How to Choose a Self-Erecting Tower CraneThe right crane should be selected according to the project’s heaviest load, required working radius and hook height. Maximum lifting capacity should not be considered on its own because the crane’s capacity decreases as the load moves farther from the tower.
Important specifications include:
- Maximum lifting capacity
- Maximum load at the jib tip
- Available jib lengths
- Maximum working radius
- Maximum hook height
- Jib angle and raised-jib options
- Slewing radius
- Base and outrigger dimensions
- Transport dimensions and total weight
- Power supply requirements
- Erection and dismantling procedure
- Axle and towing options
The manufacturer’s load chart should be checked to confirm that the crane can handle the required loads at their planned working radii. Ground conditions, foundation or support requirements, site access, wind limits and nearby obstacles must also be evaluated.
