Every re-roping job, figured once.
Re-Roper is a calculator suite for elevator re-roping. Enter an elevator's facts once and every result reads from them.
Rope Data
Pick the rope, get the numbers.
Choose a manufacturer and a rope and the construction, grade, diameter, breaking force, and weight fill in, with the drive sheave D/d check and the stretch estimate beside them.
Rope length from the reeving, not a guess.
The roping ratio, travel, runby, and every sheave on the job set the length per rope and for the set. Drag the reeving diagram to match the hoistway.
Position
Block-up and sill offset, to the sixteenth.
Counterweight block-up and the car's sill offset at the top landing, from runby, stretch, and take-up, with the pit and overhead clearance checks against A17.1.
Your jobs, on every device.
Sign in and the jobs on your phone are the jobs on this page. Every elevator keeps its own record, and every calculator reads from it.
How it works
Create a job
A job is a building or work order. It holds one or more elevators, and each elevator keeps its own record.
Enter the facts once
Rope Data, Hoistway Data, Equipment, and Governor are the only places a fact is entered. Every calculator reads from them.
Read every calculator
Position, Rope Length, the Reeving Diagram, and the Code Reference update as the facts change, with pass and fail against A17.1 wherever the code applies.
Every page of the job
Four data pages hold the facts. Three calculators and the code reference read from them. Nothing is entered twice.
Rope Data
Manufacturer, rope, and size fill the spec in one tap, with the stretch estimate and the D/d check beside it.
Hoistway Data
Travel, runby, pit depth, overhead, and rated speed, with the clearance checks read as gauges.
Rope Length and Reeving Diagram
Length per rope and for the set, from a reeving diagram you drag to match the hoistway.
Equipment
Machine, controller, drive, and buffers, narrowed to what the job's speed and load allow.
Governor
Governor model, rope, trip speeds, and tension sheave, filtered to the models that fit.
Position
Counterweight block-up and car sill offset, with the live figure called out on the cutaway.
Code Reference
The A17.1 rules a rope job runs into, one card each, with this job's own figure beside the rule.
