3. INSTALLATION
LANTEC recommends that the mounting and installation of the winch be carried out by
a qualified millwright.
The winch foundation is extremely important for proper winch operation. This
foundation must be planar and completely flat, and must be rigid and unyielding under
full winch load.
It is important to note that LANTEC machines and line bores its winch
housings including the winch mounting pads. This is to ensure that the
winch mounting pads are planar and parallel to the axial alignment of the
winch drum bearings. Therefore the winch housing must be installed onto
a foundation which is within the tolerances specified or the winch drum
bearings will become misaligned, causing premature failure.
One method to mount the winch :
1. Sling it on the drum and carefully lower the winch until three of the four winch base
pads just contact the foundation
NOTE: Hardened flat washers must be used under the bolt heads;
DO NOT use lockwashers
2. Install mounting bolts, Grade 5 minimum, on the three pads in contact with the
foundation and torque them to their correct value
3. Measure any gap between the fourth pad and the foundation with a feeler gauge
NOTE: The maximum misalignment of 0.002"/ft. from mounting hole to mounting
hole on either end of the winch measuring perpendicular to the drum
4. If the misalignment is outside of tolerance then the gap between foundation and the
fourth pad must be shimmed to correct this
5. Once the correct shims are in place, the remaining bolt(s) can be installed and
torqued to their correct value.
DO NOT WELD TO ANY PART OF THE WINCH
Do not operate or perform any lubrication, maintenance or
