SET-UP 1300A OPERATOR’S MANUAL
NOTE: The torque must be rechecked after the initial
operation of the crane. Be sure the cable clamp is
attached to the dead end of the cable only.
7. Start winding the cable onto the hoist drum. Maintain
about 500 pounds (250 kg) of tension on the cable.
8. Keep the cable wraps tight against each other when the
first half of the bare hoist is filling. The second half of the
hoist should wrap tightly because the fleet angle of the
cable tends to pull the cable to the center of the drum
thus wrapping tightly.
9. Continue winding the cable on the second, third and
fourth layer of the hoist. Keep the cable paying in
straight to the boom to avoid side loading the boom. The
preceding layers will wrap smoothly guided by the first
layer wrapping.
WIRELINE REEVING
Reeving for Wireline machines using a 2/3 line hook block is
shown in Figure 4-6. Install the Anti-2-block weight (1) on the
wedge socket (2) side of the hook block (3). Connect the
Anti-2-block chain (4) to the upper switch assembly (5).
WEDGE SOCKETS
To install a wedge socket:
• Make sure the wedge socket is the proper size for the
cable.
• Do not mix components of different wedge socket
manufacturers.
• The wedge socket must meet the requirements of the
wedge socket and wire rope manufacturers.
State and local laws may vary and require different
attachment methods depending upon work conditions. The
user is responsible for alternate attachment methods.
Terminator Wedge Installation
The 1300A is shipped with a terminator wedge socket which
is National Crane’s preferred type of socket (Figure 4-7).
Other wedge socket types are shown on page 4-10.
