SECTION 1:
Safety
OPERATOR CONTROLLED SAFETY KNUCKLE
The attachment can only be disconnected completely from the I-LOCK Coupler after the intentional operation of the
Lock-Out switch which activates the
PRIMARY WEDGE
and
SAFETY KNUCKLE
. The I-Lock controller has a built in
time delay, which allows a fixed timeframe to disengage the attachment. After the time elapses the buzzer tone slows
and the safety knuckle will automatically reset. If the attachment
has not
been removed completely the automatic
reset of the safety knuckle will render the attachment into a safe situation again. If the attachment
has
been removed
the automatic reset of the safety knuckle ensures that the coupler is ready to reconnect to the next attachment.
WEDGE LOCKING PRINCIPLE
Another safety feature of the I-LOCK Coupler is the Wedge Locking Principle. The locking principle of the primary
wedge provides at least 2.5 times the locking force compared with a swinging jaw coupler. This assures that both
attachment pins are locked firmly to the coupler body minimizing the wear in the locking area of your coupler.
1.1 INTEGRATED DESIGN FEATURES:
The I-Lock Coupler has been designed to operate on the carrier machine’s
MAINS PRESSURE
supply.
The I-Lock Controller mounted within the coupler electrical circuit consists of a PIC which controls the I-Lock Control
Valve function. It also controls the warning buzzer and the I-Lock Safety Knuckle timeout feature. The electrical circuit
is protected by a 10 Amp fuse.
The I-Lock Control Valve controls the oil pressure and oil flow to the coupler for both the Primary Wedge function AND
the Safety Knuckle function.
The I-Lock Control Valve is only energized to release the attachment. This will ensure that in the event of an electrical
failure the primary locking mechanism and safety knuckle will stay in the locked position.
The warning buzzer is present to alert the operator that the electric circuit is live and the attachment can be released.
The warning buzzer has three distinctive frequencies which alerts the operator of the “mode” in which the coupler
locking sequence is in during the attachment change over process
The unique one piece hydraulic cylinder body eliminates port welding and potential feeder tube damage. Integrated
into the cylinder is a ‘Pilot Operated Safety Check Valve” which locks the pressure in the extend side of the cylinder in
the event of hose failure anywhere in the coupler circuit. In addition, on the larger models, an internal pressure relief
valve is fitted to the cylinders to protect against the potential of mechanically induced pressure spikes.
