Planning Lift Software Made Simple
Spreader Bar Basic Calculator
Spreader Bar Basic is a calculator that calculates forces on spreader bar pipe, slings, and shackles for a wide range of lifting configuration. Loads are calculated and assessed based on ASME BTH-1 calculations. Three options of shackle types are available to choose from, as well as three options of sling types, 1-Part Mechanical Spliced IWRC (EIPS, 6X19), STRAND Mech. Splice Grommet IWRC (EIPS, 6X19), and Polyester Endless Round slings. Top sling configurations include vertical and basket. Unit selection (US Customary, British Imperial, & Metric). AISC Pipe and HSS round shapes, in US Customary, British Imperial, and Metric units. Integrated worksheet calculation tab providing details of spreader bar calculations Spreader Bar Chart Calculator. Report generation for graphical reporting of results. Spreader Bar Deflection Calculation, Sling capacity reduction calculation based on D/d and effective bearing area of the shackle.
Spreader Bar Plus Calculator
Spreader Bar Plus calculates loads on spreader bars when lifting with offset CGs. The loadings are calculated for pipe, slings, and shackles, while calculating and reporting ASME BTH-1 results. Three shackle type are available to choose from, as well as three options of sling types, 1-Part Mechanical Spliced IWRC (EIPS, 6X19), STRAND Mech. Splice Grommet IWRC (EIPS, 6X19), and Polyester Endless Round slings. With configurations of vertical and vertical basket. Additionally the program calculates the required difference in sling length needed to balance load and level lifts.

Crawler Crane Mat Calculator
SMART Rigger Crane Mat Calculator provides a practical means of calculating the effective bearing length of a crane mat. Offering different configurations, with customizable sizes of Mats. Size matting based on track pressures and allowable ground pressures, Using three different methods to assess the Timber Mat's effective length. Mat Strenght Method, Soil Capacity Method, Effective Length Method, which includes defection limitations. See shear, bending moment, shear stress, and bending stress profiles based on the matting loading profile.
Spreader Bar Basic for I-phone
Spreader Bar App calculates loading on the spreader bar pipe, slings, and shackles for a wide range of lifting configurations while calculating and reporting ASME BTH-1 calculations. Three options of Crosby shackle types are available to choose from in this version of the app, as well as three options of slings, 1-Part Mechanical Spliced IWRC (EIPS, 6X19), STRAND Mech. Splice Grommet IWRC (EIPS, 6X19), and Polyester Endless Round slings, for a vertical and vertical basket configuration. Provides spreader bar capacity charting, and report generation ready to email results.
Here's what people are saying about SMART Rigger Software
"... I have been using various versions of a “rigging calculator” for over a decade, and the SMART Rigger Software Spreader Bar Calculator is without a doubt the most complete version I have used. This program definitely covers all areas of concern when evaluating and designing a BTH rigging arrangement. The areas of input are easily navigated after a brief period of self-training, and an extremely thorough summary page neatly organizes the outputs for distribution to clients, and/or internal recordkeeping purposes. In my opinion, this program is a “must-have” for any rigging department..." Stephen Hitchcock General Manager – Heavy Lift Rental Division
