How the Lubretec wire rope lubricator maximises safety and efficiency

The wire rope lubricator: your key to safer, longer-lasting operations

Wire ropes are a critical component in sectors like construction, offshore, mining, and logistics. Yet, their maintenance often remains a neglected aspect of daily operations - until something fails. That’s where Lubretec’s wire rope lubricator comes in.

This advanced system automates the lubrication process and ensures optimal penetration into the core of the rope, drastically improving both safety and cost-efficiency. But how exactly does it work, and why is it an essential tool for your operation?

What is a wire rope lubricator?

A wire rope lubricator is a maintenance device designed to clean and lubricate wire ropes in one continuous process. Instead of manual application, which often only coats the surface, the Lubretec system forces lubricant through the rope strands—right into the core.

It’s a closed system that eliminates wastage, protects the environment, and ensures the rope is fully protected, not just on the outside.

Why is deep-core lubrication so important?

Many operators assume that applying grease to the exterior is enough. But wire ropes don’t fail on the outside—they corrode from within. Moisture, salt, dirt, and other contaminants can penetrate deep into the rope if not adequately protected.

Lubretec’s system uses high pressure to push lubricant inside the rope structure. This method:

► Reduces internal friction

► Prevents corrosion

► Extends rope lifespan

► Reduces downtime due to unexpected failures

Reader question:
“Can I use the lubricator on ropes already in service?”

Absolutely. The Lubretec wire rope lubricator can be mounted directly on ropes in operation. Whether on cranes, winches, or hoisting systems, it works with minimal disruption and even offers a cleaning function that removes old grease and debris before re-lubrication.

Features of the Lubretec wire rope lubricator

Let’s break down the core elements that make this system effective:

1. High-pressure injection

The heart of the system is its grease injection block. It delivers lubricant at sufficient pressure to reach the rope’s core—even in compacted ropes.

2. Integrated cleaning

Before applying new lubricant, the system cleans the rope using specially designed scrapers. This ensures old, ineffective grease and contaminants don’t block fresh lubricant from reaching the core.

3. Universal mounting

The system is designed to be portable and adaptable. It can be clamped around ropes of various diameters (typically 8–64 mm) and fits into most industrial setups.

4. Eco-friendly operation

Its closed lubrication circuit means little to no grease spillage—protecting both the user and the environment.

Reader question:
“How often should I lubricate my wire ropes?”

Lubrication intervals depend on usage intensity and environmental conditions. However, regular checks and scheduled lubrication—especially before signs of wear or corrosion appear—are best practice.

As a rule of thumb:

Harsh environments (offshore, mining): Every 1–2 weeks
General industrial use: Monthly or based on cycles
After heavy loads or storms: Immediately inspect and, if necessary, re-lubricate

Advantages over manual lubrication

By automating and standardising the process, the Lubretec system drastically cuts maintenance time and improves rope performance.

Who should use a wire rope lubricator?

If your operation relies on wire ropes for critical functions, this device is a smart investment. 

Typical users include:

► Port and marine operators

► Offshore drilling rigs

► Mining companies

► Crane and hoist service providers

► Steel mills and production facilities

Lubricant usage estimate

Use the charts below to estimate the amount of lubricant required for various wire rope sizes.

These tables serve as a guide only and are the result of a test with a specific lubricant. Be advised that wire rope lubricant usage is dependent on a number of factors including:

• Lubricant in use
• Lubricant relative viscosity
• Rope speed
• Pump pressure
• Ambient temperature
• Rope type
• Rope age (new or used)
• Previous lubrication

Components of the Lubretec wire rope lubricator

To fully understand how the Lubretec system achieves such effective performance, it's important to know what it consists of. The complete system includes the following components:

1. Lubrication collar (split collar)

This is the main housing that encloses the rope during the lubrication process. Made of robust aluminium or steel, the collar opens and closes around the rope, creating a sealed chamber that contains the grease and prevents leakage. It is available in various sizes to accommodate rope diameters typically ranging from 8 mm to 64 mm.

2 Grease pump 

The grease pump delivers the lubricant under high pressure into the collar. 

► Pneumatic piston pumps – Best for regular industrial use with compressed air supply.

The pump is compatible with a wide range of lubricants, including biodegradable greases.

3. High-pressure hose

The hose connects the pump to the lubrication collar and is designed to handle the high pressures needed to push lubricant into the core of the rope. It’s flexible, reinforced, and resistant to abrasion.
