To correctly choose the size and selection of the crane, many factors must be considered to determine the correct crane type and corresponding capacity. Should it be a heavy crane? Boom truck crane? Rough terrain crane? Before choosing a crane, you must determine the weight, size, location, range, obstacles, and other factors of the load.
Here are some key steps:
1.Calculate the maximum radius from the center of the pin.
- Confirm the total weight of the load. If you don’t know, please consider consulting an engineering professional.
- Determine the gap problem, whether it is the height under the ceiling or the obstacles above the head.
- Consider the height of the obstacle between the crane and the load.
- Consider the height of the hook required for the lifting equipment.
- Leave the distance from the boom head to the hook.
- Determine whether obstacles will hinder the counterweight when swinging.
- Verify whether the crane needs to bypass obstacles during the setup process.
- Determine whether special rigging equipment is needed to avoid the removal of critical plant equipment during the lifting process.
- Consider what arm length is needed.
- Ensure that the ground can support the crane. May need further testing.
- Determine how the crane will enter the site. Can the road and entrance accommodate it?
- All these factors are essential for choosing a crane for safe and successful work.
