Sling angle factors θ is from horizontal; φ is from vertical. Tension factor multiplies the vertical share of one leg . sin θ is the geometric angle factor for equal-leg capacity comparisons, before product/hitch reductions. The last column is per-leg tension divided by total load for a centered two-leg pick.
Calculated trigonometric factors · equal-angle static geometry θ horizontal φ vertical Included β Tension factor 1/sin θ sin θ Two-leg T/W
Do not use angles below 30° without manufacturer or qualified-person guidance. Four sling legs do not establish equal sharing. Angle reference: Ashley Sling .

Support typeTwo crawler tracks Four outriggers UnitsUS · lb / ft / psf Metric · kN / m / kPa Allowable ground pressure · psf Reaction load multiplier
Reaction and allowable-pressure references / lift case Enter the governing reaction for each support from the manufacturer or engineered lift analysis, including the actual crane, counterweight, boom, load, rigging and lift orientation. Reactions are entered independently of Crane setup and must be updated when the lift changes. No equal-load distribution is assumed. Use 1 for the multiplier when the supplied reaction already includes required load factors.
Export ground bearing report Calculation method and support requirements Effective area = bearing footprint × effective contact percentage. Design load = entered support reaction × reaction load multiplier + pad/mat self-weight. Average design pressure = design load ÷ effective area. Design peak pressure = average design pressure × entered peak/average factor. Required effective area = design load × peak factor ÷ allowable pressure. Required footprint = required effective area ÷ effective contact fraction.
Use actual ground-contact dimensions for tracks or verified load-spreading mat dimensions. Full mat area cannot be assumed without verifying mat stiffness, strength and contact. A peak factor of 1 is uniform average pressure only; this tool does not predict crawler pressure distribution, settlement, soil bearing capacity, mat bending, punching, slope stability or underground hazards. Use site-specific allowable bearing pressure with its geotechnical safety factors already applied. A pressure comparison does not approve a lift.
