Overhead crane is Hengjia in workshops, warehouses and empty field for material lifting material lifting equipment. Because of its ends located in the tall concrete pillars or metal bracket, shaped like a bridge. Overhead crane overhead bridge along the laying of tracks on both sides longitudinally running, you can take advantage of the space under the bridge lifting material from ground equipment obstacles. It is the most widely used, the largest number of a lifting machinery.

Single girder overhead crane structure and Precautions Introduction
Single
girder overhead crane with double girder overhead gantry cranes, are a bridge
crane, also is a kind of lifting machinery, lifting machinery in it, a
single beam bridge crane is the most widely used, the number of Up to one, can be used in the steel industry, railways, ports and logistics industries.Simply
put a little single-girder overhead crane basic concepts, here, we have
to specifically talk about its structure and use precautions, hope that
through the introduction of this article, the reader can have some
knowledge of the Steel crane, the paper if inadequacies, the reader pointed out, Xiao Bian future corrections.1 single girder overhead crane structureSingle
girder overhead crane is generally located in the ends of concrete
pillars or metal bracket, similar shape with the bridge, the bridge is
laid on both sides along the elevated track running longitudinally,
while the space below can be used to bridge lifting material , ground equipment will not be hindered.2 single girder overhead crane Precautions(A)
each crane must be hung on the nominal weight is marked with signs,
lifting objects or equipment indicated on the label should not exceed
rated capacity.(2) Cranes at work, is prohibited in the bridge with a hook on someone or give as gifts.(3) the operator must concentrate in the operation, not allowed to talk to each other, smoking or doing work related things.(4) equipment, tools, etc. can not misplacing the car should be clean and tidy.(5) if the following conditions are not allowedhoist gantry crane lifting, as follows:a. rope tied strong or do not meet the requirements for safe use;b. mechanical overload operation;c. goods without proper safety protection measures;d. lift mechanism is faulty.(6)
If you are running there are no obstructions on the line, then the hook
and hanging objects or spreader underside must leave the ground two
meters above the job, if there is an obstacle, you must be at least 0.5
meters high over obstacles.(7)
If the nominal weight lifting is less than 50% of the objects, allowing
the two organizations to run, but when the object is heavier than
nominal weight of 50%, you can only run one.(8)
Always check the limit switches and interlock protection device; when
there is a problem down the brake, and definitely not lift heavy
objects; in the parking can not touch the limit switch by using a method
to achieve.(9) certain parts of the eot crane when welding, should set up a dedicated ground, can not use the body as a ground.(10)
for inspection or maintenance work should be after a power outage and
blackout job to hang a sign, if you need live action, we must do a good
job security, repair or inspection of the machine when used in lighting
voltage must be 36 volts or less.(11) Finally, to make periodic safety checks and pre-preparatory technical work.
