Paccar Braden PD12C - Recommended Fastener Torque; Wire and Synthetic Rope Installation

9
RECOMMENDED FASTENER TORQUE
Higher or lower torques for special applications will be specied such as the use of spanner nuts, nuts on shaft ends,
jam nuts and where distortion of parts or gaskets is critical.
Lubricated torque values based on use of SAE 30wt engine oil applied to threads and face of bolt or nut.
Avoid using thread lubricants (such as anti-seize compound) as the applied torque may vary by 10-40%, depending
upon the product used.

WIRE AND SYNTHETIC ROPE INSTALLATION
This document provides instructions on installing wire and synthetic rope using various anchoring methods.
! WARNING !
Wire and synthetic rope anchors alone are not designed to
hold rated loads. Loads applied directly to the anchor may
cause the rope to pull free and result in the sudden loss of
load control, property damage, serious injury or death.
! WARNING !
A minimum number of ve wraps of rope must be on the
drum to handle full rated load.
SETSCREWS — WIRE ROPE
If the drum is designed with a cast-in, pass-through hole with 2 setscrews, follow these steps:
1. Determine the proper direction to wrap rope onto the drum.
2. Insert rope into the anchor hole until it is even with the other end of the hole.
3. Coat 2 anchor setscrew threads with antiseize compound and then tighten to recommended torque.
4. Wind rope onto the drum.
WEDGE ANCHOR — WIRE ROPE
If the drum is designed with an anchor pocket, follow these steps:
1. Make sure the anchor pocket and wedge are clean and dry. The end of the wire rope being anchored to the
drum must be clean and dry and not frayed. Anything on the end of the wire rope to keep it from fraying (i.e.
tape or wire) must not be in contact with the wedge when the installation is complete.
2. Take the free end of the wire rope and insert it through the small opening of the anchor pocket.
3. Loop the wire rope and push the free end about 3/4 of the way back through the pocket.
