From the Manufacturer: 5 Expert Maintenance Tips to Maximize Your Hydraulic Puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner's Lifespan

On any overhead transmission line (OHTL) or underground cable laying project, your equipment's reliability is non-negotiable. Downtime on a hydraulic puller or Tensioner doesn't just stop one machine; it can bring the entire project to a halt, costing valuable time and money.

As a prominent manufacturer of this equipment for decades, we've seen what separates a machine that lasts 5 years from one that lasts 20. Based on the most common questions our service department receives, here are 5 expert tips from Ningbo Changshi to maximize your equipment's uptime and lifespan.

1. Treat Hydraulic Fluid Like Gold The hydraulic system is the lifeblood of your machine. The #1 cause of failure we see is contaminated hydraulic fluid.

• Check Levels Daily: Start every day by checking the fluid level.

• Watch for Leaks: A small drip is a warning sign. Fix it before it becomes a major failure.

• Follow Filter Schedules: Clogged filters force the pump to work harder, leading to burnout. Change hydraulic filters exactly as the service manual recommends.

2. Don't Guess on Grease We often see questions on forums like, "What color grease should I use?" Grease color is not a specification. Using the wrong grease (e.g., a simple chassis grease on a high-load bull-wheel bearing) will lead to rapid failure. Always use the specific type and grade of grease recommended in your owner's manual for different components.

3. Inspect Your Bull-Wheel Grooves Your tensioner's bull-wheels are what protect the expensive conductor. If the nylon or steel grooves become worn, chipped, or develop burrs, they can permanently damage the conductor. Inspect the grooves regularly and replace worn liners immediately.

4. Respect the Brakes and Controls Before every pull, test your control systems. Ensure the emergency stop functions correctly and that the brakes are responsive. If a tensioner is "stuck" or "won't release," it's often a sign of improper pressure release procedure. Never force a control; review the manual's decompression and shutdown steps.

5. Keep it Clean This isn't just about appearance. A clean machine allows you to spot problems—like a hairline crack, a loose bolt, or a new oil leak—before they become catastrophic failures. A regular cleaning schedule is one of the cheapest and most effective forms of preventative maintenance.
