New Lubrication System Protects Against Friction Wear &Corrosion

       The pendant lines that support the craneboom were of major concern because they had to be completely reliable for theperiod of the equipment's lease which could be up to two years. Lubrication isa necessary part of the maintenance process because it helps prevent wearcaused by the movement of the internal wires against each other. Lubricationalso helps prevent deterioration of wire rope due to rust and corrosion.Lubricant is squeezed out of the rope as it runs over sheaves under tension,washed off by rain and if it is a dry film, it will flake.

    In the industry, most wire ropemaintenance is done manually by hand or mechanically through a spray system.They used a pneumatic spray method, as it was believed that maximum penetrationcould only be achieved with thin wire rope dressings.

   Even though both the hand and spray methodwere the best methods available at the time, neither offered consistentprotection against friction wear or corrosion of the individual wire strands ofa wire rope. The manual hand method, where high viscous lubricant is applied tothe surface of the wire, only served to trap any corrosion inside causingmoisture, while the spraying method which utilized thin lubricants through aspray nozzle applicator, provided minimal fluid film barrier between individualwire strands allowing excessive friction wear. In addition, there was a gooddeal of lubricant loss due to drainage and misting and there was no way to beassured that 100% lubrication had occurred.

    The need for a more thorough anddependable method of lubrication was proven when one of their rental crane's pendantssnapped on a job site causing the boom to drop. Even though the surface of thewire rope showed lubricant residue, the core of the subject wire rope hadturned to powder. The customer had used the aforementioned methods oflubrication. Fortunately, damage was minimal and there were no injuries.

UBL SOLUTION

As a consequence, They began using the pressurelubrication method of wire rope lubrication by designing a system which wouldgive maximum penetration and coating of both low and high viscosity lubricantsinto the internal strands of their cranes' wire rope.

    This lubricant delivery system centersaround UBL pump packages, specifically grease pumps. The pump packagesdelivered the wire rope lubricant from the lubricant container to the lubricationcollar which clamped-around the wire rope to be lubricated.

TESTING

BENEFITS

    UBL's grease pumps were chosen for thissystem because of the consistency of the pump's performance in a wide range ofmaintenance applications coupled with the quick response of UBL's managementand technical support group to their needs. This has helped them give quick serviceresponse to their customers worldwide. The dependability and simplicity of thesystem has changed the way wire rope maintenance is performed worldwide. Inputfrom hundreds of users has confirmed that when used properly, this wire ropelubrication system will significantly increase the life of wire rope.

    These systems have been designed so thatin only one application, wire rope can have its surface and grooves scrapedclean of product buildup and grit while at the same time any new lubricant isuniformly applied to the newly cleaned surface and injected into the very core.Moisture trapped in the internal strands is forced out and replaced with thenew lubricant. All systems are compatible with low as well as high viscositylubricants.
