31. Anti-Two Block Panel is equipped with an
audio/visual anti-two block warning system de-
signed to alert operator of impending two-block
conditions (i.e., the hook or hook block is being
drawn into boom point sheaves). The vehicle is
equipped with a shut-off disconnect system on
the control linkage. It is activated when the hook
block contacts the anti-two block counterweight:
winch hoisting will cease, and boom will not
extend or lower; raising and retracting boom and
winch down functions will remain active. Ap-
propriate counteraction should be taken to pre-
vent two-blocking (Figure 4-12).

Anti-Two Block Warning Light is a visual
warning light to indicate approaching two-block
condition.
Anti-Two Block Audible Horn Warning
Switch is used to deactivate the audible warning
system while traveling.
Unwarranted use of BY-PASS
switch can result in damage to
the LRT 110 Crane and cause
DEATH or serious injury.
Anti-Two Block BY-PASS Switch allows an
operator to override the anti-two block system.
This then allows hook or block to be drawn
closer to boom point. It is recommended that the
BY-PASS switch be used only in cases of ex-
treme emergency. The operator must exercise
sound judgment.
32. Diagnostic Connector Panel is located in
rear of operator’s cab to plug in Vehicle Test
Module (VTM) to run STE/ICE tests. Fuel shut-
off switch is part of STE/ICE system and always
remains on unless it is used for STE/ICE tests
(Figure 4-13). Panel also has lubrication fitting
for turntable bearing. For lubrication instructions,
refer to Appendix B.
