Rig-Release®
Remote Releasing Hook — Consider The Possibilities... |
|
Work faster
and safer on your next challenging job
and release your rigging remotely. |
|
|
|
Can
the load be released accidentally?
When used properly the Rig-Release® can not be
accidentally released under load. |
Why
does the Rig-Release® Hook have a minimum
capacity?
In order for the safety mechanism (LOCK & CAPTURE)
to work, you must be lifting at least the minimum stated
capacity on the Rig-Release® Hook being used. |
|
|
|
Why
can’t the Rig-Release® Hook be released
under load?
Once a load is applied to the Rig-Release® Hook, it’s
Inner Body Assembly sets into a “LOCK & CAPTURE”
position and can not be released. Refer to page 5
for details. |
|
|
|
Where
can I get the Rig-Release® Hook inspected
or serviced?
Only at the factory in Rockford, Illinois. |
|
|
|
Can
I choke loads and use the Rig-Release® Hook?
Yes, a catch sling is required in addition to the load sling.
Refer to "Rigging The Rig-Release Hook - Choker Hitch" section
below for details. |
|
|
|
Do
I still have to unhook the rigging from the load?
No. By design, a properly rigged Rig-Release® Hook
removes the rigging from the set load when the crane
hook is raised up. |
|
|
|
Can
I pick up a load at full rated capacity using
only the strip sling hook on the Rig-Release® Hook?
Yes, the Rig-Release® Hook is designed to support the
full rated capacity from either attachment point. |
|
|
|
Does
the released rigging fall to the ground?
No. A properly rigged Rig-Release® Hook has one
end of the rigging attached to it at ALL TIMES. |
|
|
|
|
|
|
|
Can
I use it with all types of slings?
It is recommended that only wire rope slings of the proper
rating and capacity are to be used with the Rig-Release®
Hook. A nylon sling or chain could be used if they have
an oblong attached to them, consult factory for details. |
|
Why
is a wire rope sling attached to the
Rig-Release® Hook in TWO places?
One end is for its release from the Rig-Release® Hook
and the other end holds the rigging so that it can be
stripped from the load and not fall to the ground. |

|
|
|
 |
|
|
|
As
soon as the load is applied to the Rig-Release® Hook, the Inner Body
travels DOWN which is the
LOCK & CAPTURE position. In this position, the load CAN NOT be released.

Releasing
The Rig-Release® Hook |
|
|
|
|
|
 |
Once
the load is set and the crane line is slack, the Inner
Body Assembly can travel up. Now releasing can be
accomplished by pulling on a rope laynyard (Manual
Units) or pushing a button (Radio Controlled Units). |

Questions
on Manual Units
(Rope Lanyard controlled) |
|
|
|
On
the Manual Unit, which is rope
lanyard controlled, if the rope gets
hung-up, will it release the load?
No, the rope has a breakaway chain
which will yield and break if excessive
force is applied. This protects the
Rig-Release® from severe damage.
Even if the breakaway chain was
removed, no amount of force on the
rope will allow the hook to release
under load. |
 |
|
If
the rope breaks, how do I release
the load?
You would have to do this manually,
by going up and releasing the rigging
and bringing the Rig-Release® Hook
to the ground for proper repair. |

Questions
on Radio Controlled Units |
|
|
|
|
|
|
What
is the range or distance of the Radio Remote Control
(Transmitter)?
The Rig-Release® Hook will work up to 400 feet with a clear line of
site.
Field conditions, type of rigging used, weather, and battery charge can
also
affect performance. |
 |
|
|
|
If
I accidentally push the “RELEASE” button on the transmitter,
what happens?
Nothing! To activate the Rig-Release® Hooks releasing mechanism, two
buttons need to be pushed in the proper sequence. The first button is the
“ARM” button and the second is the “RELEASE” button.
They must be
pushed in this order. |
|
|
|
If
I accidentally push the “ARM” button and then accidentally push
the “RELEASE” button, can I accidentally disconnect the rigging?
The two button release procedure sequence is timed. Once the “ARM”
button
is pushed, you have only 10 seconds to push the “RELEASE” button.
After 10
seconds, the transmitter is timed out and you must start the release sequence
from the beginning. |

|
|
|
|
|
If
both buttons were accidentally pushed in the right order and
within 10 seconds would the load release?
When properly loaded, the Rig-Release® Hook is in the LOCK &
CAPTURE position and the Lift Arm and Mechanical Release Button
are physically blocked and can not open. |

Are
there different frequencies for different hooks?
All standard Radio Controlled Rig-Release® Hooks work on the
same frequency which is 418 MHz*. This allows for the controlled
release of multiple Rig-Release® Hooks using a single transmitter
(refer to Instruction Manual). |

How
long does the battery last?
Generally a battery will hold its charge for an eight hour shift,
but it depends upon the lifting cycle. All Radio Controlled
Rig-Release® Hooks come with two rechargeable batteries. |
