Concrete Requirements
Lift Concrete Requirements
Before installing your new lift, check the following.

1. LIFT LOCATION: Always use architects plans when available. Check layout dimension against floorplan requirements making sure that adequate space is available.

2. OVERHEAD OBSTRUCTIONS: The area where the lift will be located should be free of overhead obstructions such as heaters, building supports, electrical lines etc.

3. DEFECTIVE CONCRETE: Visually inspect the site where the lift is to be installed and check for cracked or defective concrete.

Specifications of concrete must be adhered to. Failure to do so could cause lift failure resulting in personal injury or death.

A level floor is suggested for proper installation and level lifting. Small differences in floor slopes may be compensated for by proper shimming. If a floor is of questionable slope, consider a survey of the site and/or the possibility of pouring a new level concrete slab.
  • DO NOT install lift on any asphalt surface or any surface other than concrete.
  • DO NOT install lift on expansion seams or on cracked or defective concrete.
  • DO NOT install lift on a second / elevated floor without first consulting building architect.
  • DO NOT install lift outdoors unless special consideration has been made to protect the power unit from inclimate weather conditions.
