In a highly competitive world there is no place for lack of reliability. This is applicable in all fields of economic and social activity. In particular, it acquires greater relevance in the operation of lifting equipment and cargo transportation.
The main function of crane work is the lifting of material loading and unloading. For this, every operator must consider some concepts and guidelines to perform their daily work respecting the standard safety measures.
Main causes that cause accidents
If we analyze this cause in particular, we can divide it into three aspects:
a) Poor staff rating
In general, the training of the lifting equipment operators is done through the transmission of knowledge of the oldest operators, and not for that reason more experts. This is the first risk that must be minimized by adding to the practical training, the necessary technical knowledge. In this way, it will be possible to evaluate, from the point of view of safety, the risk situations that are presented to the operator.
b) Incomplete training
The training provided to the operators only meets the requirements of the intrinsic operation of the equipment. The current trend shows that it is essential that the operator has knowledge of fault diagnosis, maintenance, and safety and hygiene, in order to develop preventive activities, which allows him to decide in critical situations.
c) Lack of particular knowledge about lifting operations
Involved actors other than the team itself. It is necessary, then, to have a greater universe of knowledge about other related activities that are developed in the context. For example, the inspection of slings and their use, operations close to power lines (currently fifteen people per electrocution per year by discharge through cranes), signals and, especially, the programming of critical loads. It must be taken into account that a failure or breakage of a sling, which produces as a result
final the overturning of a crane, is cataloged as human failure. This is because the operator must know the status of the lifting accessories.
In particular, its occurrence may be due to the following factors:
a) Lack of compliance with the preventive and predictive maintenance program
Although this is not a general issue, it has been possible to observe an important gap in maintenance policies. Currently only corrective maintenance is being carried out.
b) Absence of data and knowledge for maintenance
The lack of repair histories has been verified, and very especially the absence of manuals of the manufacturer that are the ones that provide the information for its correct maintenance.
c) Use of unqualified workshops
The repair of a lifting equipment must result in maintaining the safety conditions with which the equipment was designed. The use of unqualified repair shops puts this situation at risk.
d) Use of equipment of a lot of antiquity
The use of old equipment increases the risks of any operation. This is due, basically, to the possibility of the occurrence of mechanical failures.
Failure of the operation due to the environment
The experiences make operators have to have the training and instructions necessary to assess the risks when the environment is not conducive.
