits. It greatly reduces the
size of the overhead crane, increases the smoothness of operation,
greatly improves the maneuverability, and can control the position
and posture of the suspended objects more accurately. It is a good
lifting solution for high-end manufacturing industries. At present,
it is widely used by many high-end manufacturing enterprises.

Advantage:
1. The main structural characteristics of the crane
The main girder of the European crane adopts the box girder
structure. The advantages of this structure are that the structure
is reasonable and the strength is high. The crane hoist is firmly
combined with the lower wing of the main girder, and there is no
potential safety hazard. The European crane can increase the
effective lifting height, thereby improving the effective working
space, and the clear height of the space can reach 1.5 meters. In
addition, the wheel pressure of European cranes is less, so that
the rail-bearing beams will be reduced.
The traditional crane is limited by the design of the hoist, and
can only use the traditional I-beam structure below. This structure
is very unreasonable and the utilization rate is low. The most
important thing is the combination of the crane hoist and the lower
wing of the main girder. The form will cause the crane to break
away from the accident.
2. The space size of the crane
The space design of the European crane is more reasonable, the
appearance is light and beautiful, and the limited space of the
workshop can be used reasonably and effectively. The limit distance
between the hook of the European crane and the walls on both sides
is relatively small, and the headroom is low.
The appearance of traditional cranes is relatively thick and heavy,
which does not meet the current design requirements, and its limit
size in vertical and horizontal directions is relatively large.
Under the same factory structure, the space utilization rate of
traditional cranes is relatively low.

Application:
Single-girder bridge cranes have many uses and are widely used in
real life. In many factories, many product manufacturers choose
cranes for easy handling, and single-girder overhead cranes are
more prominent in terms of assisting and transportation.
In addition to general machinery workshops, single-girder overhead
cranes are widely used in petroleum and petrochemical, railway
construction, civil aviation airports, hydropower plants, ports,
papermaking, building materials, metallurgy and other workshops,
warehouses, and material yards.
