Precautions for the installation and use of bridge cranes

Overhead cranes are used in the manufacturing and construction industries for the lifting and transportation of various materials. If installed and used properly, these systems can promote safer and more efficient operations. However, improper installation and use may cause accidents, which may cause serious injury to life and limbs. The key to preventing these incidents is to identify their source and allow industry professionals to better understand how to avoid them.so,Precautions for the installation and use of bridge cranes


The following blog post summarizes the four major hazards associated with crane installation and use, as well as recommended safety procedures to avoid these hazards.
Cranes are common hazards.
Overhead crane accidents mostly come from one of the following four main reasons:

  1. The load is too large.
    OSHA estimates that 80% of crane accidents and failures are caused by exceeding the rated capacity of the crane. Overloading can cause major damage to the crane, reduce its structural integrity, and often lead to complete failure. Once these situations occur, crane operators and nearby people may be injured due to parts falling or malfunctioning.
    Overloading can happen in several different ways:
    Handling loads heavier than the crane capacity.
    swing. Drag or drop the load suddenly.
    Side-mounted boom (the center of gravity of the load is not directly below the crane at any time)
    For crane operators, understanding the main causes of these overloads and how to avoid them requires comprehensive training. A typical training program may include teaching the principles of load handling and lifting capacity under various conditions and operating conditions.
  2. The material falls off.
    Falling materials may cause serious injury or death in the workplace or construction site. There are many reasons for these incidents, such as:
    Visual impairment
    Improper or insufficient material assembly.
    Mechanical failure
    Materials are moved out of time.
    The operator is incompetent.
    Most (if not all) of the causes of material falling can be avoided by careful operation of the crane, which can be facilitated by hiring a well-trained and qualified crane operator.
  3. Insufficient inspection and maintenance.
    Through the use in operation, the load-bearing equipment may damage the performance. This damage may manifest as abrasion of ropes, wires, and structural components. Since these systems play a key role in lifting and transporting heavy materials, regular inspections to ensure that they are in normal working condition are essential to prevent employee injuries and deaths.
    According to the overview of the Crane Manufacturers Association of America (CMAA), crane inspectors should have the following qualifications:
    Check, repair and test cranes and lifting equipment for at least 2000 hours.
    Familiar with safety and design standards; federal, state, and local regulations; and safe operation codes.
    Know the correct report and documentation protocol.
    There are four types of inspections, some are carried out by crane inspectors, and some are carried out by operators:
    First inspection: OSHA1910.179 requires the first inspection of all newly modified cranes.
    Pre-shift inspection: It is recommended to check each time the crane operator changes, such as when a new shift starts.
    Frequent inspections: These are completed by certified inspectors. The frequency of these inspections varies with crane type, size and capacity.
    Regular inspections: These are detailed visual inspections and operational inspections covering all parts of the crane.
