Case Study: Wire Rope Replacement for Portal Crane
Tri-State Overhead Crane's service team changed out all of the wire ropes on the portal crane. The crane features four ropes on the hoist itself, with a hydraulic claw for a lower hook with a max capacity of 40 tons. And the ropes are required to be changed every six months. Our crew had 4 technicians involved in the process, with two guys up on the crane deck and two in a lift.
Taking it one rope at a time, the process started by removing a dead end and then safely lowering it to the ground with the lift. From there, the dead end was cut off, a new rope was attached using a Kellems grip, and the reeving was pulled by hand. This part of the process took the longest, as each rope was over 300 feet long.
The new live end was then taken up to the deck by our techs in the lift for installation. There, the two guys on the deck would loosen the drum clamps to remove the old rope and install the new live end as the two guys in the lift were feeding it up from below. This was a tricky process, as two ropes were being held down by the same clamps.
After the new live end was installed, the old live end would then be lowered using the lift. This process was then repeated for the remaining three ropes.
The customer was highly satisfied with the work, cleanup, and our crew's efficiency, especially considering that our techs had never worked on a portal crane before. Nevertheless, our team is always looking for ways to improve our processes and already have adjustments in place to make things more efficient for the next time.
