Attention: It is the customer's responsibility to ensure the following steps are completed before the
service representative performs the tie-down procedure.
Note: To accommodate a floor with a depth of more than 16 inches, a steel beam or a steel channel
adapter for mounting the subfloor eyebolts are required. The customer must supply the floor
eyebolts.
Consider the following when preparing the floor for tie-down:
v The hardware is designed to support a frame weighing no more than 2636 pounds.
v The estimated maximum concentrated load on one caster for a 2636 pound-system is 900 pounds. For
a multiple system installation, it is possible that one floor tile will bear a total concentrated load of 1800
pounds.
To install the eyebolts, do the following:
1. Obtain the service of a qualified structural engineer to determine appropriate installation of the
eyebolts.
2. Consider the following before installing the eyebolts:
v Floor eyebolts must be securely anchored to the concrete floor.
v The minimum height of the center of the internal diameter is 1 inch above the concrete floor surface.
v The maximum is height 2.5 inches above the concrete floor surface. Higher than 2.5 inches can
cause excessive lateral deflection to the tie-down hardware.
v The eyebolt's internal diameter should be 1 3/16 inch, and each eyebolt should be able to withstand
2700 pounds. The customer should obtain the service of a qualified consultant or structural engineer
to determine the appropriate anchoring method for these eyebolts and to ensure that the raised floor
can support the floor-loading specifications.
3. The plan for installing four eyebolts positioned to match the dimensions is given in the following
illustrations.
