Description of Overhead Travelling Crane
Overhead cranes come in all different sizes, shapes, and capacities
and selecting the right type of overhead crane is essential to
streamlining your production processes. There is no “one size fits
all” approach to identifying the right type of crane for your
business’ lifting needs, so the following need to be taken into
consideration when choosing a crane for your facility:
Motion of the crane structure
Weight and type of material / load
Location of the crane—indoors or outdoors
Required capacity
How often the crane will be used
Length or span of the crane

Part of the structural performance design of Overhead Traveling
Cranes
Bridge – A load-bearing beam that runs the width of the building.
This is the primary structural component that connects the runways
and moves the hoist forward and backward using a trolley.
A bridge can be comprised of one or two beams—more often referred
to as a single girder or double girder design. Girders can be made
of rolled steel or can be fabricated by welding the beams into a
steel box design.
Runway – What the bridge crane travels on to move the crane up and
down the bays. These are typically part of the building structure,
as beams, and there are two (2) per overhead bridge crane system.
Runway rail or tracks – Rail supported by the runway on which the
crane travels. Top-running cranes typically run on ASCE/railroad
rails. Gantry cranes can also utilize a rail or track system
installed in the floor to move the bridge back and forth.
Installation And Maintenance of Overhead Traveling Cranes
Eot crane installation
The eot crane installation should be carried out in strict
accordance with the rules and order of the specification. Besides,
we have a professional technical team with several engineers to
provide the equipment installation guide service and training. For
different types of cranes, they have different installation
methods, so before installation, workers should understand the
structure, parameters, and installation site of the crane. During
the installation, they should be careful and wear helmet and belt
seat for safety. The installation work should be done under
professional guidance.
Eot crane maintenance
Eot crane maintenance is indispensable in daily work for that the
crane failure may directly affect the safety of workers and the
equipment. A routine maintenance for hook, wire rope, reducer,
brakes and other components should be done, especially the hood is
the most frequently used device in the crane operation, and it
bears all the loads. Once the hook gets damaged or broken, it may
cause a serious accident. Therefore, the maintenance staff must be
careful during inspection and solve the problems in time.
