Never walk under a loaded crane during a lift. There should never be any sudden acceleration or deceleration of the load during the lift. Move crane controls slowly and avoid any abrupt or jerky movements of the load. Before lifting, be sure that all loose materials and parts have been removed from the load.In the US, the safety factor must be between 2:1 and 3:1 for hoisting devices. Employers must ensure that the load capacity of the gantry crane is not exceeded and that the crane is used only for its intended purpose.Loads should not be suspended over personnel below. Never allow anyone to ride on the hook or load at any time. Never leave the controls unattended while a load is suspended. Become familiar with the location of the crane/hoist disconnect switch.
How do you maintain a gantry crane : Regular maintenance includes tasks such as lubricating moving parts, inspecting and replacing worn-out components, and checking for any signs of damage or deterioration. By following a comprehensive maintenance plan, operators can extend the lifespan of the gantry crane and optimize its performance.
What should you always avoid when working around cranes
Do not stand or position yourself where the crane could cause you to be struck by or pinched between any moving areas. Warning signs and barricades should be placed so that workers can clearly see the swing radius of the crane and where to avoid.
How often should gantry cranes be inspected : once a year
OSHA requires that all active cranes must be inspected once a year at the minimum. However, depending on the cranes usage, additional inspections will be required. Crane inspections fall under two general categories based on the intervals between inspections.
Risks of using a crane include:
crane structural failure, overturning or collapse.
the crane or its load contacting or colliding with people or other plant and structures.
falling objects.
Electrical Hazards
High-voltage power lines can cause injuries such as burns, shocks, or fatalities. The crane boom or hoist line is at risk of hitting a power line when working in close proximity. This creates an electrical current that can injure the operator at the controls.
How do you inspect a gantry crane
1 Ensure load rating is marked on each side of the crane or hoist and legible from the floor. 2 Check that warning labels are clean and legible. 3 Check hooks for deformation, cracks, bends, and excessive thread damage.The path of each load must be planned to prevent swinging loads from passing over workers. It is the responsibility of the subcontractor to utilize the necessary precautions (barricades, horns, spotters) to keep workers out of the swing path.Reasons behind crane accidents include:
The crane buckling or collapsing. Most cranes have support structures (such as stabilizers and outriggers) that prevent them from moving as they operate.
Improper assembly.
Improper/Insufficient employee training.
Mechanical failure.
Electrocution.
Frequent Inspection
The crane inspector must check: All functional operating mechanisms to make sure there's no maladjustment that could interfere with proper operation or excessive wear of any components. All parts of air and hydraulic systems, like lines, tanks, valves, and drain pumps, for deterioration or leakage.
What is the safety inspection checklist for a crane : CRANE INSPECTION
1 Hook and Hook Latch.
2 Over-Hoist Limit Switch. 3 Boom-Limit Switch.
4 Boom Angle indicator. 5 Condition of boom. 6 Condition of Ropes.
7 Size and condition of the sling.
8 Swing Brake & Lock.
9 Propel Brake & Lock.
10 Hoist Brake & Lock.
11 Boom Brake & Lock. 12 Oil Leakages.
How do you check a crane safety : Operator cab inspection:
Determine the crane's visibility from the operator cab.
Check if the emergency stop switch is working.
Check if the radius indicator is visible.
Check the control systems and brakes.
Conduct a no-load test pre-operation.
Ensure the two-way radios are working.
What is the 3 3 3 rule for lifting
Implement Safe Lifting "3, 3, 3" as a hold point of lifting procedures before lifting, which can effectively improve the safety of lifting operation: • Keep 3m away from materials being lifted; • Lift up the materials 300mm from ground; and • Wait for 3 seconds for stabilising the lifting object before lifting … Crane accident fatalities occur from a variety of causes. The most common cause of fatalities is workers or bystanders who are struck by an object that falls from the cranes. Other causes include being run over by a crane, falling from a crane, and electrocution.The most common cause of crane accidents is cranes having contact with power lines or other power sources, making up around 45% of all crane-related accidents.
