Setting & Plumbing the Hoistway

1

Open the Door

The elevator is shipped with the car in between stops 1 and 2. When the hoistway is partially lowered into the pit, open the door and enter the pit. A pin with a streamer attached to the end is holding the door partially open. Reach your arm through the opening, feel your way up the streamer to the pin, and pull it away from the door to release.

Anchor Bolts

Anchor bolts should have a ¾” nut and washer on them.
3

Lower the Tower

Lower the tower over the anchor bolts until they are resting on the leveling nuts.
4

Leveling Nuts

Using the appropriate wrench, tighten/loosen leveling nuts in each corner until the plumb bob is not touching the edge of the loop. A laser level should be run up the rail to fine-tune adjustments and get it perfect. The crane can lift the tower slightly. Once the hoistway is level and plumb, place a washer and nut on top and tighten the nut. A laser level should again be run up the rail to make fine-tune adjustments and get it perfect.

Install Washers and Nuts

When the hoistway is plumb, install provided washers and nuts on top of the base plates and tighten. Then, pack non-shrink grout below the base plates to support them.
6

Bolt Any Additional Towers

If there are additional towers, they simply bolt together. No additional plumbing is needed on upper towers since the rails and towers are built and aligned in the factory. Also, our elevators have temporary work platforms at the top of each tower, with nuts and bolts strapped to the rails nearby. From that platform, guide the upper tower onto the alignment pins and ensure the rails seat to each other. Then, bolt the tower corners together and the upper rails to the fishplates.
7

Jacks and Buffer Stands

The jacks and buffer stands should be set the same distance off the pit floor as the hoistway base plates. Use the included steel shims (strapped to a beam in the pit area) to support them, use concrete anchors to bolt them in place permanently, and grout below.
