Overhead cranes are one of those powerful machines that assist us to lift massive weight and move heavy objects easier. They are one of the main supporters of the manufacturing and the construction industry. The overhead cranes basically ease the job. But it is very important to have proper know-how about it before actually operating and using it.
There are also chances of an accident waiting to happen if the operators don’t know how to use it safely and properly. Following these guidelines can help avert costly accidents and injuries. Keep in mind the load capacity. Any load that is greater than the rated load capacity of the crane may create mishaps. The brakes that are of prime importance so they need to be tested before using. If the brakes fail to hold the speed, slowly lower the load. This shall solve the problem temporarily. But it is wise to report the situation immediately and do not operate the crane until repairs have been made.
The parts should be inspected daily. Do not operate it if workings are worn or in disrepair. Examine pneumatic and hydraulic parts for leaks. Move the crane in all directions to check for smooth movement. Listen if there are any unfamiliar sounds and replace worn parts immediately.
Remove any loose materials or parts prior to lifting a load. The sling and hoisting ropes should be free of slack and the lifting device should be sitting in the hook’s saddle.Become familiar with the location of each of the crane’s controls, especially how to stop it in an emergency. Often that can be done by activating a disconnect switch, which should be within reach and in working order. Controls should be clearly marked as to their function.
Prepare for an emergency. Operators and site workers should know what to do in case of electrical, mechanical or power failures. Procedures should be implemented for retrieving an operator from a cabin an emergency situation. All cabs must carry fire extinguishers.
Identify the location and voltage of overhead power lines and de-energize the lines and erect insulated barriers before work starts. Exercise caution when moving on the uneven ground since the crane may bob or weave into the power line. Establish a safe travel route under power lines and operate at a slower speed. If an operator has trouble seeing power lines or clearance while moving the crane, a signal person should be on guard.
Switch all controls to the “Off” position prior to exiting the crane. Also, remove the load hanging on the crane’s hooks as if it falls then it may hurt anyone. So it is an intelligent thought to have proper maintenance guidelines for Overhead Cranes.
Safety terms and guidelines while using the overhead cranes.
If you happen to follow the right safety measures then you will be able to avert the costly injuries and life-threatening disabilities. Before you actually start this sort of bridge crane, you must ensure to read the operating manual thoroughly every crane has its own specific function. Further, you can also jot down a couple of functions which is common to all overhead cranes.
-Make sure to wear protective gear and head protective gear once you start with your job with or near any overhead cranes
– Before lifting or moving any cranes, you must make a point to check the clarity of visibility line all around and also lift the load high to clear all the obstruction below.
-You must clearly provide instruction to other about keeping the area clean and not moving or riding any load or the hook on the path.
– It is safe to move the load smoothly with much jerks or frequent move in any direction. Try to lift the weight in the vertical direction gently, meanwhile positioning the hoist directly above the load before lifting it and slightly lower it down below the hoist again.
-If you manage to keep the two long wraps of ropes on the hoist then will enhance the smoother movement.
-Monitor the signals only from the personnel operating the lift; however, you can only in the case of an emergency signal coming in.
-Don’t dare to exceed the lifting capacity of your machine. If it new then test it by lifting the weight up to few inches above the ground.
Maintenance of overhead cranes
For any device, maintenance is quite important but ironically people get a little complacent towards it from time to time. Nevertheless, it can lead to some fatal results besides leading to heavy toil on time, money and health. It is necessary to inspect your machine thoroughly from time to time. From your end what you can do is, you can check your machine for loose ends or hanging components. If you get some abnormal sounds or movements from hoist then immediately consult your technician.
