Choosing the correct mobile crane requires more than comparing the load weight with the crane’s advertised tonnage. A 50-ton or 100-ton crane cannot lift its maximum capacity in every position.
The appropriate crane depends on the load weight, working radius, lifting height, boom configuration, site access and ground conditions.
After identifying these requirements, review Dar Al Khulood’s mobile crane rental in Muscat and across Oman for current availability and project support.
Confirm the Load Weight
Begin with the verified weight and dimensions of the item being lifted.
Provide:
- Confirmed load weight
- Length, width and height
- Manufacturer or fabrication drawings
- Centre-of-gravity information, where available
- Approved lifting points
- Required lifting accessories
Avoid estimating the weight when reliable documentation can be obtained.
Measure the Working Radius
Working radius is the horizontal distance between the crane and the load during the lift.
The crane provider should know:
- Pick-up radius
- Placement radius
- Crane setup position
- Obstacles between the crane and load
- Areas where the crane cannot be positioned
As the working radius increases, the crane’s available lifting capacity normally changes. This is why crane tonnage alone is not enough for selection.
Determine the Lifting Height
Provide the required placement height and details of anything the load must clear.
Consider:
- Building height
- Structural platforms
- Pipe racks
- Scaffolding
- Existing equipment
- Overhead services
- Load dimensions
The required boom length must be reviewed together with the working radius.
Check Site Access
Confirm that the crane can reach and safely set up in the proposed area.
Check:
- Gate and road width
- Turning space
- Overhead clearance
- Ground condition
- Space for outriggers
- Underground services
- Nearby excavations
- Traffic restrictions
Site photographs and a simple layout drawing can help the crane provider understand the requirement.
Review Ground Conditions
The crane setup area must be suitable for the intended equipment and configuration.
Inform the provider about:
- Soft or recently filled ground
- Slopes
- Underground chambers
- Culverts
- Basements
- Trenches
- Excavations
- Uneven surfaces
Ground preparation should be reviewed by the responsible project and lifting personnel before crane setup.
Provide the Project Schedule
Include:
- Required mobilisation date
- Lift date
- Rental duration
- Daily working hours
- Standby requirements
- Night or weekend work
- Demobilisation date
Large cranes, remote projects and shutdown work should be planned early.

Frequently Asked Questions
Does a 100-ton crane lift 100 tons at every radius?
No. The usable capacity depends on the crane model, radius, boom length, configuration and site conditions.
Can a crane be selected using only the load weight?
No. Radius, height, access, ground conditions and obstacles must also be considered.
Is an operator available with the crane?
Operator-supported crane rental may be available depending on the project, location and current equipment availability.
