Urban Construction

Crane Selection Validation

The Mobile Hydraulic Crane is appropriate for the specified lift of 25 tons at 85 feet height. This crane type offers sufficient load capacity with a safety factor of 15% when properly configured with outriggers fully extended.

Optimal Crane Positioning

Based on the urban construction site constraints, position the crane at the north-west corner of the site with:

Minimum 20 ft clearance from overhead power lines
Outriggers fully extended on reinforced ground pads
Counterweight rotation zone clear of all obstacles
Access route maintained for emergency vehicles

Boom Length Calculations

Required configuration:

Main Boom Length: 110 feet
Boom Angle: 65 degrees
Working Radius: 42 feet
Counterweight: Full (22,000 lbs)

Safety Considerations

Load Capacity Margins

Maintain minimum 15% safety margin from rated capacity

Ground Bearing Pressure

Use 1.2m × 1.2m outrigger pads to achieve maximum 85 kPa ground pressure

Weather Limitations

Cease operations if wind speeds exceed 20 mph or during electrical storms

Step-by-Step Lift Procedures

Conduct pre-lift meeting with all personnel
Position and set up crane according to positioning plan
Verify all outriggers are fully extended and on proper support pads
Assemble and inspect all rigging equipment
Attach rigging to load with certified riggers
Clear all personnel from lift zone
Perform test lift of 1 foot and verify stability
Execute main lift with continuous communication
Position load at destination and secure before releasing rigging
Conduct post-lift inspection of all equipment

Risk Assessment

Hazard	Mitigation
Overhead Power Lines	Maintain 20ft minimum clearance
Ground Failure	Use engineered outrigger pads
Load Swing	Use tag lines and trained spotters
Personnel Injury	Establish exclusion zones

Pre-Lift Checklist

Crane inspection documentation verified

Outrigger pads properly positioned

Load weight verified against chart
