Things to Check in a Crane Before Heavy Erection
Before performing heavy erection with a crane, it is crucial to conduct a thorough inspection to ensure the safety and efficiency of the operation. Here are the key areas to check:
General Visual Inspection
Start by conducting a walk-around inspection of the crane. Pay close attention to the following components:
- Hydraulic system
- Controls
- Lifting mechanisms
- Outriggers
- Boom
- Tires
- Brakes
Inspecting these components will help identify any visible signs of damage or wear that could affect the crane’s performance during heavy erection.
Document Inspection Records
According to OSHA 1910.179, it is essential to maintain inspection records for cranes, especially for new and altered cranes. Before heavy erection, ensure that the crane has undergone an initial visual inspection and that the inspection records are up to date.
Calculate Anticipated Loads
Before lifting heavy loads, it is crucial to calculate the anticipated loads accurately. Consider the weight of the load, working radius, and boom dimensions to ensure that the load falls within the crane’s rated capacity. This calculation helps prevent overloading, which can lead to accidents and damage to the crane.
Check the Area Around the Crane
Before heavy erection, it is vital to assess the area around the crane to ensure a safe working environment. Measure the distance from the crane’s path to power lines, structures, other equipment, and other workers. Maintaining a safe distance will prevent any potential collisions or accidents during the operation.
Counterweight
Counterweights play a crucial role in maintaining the stability of the crane during heavy erection. Before starting the operation, ensure that the counterweights are properly installed and secured. This will help prevent the crane from toppling over and causing accidents or damage.
Wire Rope, Chains, and Hook
Inspect the wire rope, chains, and hook for any signs of damage or wear. These components are essential for lifting heavy loads safely. Any visible signs of damage, such as fraying or corrosion, should be addressed before proceeding with the heavy erection.
Safe Load Indicator (SLI)
Prior to starting the operation, examine the Safe Load Indicator (SLI) of the crane. The SLI provides crucial information about the crane’s load capacity and helps prevent overloading. Ensure that the SLI is functioning correctly and that the load limits are clearly visible.
By following these essential checks, you can ensure the safety and efficiency of heavy erection with a crane. Remember to prioritize safety and always consult the manufacturer’s guidelines and industry best practices.
