Elevator re-roping calculator
Rope It Right the First Time
Enter each car once — travel, ratio, sheaves — and get the counterweight block-up, length per rope and order length, and the reeving diagram from the same facts. Change one number and every result follows.
Simulation only. Every figure is an estimate to verify independently. Reports and job packets summarize what was entered, to send, print, or present to the building. They are not official records and are not for use in legal matters.
What Re-Roper works out
Enter the job once. Every figure reads from the same facts, and follows them.
FreeRope Length
Length per rope and the order length for the set, from the roping, the travel, and every sheave on the job.
Work out a length
ProCounterweight Block-Up
Counterweight to buffer, to the sixteenth, so the runby comes out right once the new ropes settle.
Open the block-up
ProRope Stretch Settlement
How far the new ropes will settle, from the rope's own stretch figures, the load, and the rope ends, with how far to trust it.
Open Rope Data
ProReeving Diagram
The rope path drawn from the job's own sheaves, from 1:1 to 4:1 and basement machines. Drag it to match the hoistway.
Open the diagram
Also in Re-Roper Pro: Rope, Hoistway, Equipment, and Governor Data, Sheave Grooves with the sheave inspection, the Figure Trace behind every figure, the Runby Log, Photos & Notes, Reports & Closeout with the PDF job packet, and your jobs synced between your phone and this site.
