6. Slowly lift the mast until just free of the mast saddles.
If necessary, lower the mast and adjust the sling as necessary to balance the
7. Ensuring the sling does not catch on anything, lift the mast without any sharp or jerking
motions until it is free of the shipping crate.
8. Slowly move the mast to the desired mounting location. The hoist operator should be
able to view the mast at all times to ensure the mast does not collide with any
obstructions.
9. Slowly lower the mast until the mast is on the mounting surface and the weight of the
mast has settled. Stop lowering the mast once the mast weight has settled.
10. Ensure the mast is temporarily secured to prevent it from tipping over during the
installation process.
The Will-Burt Company recommends keeping the shipping crate for transporting the mast, for
example if shipping the mast back to the factory for refurbishment.
Secure the Support Bracket Assembly
To secure the Support Bracket Assembly:
1. Carefully move the mast into position in the mounting location. Be certain to orient the
mast so the operator has a clear view of the hazard labels.
2. Ensure the mast is level in all directions. If necessary, shims may be added to correct
the alignment of the mast. It is necessary to check the mast in two places 90° apart
when leveling.
3. Determine the desired location for the Support Bracket Assembly. Refer to Section 2.4.1
for the minimum height of the Support Bracket Assembly on the mast.
4. Secure the Support Bracket Assembly around the Base Tube with the hardware
included. Shim as necessary to avoid overtightening the Support Bracket Assembly on
the Base Tube. This will damage the mast. The mounting hardware must include proper
means to resist vibration loosening such as thread-locking compound or locking
hardware. Torque to 245-290 in.-lb. (28-33 N-m).
5. Use the Support Bracket as a template to drill holes in the desired support structure.
Ensure the Mast System is level in all directions during drilling.
6. Loosely secure the Support Bracket to the support structure with six ⅜ inch (M10) sets
of customer-provided stainless steel hardware. Do not torque the hardware at this point.
This will be done later in these procedures. The mounting hardware must include a
proper means to resist vibration loosening such as thread-locking compound and/or
locking hardware.
