Build – Elevator Contractor
A modular elevator is the fastest and easiest elevator you’ll ever install. There are no rails to hang, cab to assemble, or unprotected heights to hang from. We’ve done all the assembly work; all you have to do is set it in place, connect it to the power source, and perform normal startup, testing and adjusting.
Here are the steps in the installation process.
Step 1: Obtain Permits
We will supply layout drawings after the customer approves the details of their elevator. Use these to apply for the required permits.
Step 2: Unload Truck
The truck will arrive with:
→ The modular elevator shaft (multiple pieces if taller tower)
→ The modular machine room (if ordered) OR a pallet with the tank and controller strapped to it
→ The rest of the “shipped separately” components strapped inside the hoistway closest to point of use.
If there is a modular machine room, have the crane unload it first and set it off to the side.
Have the crane rig the hoistway, lift it off the truck, and allow the truck to drive away. Remove the shipping brackets from the bottom of the hoistway (Phillips head screws). Have the crane upright the elevator and lower it into the pit

Step 3: Set and Plumb Hoistway
The hoistway structure is built perfectly square in the factory, and the rails are aligned and welded in place. It is secured in the pit by bolting it to cast-in-place anchor bolts. The hoistway “legs” are 1” shorter than the pit is deep to allow for leveling the hoistway inside an imperfect pit. Once leveled, non-shrink grout is packed under the base plates to support them permanently.Setting the Hoistway
Step 4: Install the Machine Room
If there is a modular machine room supplied, it has the same footprint as the hoistway and should be set next to or behind it. Level the machine room base plate and then attach to the slab with epoxy anchors (GC supplies).
If there is a site-built machine room, mount the power unit and controller in the room, and wire them together and to the disconnects.
Step 5: Install Hydraulic Lines
Pipe the jacks to the power unit as with any other hydraulic elevator. You supply the piping and fittings, as well as pipe stands and anchorage.
If there is a modular machine room, we optionally supply a pre-cut piping/fittings package. One piece of pipe is left long and ungrooved on one end so that you can cut it to precise length.
If the machine room is remote from the hoistway, coordinate in advance with the GC on how the piping and cable will be routed. Plan for underground raceways to be set before the pit is poured. Make sure nothing extends past the inside of the pit wall until after the tower is set.
Step 6: Connect Wiring
Option A: The traveling cable and hoistway cable are coiled up near the bottom of the hoistway. Unwrap both cables and feed them to the desired exit point, through the raceway to the machine room.
Option B: The traveling cable and hoistway cable are terminated in a junction box at the bottom of the hoistway, and extra lengths of cable are supplied. Cut the cables to the precise length you need and wire them between the terminal box and the controller.
With a modular machine room, all gutter connections are precut and supplied. With a site-built machine room, you supply the gutter and conduit from the hoistway to the controller, controller to power unit, and controller to disconnects.MMR Piping Wiring
Step 7: Start Up the Elevator
Ensure jacks are plumb and secured, fill the tank with oil supplied by installer, sequentially remove shipping brackets, power up the elevator and lift the car. Check for leaks, remove the final shipping brackets, and lower the car.Start Up
Step 8: Test and Adjust Elevator
Perform all normal tests and adjustments as with any other newly installed elevator.
→ Run on inspection
→ Install selector tape, adjust magnets to set floor levels
→ Adjust doors
→ Run on automatic
→ Adjust valve
→ Connect and test smoke detector and fire alarm
→ Connect and test phone line
The elevator has not been powered up in the factory, so full testing and adjusting must be performed in the field. This includes doors, which are installed horizontally in the factory and thus cannot be fully adjusted until they are vertical.
Instructions on all equipment, as well as wiring diagrams, are contained in the Project Manual that ships with the elevator.
Step 9: Final Details
Install ceiling panels and lights in car.
Install light bulbs and guards in pit and cartop.
Give GC a punch list of any outstanding items that must be complete prior to inspection.
Step 10: Inspection
Schedule and perform inspection.
Turn elevator over to customer.
Arrange for ongoing maintenance to preserve the warranty.
