Pre-Install Planning Guide

Lift Shaft Construction Detail

It is important to follow the guidelines laid out below to ensure a quick and cost-effective install and provide a good solid support system to have a long trouble free operating life of the Lift. The Shaft is made up of a few very important things:

  • A Pit at the Bottom to allow the floor of the Lift to drop into and have the floor of the Lift flush with the Building Floor when the Lift parks at the bottom location.

  • A Mast Wall that has extra Framing support to mount the Mast of the Lift to.

  • A 36” Hall Door at every Floor that the lift Parks at to allow passengers to enter and exit the Lift. The 36” width is important to allow people with wheel chairs and walkers good access as well.

  • An extra deep Single Gang Call Button Box just to the side of the Hall Doors on each floor, on the outside of the shaft wall. A separate 18 AWG-4 Conductor cable, for low voltage controls, must be run from each call button location back to the location of the Main Control Panel located in the Mechanical Room.

  • A Single Gang Junction Box laid on its side, above each Hall Door frame, opposite the hinge, facing into the Shaft. This is to allow the Door Lock to be mounted into the door Jam on install and then be terminated in this junction Box. A separate 18 AWG-4 Conductor cable, for low voltage controls, must be run from each Door Lock location back to the location of the Main Control Panel located in the Mechanical Room. The Cover for this Box will need to be very low profile, basically flush with the drywall surface.

  • Enough room above the last floor for the Lift drive to be housed.

Framing and Finished Dimensions

The shaft can be constructed of either 2x4 or 2x6 wood framing with 2 layers of 5/8” Fire Rated Drywall on the inside of the shaft. Insulating the shaft walls will ensure a nice quiet operation and will minimize noise transfer to the rest of the house. 

The wall that will support the Mast of the Lift must be totally plumb with multiple Studs Nailed together to give the mast a good solid foundation to secure to and give the installers some freedom to shift the lift side to side to get a perfect fit in the shaft. The Wall that the Hall Doors are in also needs to be totally plumb. It is very important that the walls of each floor line up exactly with the walls of the floors above and below it. 

In the Diagram please find the required measurements of the shaft foot print that are critical.

Dimensions: Interior Car Size and Required Interior Shaft Dimensions
Car: 54” x 48” 
Shaft: 57” x 58”

Car: 48” x 48”
Shaft: 51” x 58”

Note: Length (side of car against mast) x Width (side of car away from mast)
    Min length of our car is 48”
 

Pit Requirements

The Pit, below the Bottom Floor, must not be proud of the finished drywall surface. This is so that the mast can be mounted flush to the wall without the pit causing the installers to have to shim the mast the entire length of the shaft to get a truly plumb mast install.

 

The pit must also be 12” deep to house the floor of the Car, and allow a safe loop of the control cables below the car when parked there.

 

The floor of the pit must be level, especially on the mast wall, so that the mast structure can rest on the floor to help the Fasteners, holding the Mast to the wall, to support the weight of the Mast, Car and the Entire Load.

Control Panel Location & Wiring  Requirements

The Control Panel is a 24” x 24” box that is 12” deep that needs to be mounted in a mechanical room at a maximum height of 67 from the top of the panel to the floor. It needs to have 18” of clear space above it for a Brake Resistor, along with 39” clear space in front of it.

A conduit will need to be run from the bottom of the panel to the Lift Shaft for a multiconductor control cable to be run from the control box to the user interface inside the Lift Car. In the shaft, it will need to come out of the wall on the Same wall as the mast, about 4.5” from the corner opposite from the Hall Door Opening. It can come out anywhere in the lower half of the shaft’s total Height.
 

Main Power Requirements

The Haynes Lift System to be fed from 20 Amp. 4 Wire 240 VAC, with a Neutral wire (Black, Red, White & Gnd). This must terminate in the Mechanical Room just below the Control Panel so that it can enter it through a Strain relief from the bottom of the Panel.

Hall Door Interlocks

A Single Gang Junction Box is required to be laid on its side, above each Hall Door frame, opposite the hinge, facing into the Shaft. This is to allow the Door Lock to be mounted into the door Jam on install and then be terminated in this junction Box. A separate 18 AWG-4 Conductor cable, for low voltage controls, must be run from each Door Lock location back to the location of the Main Control Panel located in the Mechanical Room. The Cover for this Box will need to be very low profile, basically flush with the drywall surface.

Call Buttons

An extra deep Single Gang Call Button Box must be mounted just to the side of the Hall Doors on each floor, opposite the Door Hinge, on the outside of the shaft wall. A separate 18 AWG-4 Conductor cable, for low voltage controls, must be run from each call button location back to the location of the Main Control Panel located in the Mechanical Room.
