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.
