Raising the Crosstubes
You need to manually raise the Crosstubes, which makes it easier to complete the rest of the
installation tasks. The Crosstubes need to be raised the same height, to the same Safety Lock.
⚠
WARNING Use care when raising the Crosstubes, as the Posts are not anchored in place at
this point. Dropping or knocking over the Posts may cause permanent equipment
damage or serious personal injury. The Crosstubes and Posts are heavy; do not lift
without assistance. BendPak strongly recommends having at least two people
work together to raise the Crosstubes.
To raise the Crosstubes :
1. Use a Forklift or Shop Crane to carefully raise each Crosstube.
You want to raise the Crosstubes at least two feet off the ground, to have enough room to work
under it, making it easier to route the Lifting Cables and Lines.
Important :
The Slack Safeties cannot be engaged as you continue with the
installation . Because the Cables are not in place yet, the Slack Safeties are going to
engage when you manually raise the Crosstubes. You need to disengage them after
you have raised the Crosstubes. The Primary Safeties are not impacted; they will
engage normally when you manually raise each Crosstube, which is what you want.
2. To disengage the Slack Safeties after raising a Crosstube: raise and hold one end of a Crosstube
so the Primary and Slack Safety Locks are disengaged, push and hold the Sheave in towards the
Ladder and the back of the Post (this moves the Slack Safety Lock so it cannot to engage), lower
the end of the Crosstube, then release the Sheave or Steel Piece.
3. Disengage the other three Slack Safety Locks as done in Step 2.
4. Once both Crosstubes are in position,
all four Primary Safeties are engaged
, and all four
Slack Safeties have been disengaged , you can continue with the installation.
