Elevators and Escalators? The Vertical Transportation Field Guide is the two books in one for CAD $15.99 a month. Buying the two separately is CAD $25.98, so it saves you CAD $9.99 a month (CAD $79.99 a year on the yearly plans).

The guides are written to the 2016 code book (ASME A17.1-2016 / CSA B44-16) and flag the major changes in the 2022 edition. Tell the guide where you work and it knows which edition is law there: where that is 2022, it leads with the newer rule. See which edition applies where you work.

Escalator Field Guide
what is the heaviest that the deck lid can be
Access plates at the top and bottom landings must not take more than 310 N (70 lbf) of effort to lift open.CSA B44 Part 6 · 6.1.7.3.1

A real answer from the guide. Ask it the way you would say it: deck lid, deck plate and pit cover plate all find the access plate.

Escalator Field Guide
how much force will trip a comb impact
It has to cut power by 1 780 N (400 lbf) pushed horizontally at either side of the combplate, or 3 560 N (800 lbf) at the centre of the front edge, or 670 N (150 lbf) upward at the centre. Units installed under A17.1b‑1992 and later.CSA B44 Part 6 · 6.1.6.3.13

A real answer from the guide. Ask it the way you would say it: comb impact, comb plate impact and comb-plate impact all find the comb-step impact device.

Elevator Field Guide
what is the maximum force a door can close with
The force needed to stop a closing door must not exceed 135 N (30 lbf), measured on the leading edge with the door between one-third and two-thirds of its travel.CSA B44 Part 2 · 2.13.4.2.3

A real answer from the guide. Ask it the way you would say it: hall door, landing door and outer door all find the hoistway door.

Elevator Field Guide
how far can the car door open between floors
Outside the unlocking zone the car doors must be arranged so they cannot be opened more than 100 mm (4 in.) from inside the car.CSA B44 Part 2 · 2.14.5.7.1

A real answer from the guide. Ask it the way you would say it: cab finds car, and gate lock or hall door lock finds the interlock.
