I recently acquired a 1985 LS98 for dragline operations at a small marina. This machine underwent a rebuild in the mid-2000s by Inman Texas and seems to be in excellent condition with less than 300 hours since the reconstruction. I am utilizing a Hendrix 1 1/4 yard drag with it. While I have operated several draglines in the past, I have not had experience with Link Belts. The clutches on the inhaul line of this machine do not seem to hold as well as I expected during aggressive digging, causing it to slip easily on hard cuts. The shoes appear to be in good condition with no signs of oil or grease. I am unsure if this issue is a characteristic of the hydraulic actuators or if there is a problem that needs addressing.
It is possible that the issue lies with the clutch adjustment or band centering at the "dead" end, if there is an adjustment available. My recollection vaguely suggests that there are two types of actuators: one for hoist and drag functions that engage quickly, and another for the swing function that engages more slowly.
I have ordered both a maintenance/adjustment and a shop repair manual for the machine, which should arrive within the next week. Once I have them, I can properly inspect the clutch settings with confidence. I don't want to make any adjustments without guidance until then, to ensure it is done correctly.
As a mechanical engineer with years of experience in machining and millwright work, I am eager to learn from someone skilled in adjusting these types of clutches and actuators. I am open to trying new methods and techniques in order to improve my knowledge and skills in this area.
If you're anything like me, you're always up for a challenge! Consider checking the clutch bands on the drum to ensure they are making full contact with the friction material. Look for signs of wear like hard and shiny surfaces, as this could be causing the issue. Let's dive in and troubleshoot together!
I have not had the chance to inspect it thoroughly yet. I briefly ran the equipment yesterday, but it was too dark to assess properly. I will be reviewing it on Monday to check the level of contact it is making and look for any signs of glazing.
Answer: Answer: The issue of the clutch slipping during aggressive digging on the LS98 Dragline could be due to various factors, such as hydraulic actuator problems, wear and tear on the clutch components, or improper adjustment of the clutch mechanism.
Answer: Answer: To address the inhaul clutch issues on the LS98 Dragline, you can start by inspecting the hydraulic actuators, checking for any signs of wear on the clutch components, adjusting the clutch mechanism if needed, and ensuring proper lubrication of the clutch system.
Answer: Answer: Regular maintenance of the clutch system on the LS98 Dragline is essential to ensure optimal performance. This includes checking for wear on the clutch components, maintaining proper lubrication, adjusting the clutch mechanism as needed, and addressing any hydraulic actuator issues promptly.
