CARRIAGE

The carriage is made up of a series of welded
components that move up and down in the inner mast
channel, with the help of load and side rollers.
The Mast on the 2-3.5T 2FFL has a total of three
groups of composite load rollers and two groups of
standard load rollers. At the mast maximum height,
two standard load rollers will extend out of the top of
the inner channel.
The fork is locked inside the groove on the bracket
using lock pins, and the spacing of fork can be
adjusted manually

ADJUSTMENT OF LIFTING SYSTEM

1. Once carriage is placed into the inner channel of
the mast, set the carriage height by placing a
gauge block that is 76 mm (2.3 in.) high to set
carriage height.
Drop the fork to the ground, and adjust the nut on
the lift chain's upper end to ensure that there is
the distance A between the load roller and the
inner mast. See Adjustment of Lifting System
