MACHINE-ROOM-LESS (MRL) ELEVATOR DESIGNAdvantages:

Domestic origination (Hollister Whitney, Quincy IL)

Compliant with FTA “Buy America” requirements (49 CFR. Part 661)

100% Non-ProprietarySeamless interface with multiple PLC based (per APTA) control systems

Green Application relative to other arrangementsLower Motor/Brake BTU outputLower HP requirements than other elevator arrangements for the same speed and capacityRegenerative drive capability

Smaller building footprint required

Faster car speed than typical hydraulic elevators

MACHINE-ROOM-LESS (MRL) ELEVATOR DESIGN

Disadvantages:–Greater Initial Cost vs. Comparable Hydraulic setup

–Structural Loading Considerations– Pit Floor and Tower Structure

– Increased maintenance costs vs. traditional Hydro but comparable to traditional traction machines

–Longer installation timeline

– Increased pit and overhead requirements vs. Hydraulic

–Climate control required at top of hoist way for outdoor applications

MACHINE-ROOM-LESS (MRL) ELEVATOR FEATURES

• Mechanically efficient gearless machine• Dual braking eliminates need for rope gripper• Manual brake release for emergency lowering• Minimal control space requirements (remote or local)• Rail mounted version• Remote Resettable governors• Optional Regenerative drive configurations

PERMANENT MAGNET GEARLESS MACHINE
