Machine Room Less Elevators: Frame Building Supported

MRL – Frame Building Supported

MRL Car Type Summary

The group one “Machine Room Less” is an engineered package design that utilizes an efficient gearless permanent magnet machine. This machine, with all the related traction components, is installed inside the hoistway eliminating the need for a machine room.

Engineering support and service
Shop drawings and group one installation drawings
Consolidated shipment when complete package is ordered

Advantages for the building owner:

Saving on valuable floor space
No contamination to the ground like on hydraulic applications.
Greater power efficiency
Superior performance and ride quality
Reduction on the elevator power feeder

Equipment Included:

Gearless MRL PM Torin machine
Governor and tail sheave
Overhead beams, machine bedplate, hitch plates, governor plate
Counterweight frame and weights
Car & cwt roller guides with mounting plates
Sling including: Crosshead, stiles, bolsters, brace rods, strike plates

Buffer stands, spring or oil buffers
Safeties
Underslung assembly with deflector sheaves
Guide rails, rail brackets with spreader plates, clips and fasteners
Car & cwt ropes and wedge sockets
Limit switches, mounting brackets & cam
All hardware included in labeled bags

Equipment Capabilities:

Passenger & service cars
Capacities from 2,100 lbs up to 3,500 lbs
Speeds from 100 FPM up to 350 FPM
Travels up to 200 ft

For building supported design machine beam pockets are required in the hoistway walls.

Hoistway dimensions are minimum clear inside requirements. Shorter installation times can be obtained by increasing these dimensions by up to 2”. For seismic zone 2 and up, add 2” to hoistway width to comply with Code requirements.

Use of 8mm and 10mm ropes for traction elevator was approved by A17.6-2010 effective 1st July 2010.

New York City Building Department has issued new rules governing the overhead requirements for MRL’s. Please contact a DEM Elevating Equipment representative.

Dimensions shown here are for reference only, consult your sales representative for final dimensions for your particular project.

Hoistway depth dimensions based on 8# cwt rails, if using 15# cwt rails, add 4″ to hoistway depth.

Building Supported MRL design with Torin TSM series machine.

*Spring buffers for car and counterweight / **Oil buffers for car and counterweight.

Based on ASME A17.1

O.H. Left column has spring or oil buffers with 6″ Runby / Right Column has all oil buffers with 0″ Runby.

Note: For cars with tall cabs add 1” to O.H. for every inch of cab height added.
