PAYLOAD CONSIDERATIONS
The PMXYZ Series instruments have a 20# equipment payload for vertical
operation (NOT inverted). This payload is based upon the total load on the
traveling flange with the base flange securely attached to the customers
chamber, providing a strong and stable mounting. The payload center of gravity
must be within the diameter of the traveling flange OD (Normally 2.75") and
within 8" of the flange face.
Please consult the factory if your application requires:
Payload greater than 20#
Center of gravity beyond above limits
Mounting orientation other than standard vertical, such as angled, horizontal,
inverted.
If the manipulator is to be used with the Z axis horizontal, the NOW vertical
micrometer MUST be under the gradational load. The Z axis must be
UNDER the drive axis.
