Hoisting kit Mfr. Part # W38
-------------------------------------------------------------------------------------------------------------------------------------------
What’s included
-------------------------------------------------------------------------------------------------------------------------------------------
Spreader bar capacity info Spreader bar capacity is 2500 lbs. when lifted from center.
Additional capacity can be attained by attaching the picker by the holes at each end of the spreader bar, instead of the center hole.
Each fully assembled wall panel with legs and all primary components weigh approximately 150 lbs.
Example scenario, coupled sections: (6 panels) x (150 lbs) x (2 sections) = 1800 lbs.
-------------------------------------------------------------------------------------------------------------------------------------------
Important All of the presented instructions in the hoisting guide employ the hoisting kit shown above. This kit is designed to compliment
the INSCO System, but can be used in other applications if neccessary. Though the kit is not required, it is highly recommended for any operation looking to maximize the transport capabilities of their INSCO System. Anyone hoisting their
INSCO System without using this hoisting kit should use these instructions as an aid for proper setup.
The hoisting components shown above are also available individually from you INSCO System distributor.
Always wear hard hats and appropriate safety gear when hoisting.

Setup at well site
How to use a crane to set up pre-assembled wall sections that have already been delivered to the well site
-----------------------------------------------------------------------------------------------------------------------------------
Read prior to hoisting
1. The wall sections in this guide are identified as A & B, and there are two coupled sections.
2. Wall sections A & B need to be setup identically, except that section B needs the stabilizer strap pre-installed.
3. Hoisting a single wall section that is generally longer requires the use of the stabilizer strap. The stabilizer
strap should be pre-installed prior to delivering wall sections to the well site.
-----------------------------------------------------------------------------------------------------------------------------------
Helpful tips to consider prior to hoisting
1. When hoisting coupled wall sections, it’s recommended that the 32” hobble chain (included in
hoisting kit) is attached to help prevent the wall sections from spreading in the middle. Install it at
the centermost point, insert the hook on the end of
the chain into the small hole in the foot of the support leg on wall section B, then run it
underneath the wall and hook it into the foot on the opposite side on wall section A.
2. When hoisting wall section B it may be beneficial have pre-installed base stiffeners (W29) at the lifting points to help support the stabilizer straps. Install over the seam between two panels using tek screws.
3. When hoisting units with a crane a complete rail cap (W4 & W35) should be temporarily installed using 2 tek
screws (included in containment package) per 8 foot cap. Remove the rail caps to install the liner membrane, then fully reinstall after the liner membrane has been put in place.

Strategy & Site Preparation / 1
Before hoisting and setting the containment into place, it’s important to prepare on-site setup plans. Measure and
locate the perimeter of the containment area, using locating stakes to mark the corners. Then cross measure from corner to corner to ensure containment area is square.
-----------------------------------------------------------------------------------------------------------------------------------
16
Place coupled wall sections / 2
Place the first set of coupled wall sections as shown in the diagram below. Place the coupled walls so that wall section A is on the edge of the containment area, as it will not need to be moved again once in place.
At this point wall section A will be left at the primary location, and section B will eventually be separated and moved to the secondary location.
-----------------------------------------------------------------------------------------------------------------------------------
Un-couple wall sections / 3
Remove the clevises and lifting straps from the hoisting arms W31.
Disconnect hoisting arm W31 from lifting eyelet W30 on wall section B only, then flip the hoisting arm over
and leave hanging on wall section A.
Remove the wall end couplers.
Leave the lifting eyelets in place, as they will be used in the next steps.
-----------------------------------------------------------------------------------------------------------------------------------
17
Hook up spreader bar to wall section B / 4
With the spreader bar prepped for pickup, position it over the first pair of walls. Prepare to hook up wall section B.
Use 1 of the 4 lifting straps and clevises provided, hook it up to eyelet W30 on wall section B. Hook the remaining
clevises and lifting straps to the lifting eyelets on wall section B. At this point raise the spreader bar to create minimal tension on all 4 lifting straps.
-----------------------------------------------------------------------------------------------------------------------------------
18
Hook stabilizer strap to spreader bar / 5
At this point you will have the ratchet strap that was pre-installed at each end of the spreader bar. Feed the long end of the stabilizer strap through the ratchet so that it can be tightened. Tighten the stabilizer strap enough to keep the
wall vertical and stable when hoisting, while keeping tension on the load bearing primary lifting straps. Minimal tension on the stabilizer strap is required to keep the wall vertical.

Attach W8 main corner joint / 7
After wall section B is in the proper location, attach to wall section A with the W8 main corner joint. Connect
with the W5 & W7 wedge pins included in the containment package.
Also attach the W10 49” corner reinforcement angle while attaching the corner joint.
Attach W6 corner support bracket at the top of the corner before proceeding to the next set of walls.
-----------------------------------------------------------------------------------------------------------------------------------
Setup the remaining wall sections / 8
After the first two wall sections have been put in place, disconnect the spreader bar from the wall and move the crane
to the opposite corner (see diagram below). Setup the remaining two wall sections using the same steps as described
above.
-----------------------------------------------------------------------------------------------------------------------------------
You now have a fully enclosed containment area
