3） Track Shoe
The track shoe is made of high-strength and high wear-
resistance material, with its tension regulated by the
hydraulic jacks after installation. The ideal tension can be
achieved through adjusting the position of gaskets.

Operation Devices

1） Boom
The main chord pipe is made of high-strength material.
■
And the boom frame is of lattice the space truss
structure with the constant cross section at middle of
boom and with the variable cross-section at two ends.
Factory standard sections include: Boom base 10m,
■
transition insert 6m, boom head 1m, intermediate
section 3m×1, inter mediate section 6m×1 and
intermediate section 12m×5.
The boom length can be variable between the basic
■
boom (20m) and longest length (86m), which is
increased by 3m.
The 2.0m boom extension can be installed not only on
■
the boom head but also on the luffing jib head.
2） Fixed Jib
The main chord pipe is made of high-strength material.
■
And the boom frame is of lattice the space truss
structure with the constant cross section at middle of
boom and with the variable cross-section at two ends.
Jib top 6.5m, jib base 6.5m, intermediate section 6m × 1
■
and 11.5 m × 2; the usable fixed jib length includes 13m,
19m, 24.5m, 30.5m, 36m and 42m and the fixed jib can be
mounted on the boom of the length of 29~62m.
3） Luffing Jib
The main chord pipe is made of high-strength material.
■
And the boom frame is of lattice the space truss
structure with the constant cross section at middle of
boom and with the variable cross-section at two ends.
Jib top 6m, jib base 6m, intermediate section 3m × 1, 6m×2
■
and 12m × 3; the usable fixed jib length includes 21m,
24m, 27m, 30m, 33m, 36m, 39m, 42m, 45m, 48m,
51m, 54m, 57m, 60m and 63m the luffing jib can be
mounted on the boom of the length of 26~62m.
