Testing / Checking the Travel of the Sling
• With a running sling, the next step is to carefully move the sling up and down the shaft
from bottom to top and check for any issues with door opening locations and running
gap, wall clearances, and that the sling travels smoothly and quietly up and down the
rails
• This procedure also allows the opportunity to check the hydraulic power unit (H2) is
functioning properly by running the sling up and down, fast and slow. Fine-tuning of
acceleration and down speeds will need to wait until we have some more weight on the
sling
• If a hard stop has been specified for your project it should be installed at the top of the
rails before attempting to fully extend the cylinder
Procedure:
•
Using the remote, carefully move the platform up and down the shaft documenting the
following
o
The setback at each landing is 6inch
•
If any of the measurements are not as per your project’s final drawings, you will need to
try and find the best possible location for the floor or identify changes that need to be
made to the shaft or the landings
• Move the sling up slowly until the cylinder is fully extended
• The cab floor (C1) should be 3 inches past the landing floor (plus or minus a ¼ inch)
This is your over travel. You will need to account for the flooring to be used in the cab
and at the landing:
o If the cab floor is 3 ¼ to 6 inches above the landing floor
a. Move the cab to the bottom landing
b. Adjust the nuts on both of the jack-post shackles down 1/2 the extra
distance. This will lengthen the ropes and solve the issue
Example:
The over travel is 5 inches. 5-3= 2, therefore the over travel is 2 inches too
much. The wire ropes will need to be lengthened by 1 inch to compensate; therefore, the
shackle nuts will need to move down 1 inch
o If the cab floor is between 1 inch below the landing floor to 2 ¾ inches past the
floor
a. Move the cab to the bottom landing
b. Adjust the nuts on both of the jack-post shackles up 1/2 the extra
distance. This will shorten the ropes and solve the issue
Example: The over travel is only 1 inch. 3-1= 2, therefore the over travel is 2 inches
little. The wire ropes will need to be shortened by 1 inch to compensate; therefore, the
shackle nuts will need to move up 1 inch
• If the over travel is off by more than 6 inches in either direction, the sheave hits the sling
before the cylinder is fully extended, or the cab touches the ceiling of the shaft before
the cylinder is fully extended, document any measurements that differ from your
projects final drawings and call Technical Support
• Level and secure the cab floor
