4000 SRM 340 Forks Replacement
Forks Replacement
The identification of a fork describes how the fork is
connected to the carriage. The series of lift trucks
that use this mast normally have hook forks. See
Figure 6. Pin forks are available on the larger capac-
ity lift trucks in this series as an option. Pin forks
are fastened to the carriage with large fork pins. See
Figure 8.
Hook forks are connected to the carriage by hooks
and lock pins. These lock pins are installed through
the top fork hooks and fit into slots in the top carriage
bar. Separate the forks as much as possible for maxi-
mum support of the load. Hook forks will slide along
