Pick a vehicle, build an unassisted lift crew, and compare each person’s squat and deadlift capacity against the estimated load at the lift point.
Choose a lift crew. Each person contributes a conservative shared-lift capacity based on squat and deadlift strength.
Set the crew size and choose each lifter. The estimate includes a coordination reduction and a 15% safety buffer—no jacks, straps, or tools.
Safe capacity uses the lower of each person’s squat- and deadlift-based estimate. The team must clear the estimated load plus a 15% safety buffer.
Pick a crew size, then tune the people doing the lifting.
Different cars need different crews. Pick one and see whether the lift line can get it airborne.
