In many major cities skylines, the telescopic tower cranes are visible. These stationary balance cranes allow its operators to reach out to the great heights and offer some superior lifting capacity as it balances the cranes that are fixed to the ground on the concrete slabs or are attached to the sides of the structures. There are a few larger tower crane for sale that can reach up to 1000 feet in height with a lifting capacity of over 100 tons as discussed.
With great power comes great responsibility as the saying goes. Despite OSHA and the National Commission for the Certification of Crane Operators publishing a final rule schedule for the tower crane operator certification in November of 2018, there have been several notable instances recently.
The largest and few of the most expensive pieces of equipment on a construction site is the tower cranes. While installing, operating, and disassembling a tower crane, it is in the interest of all to take possible precautions. We have placed together a tower crane safety checklist that includes the common hazards to consider some best practices to help keep your crane operators and the other employees safe.
Falling loads, overloading and electrocution are a few of the most common tower crane-related accidents. On how to avoid the accidents that stem through them, here are few of the causes of these hazards posed:
· Falling Loads
Mechanical failure, improperly secured loads, two blocking, and operator incompetency are the causes of the falling loads that are included but it snapped the lines that are caused by higher wind speed.
You need to make sure that all the crane operators, lifting supervisors, riggers, etc can help avoid these types of accidents as they are decently certified and the certifications are all updated. The loading procedures should be followed. Before each of the shift and throughout the day, the weather conditions should be monitored well.
There is always a higher risk that the crane could be suffering from stress fractures or worse, completely collapse causing relative damage to the crane and this surrounds the equipment and structures, leading to injuries and even death when the load of the crane exceeds the lifting capacities. You need to make sure that no load is over the lifting capacity of the crane and that all the loads are secured in a proper way with the loading procedures.
· Electrical Issues
It all involves the crane touching the power lines or other high-voltage power sources as approximately half of all the tower-crane related accidents are involved here. The workers are at a higher risk of electrocution as they are in direct contact with the crane at the time of contact. You also have to ensure that there is sufficient clearance for the jib to move as you should monitor the weather throughout the day.
From the assembly of the crane to its installation, operation, and dismantling, below is a few of the most common safety checklist considerations to be made. For the product-specific daily, weekly, and monthly safety and operations checklists, you need to consult your crane manufacturer.
· There should be a professional Engineer or an Approved Crane Contractor who should be performing all tower crane design installation.
· Only a certified competent professional should be installing the lighting and electrical wiring.
· A tower crane can only be operated by a certified competent person and they should never be operated without a supervisor on site.
· Perform all the safety checks as recommended by the manufacturer at the start of each working day. Limit switches, electrical cables, brakes, as well as visual inspection for anything out of ordinary should be included in these.
· Under the loads and the operators, employees should never stand.
