SAFETY DEVICES 

 

There are safety devices on the IC-35 to maintain control of a load in case of power or 

hydraulic line failure or human error.  The operator should understand the function and 

operation of these devices, so that a continual check on their performance can be made. 

 

OUTRIGGER CYLINDER CHECK VALVE: 

A double-acting check valve is flange-mounted on each of the outrigger cylinders.  This 

valve holds the outrigger in the extended position should power or hydraulic line failure 

occur.  This valve has no adjustment.  If an outrigger creeps up while supporting a load, 

there  is  an  internal  leak  in  the  valve  or  in  the  outrigger  piston  seal.    In  either  case, 

maintenance is required. 

 

BOOM ELEVATION CYLINDER HOLDING VALVE: 

A single-acting holding valve is built into the cylinder barrel.  This valve holds the boom 

in the elevated position should power or hydraulic pressure line failure  occur.  This valve 

is adjustable to hold the desired load.  If the boom creeps down with loads to maximum 

capacity, this valve should be adjusted.  If adjustment fails to correct the problem, there 

is an internal leak in a holding valve or a hydraulic cylinder.  Refer to the maintenance 

instructions. 

 

BOOM EXTENSION CYLINDER HOLDING VALVE: 

A single-acting holding valve is flange-mounted to the cylinder rod end.  This valve holds 

the  cylinder  in  the  extended  position  should  power  or  hydraulic  pressure  line  failure 

occur.  This valve is adjustable to hold the desired load.  If the boom creeps in under 

load, this valve should be adjusted.  If adjustment fails to correct the problem, there is an 

internal  leak  in  the  holding  valve  or  the  hydraulic  cylinder.    Refer  to  the  maintenance 

instructions.  

 

ANTI-TWO-BLOCK DEVICE: 

The anti-two-block device prevents damage to hoist rope or machine components from 

accidentally pulling load hook against boom tip.  There is a pivot arm at the boom tip that 

is moved upward by the load hook as it approaches the boom tip.   An electric switch 

connected  to  a  hydraulic  solenoid  valve  dumps  the  HOIST  RAISE,  TELESCOPE 

EXTEND BOOM LOWER, SWING LEFT and SWING RIGHT circuits.  No other circuits 

are affected.  These circuits are returned to normal operation by operating the HOIST 

LOWER, TELESCOPE RETRACT or BOOM RAISE control. 

 

An emergency override switch is provided so the boom can be operated in case of 

system failure.  This key-operated switch is located under the instrument panel. 

 

 

W A R N I N G 

We recommend the emergency override switch be used with discretion.  Improper 

or  careless  use  of  this  switch  can  cause  damage  to  the  crane  and  endanger 

people and property.  The operator who uses this key in an emergency should use 

good judgment. 

 

 

W A R N I N G 

Even  though  the  crane  is  equipped  with  an  anti-two-block  device,  we  strongly 

recommend that the operator always watch the downhaul and stop lifting before 

two-blocking occurs.  Two-blocking can break the load hoist rope and let the load 

fall.  This could cause death or serious injury.
