Every Lift Starts With a Plan.
Before any crane leaves our yard, we've already engineered your lift. Site surveys, load calculations, rigging diagrams, and permit coordination — all handled by our experienced team.
Why an Engineered Lift Plan Matters
An engineered lift plan is the foundation of every safe, successful crane operation. It documents the crane configuration, load path, ground bearing pressures, rigging geometry, and personnel positioning required to execute the lift without incident.
At Big Lift Crane Service LLC, no lift goes forward without a documented plan reviewed by our team. Whether it's a routine rooftop HVAC pick or a complex multi-crane tandem lift, we treat every job with the same level of engineering rigor.
No lift leaves our yard without a documented plan.
From a single HVAC pick to a 500-ton tandem lift — every job gets the same engineering rigor. That's how we've maintained a zero-incident safety record for over 20 years.
Our Lift Planning Process
Site Survey
We visit your site to assess ground conditions, overhead obstructions, access routes, and any constraints that affect crane placement and boom configuration.
Load & Rigging Analysis
Our team calculates load weights, center of gravity, rigging angles, and sling capacities to determine the safest and most efficient lift configuration.
Crane Selection
We select the right crane from our fleet based on lift radius, required capacity, site access, and ground bearing requirements — never over- or under-craned.
Plan Documentation
A formal lift plan is produced including crane charts, rigging diagrams, load path drawings, and a pre-task safety checklist for the crew.
Permit Coordination
We assist with permit acquisition including road use permits, oversize load permits, and any municipal approvals required for your project.
Pre-Lift Briefing
Before the first pick, our operator and crew conduct a full pre-lift safety briefing with all personnel on site to review the plan and emergency procedures.
What's Included in Every Lift Plan
Crane Configuration Diagram
Boom length, jib configuration, counterweight setup, and outrigger spread documented to scale.
Load Path Drawing
Overhead view of the lift showing pick point, set point, swing arc, and exclusion zones.
Rigging Diagram
Sling type, length, angle, and rated capacity for every component in the rigging assembly.
Ground Bearing Analysis
Outrigger pad sizing and ground bearing pressure calculations to protect your site surface.
Crane Capacity Chart
Manufacturer load chart excerpt confirming the crane is within rated capacity at the required radius.
Pre-Task Safety Checklist
Crew sign-off sheet covering weather limits, exclusion zones, communication protocols, and emergency procedures.
