INTRODUCTION
GENERAL
This section has a description and the repair procedures
for the single and double–reach carriages on 2–stage or
3–stage masts of the N30–40–45FR lift trucks.
DESCRIPTION
(See FIGURE 1., FIGURE 2. and
FIGURE 3.)
The reach carriages are used to extend the reach of the
carriage. There are two types of reach carriages. There
is a single–reach carriage with one set of scissor arms.
The other carriage has two sets of scissor arms for dou-
ble–reach. Both carriages have a tilt cylinder to tilt the
forks. Each carriage can also have the optional side–
shift function. The parts of the reach carriages are
shown in FIGURE 1. The inner and outer frame assem-
blies are connected by a scissor linkage. The top of the
scissor arm weldment at the inner frame is fastened to
the top of the inner frame by pins. The top of each scis-
sor arm at the outer frame or apron is fastened to the top
of the frame or apron by pins. On double reach units,
the ends of each set of scissor arms and scissor arm
weldments are fastened together by studs with bear-
ings. The bearings on each pin or stud permit the arms
to pivot. Large bearings at the center pivot of each scis-
sor arm and scissor arm weldment also permit the link-
age to pivot.

The bottom arms at the outer frame or apron and the in-
ner frame have load bearings that fit into channels in the
frame assemblies. The load bearings permit the ends of
the arms to move vertically in the frame channels. The
side–shift carriages have another frame that can move
sideways on the apron. Two bearing blocks at the top of
the
