Our Products & Services
What We Do
LLTS provides specialized inspection, testing, certification, auditing, and technical support services that help organizations maintain safety, achieve regulatory compliance, and improve asset reliability across industrial, mining, and infrastructure operations. Our solutions are designed to reduce risk, prevent failures, and support operational excellence.
Magnetic Particle Inspection (MPI)
Mining operations depend on large, high-stress ferromagnetic machines. If surface or near-surface cracks go unnoticed, they can cause serious mechanical failures, expensive downtime, or even deadly accidents. MPI works as an early-warning system. The inspection service detects tiny fatigue cracks before they turn into major breaks, helping protect valuable equipment and ensuring mine operators meet their legal duty to keep workers safe.
In the Zimbabwean mining context, MPI is deployed across several critical assets:
- Winder and Hoist Components: Mine winders, or shaft hoists, are strictly regulated. MPI checks high-stress parts such as winder drum shafts, sheave wheels, brake linkages, and heavy-duty gears.
- Crusher and Mill Infrastructure: Ball mills, SAG mills, and jaw crushers endure intense cyclic loading. Technical teams use MPI to detect fatigue cracks in mill trunnions, girth gears, pinions, and crusher frames.
- Lifting Tackle and Structural Steel: National safety rules require regular MPI checks on cranes, gantries, shackles, and lifting hooks to catch fatigue before any structural failure.
- Heavy Earthmoving Equipment: Structural welds on dump truck chassis, excavator booms, and dragline buckets are regularly checked with MPI during major maintenance.
Ultrasonic Testing (UT) & Eddy Current Testing
Ultrasonic Testing is a precise Non-Destructive Testing (NDT) method that uses high-frequency sound waves to check the internal structure of solid materials.
Surface methods like Magnetic Particle Inspection (MPI) are useful for spotting cracks on the outside, but Ultrasonic Inspection services dive deep below the surface. In the Zimbabwean mining sector, UT is essential for predicting how long equipment will last and for preventing major failures.<br>
Replacing mining equipment and components in Zimbabwe often entails extended supply chain lead times and considerable capital investment. Ultrasonic inspection serves as a proactive measure, enabling mine operators to transition from reactive to predictive maintenance, thereby maintaining production continuity and ensuring workforce safety.
Key Uses of UT in Zimbabwean Industries and Mining
Mining machinery is subject to continuous abrasive and high-impact stress; internal defects are common. UT services are utilized for two primary functions:
- Thickness Gauging (Corrosion & Wear Monitoring)
- Slurry Pipelines & Chutes: Highly abrasive ore slurries constantly wear down the internal walls of pipelines. UT thickness gauging allows engineers to check the remaining steel thickness from the outside without shutting down or cutting open the pipes.
- Storage Tanks and Pressure Vessels: UT helps monitor wall thinning caused by corrosion or rust inside the tanks over time.
- Flaw Detection (Internal Integrity)
- Mill Trunnions and Shafts: The large shafts that turn ball and SAG mills can develop deep cracks inside from repeated use. UT can find these small cracks early, before they cause bigger problems.
- Heavy Welds: Techniques like Ultrasonic Testing (UT) are used to scan structural welds on heavy equipment (like excavator booms and dump truck frames) to find internal porosity or lack of weld fusion.
- Conveyor Pulley Shafts: The high tension in conveyor systems can cause shafts to weaken inside. Regular UT checks help make sure pulleys do not fail during use.
Liquid Dye Penetrant Inspection (DPI / PT)
LDPI is a non-destructive testing method widely used to detect surface-breaking flaws in non-porous materials. It is effective for identifying defects in both ferrous and non-ferrous materials, especially where fine cracking is a concern.
Key applications include:
- Fixed Plant Equipment: Inspecting structural welds, liners, and drive shafts of ball mills, SAG mills, and crushers used in high-impact ore crushing.
- Mineral Processing and Elution Plants: Checking for corrosion cracks and weld integrity in elution vessels, CIP/CIL (carbon-in-pulp/carbon-in-leach) storage tanks, and high-pressure piping.
- Haulage and Lifting Systems: Inspecting hoisting equipment, mine winders, overhead cranes, and gantries to meet statutory mine safety requirements.
- Yellow Fleet Maintenance: Assessing stress points and structural chassis welds on heavy earthmovers, excavators, and dump trucks.
Rope inspection services
We are committed to finding the best inspection methods for our customers. Our services continue to grow, and we offer custom solutions tailored to your needs. Regular inspections using advanced techniques improve safety and make maintenance planning easier. By spotting problems early, you can prevent expensive downtime and help your equipment last longer. We also suggest scheduling more detailed inspections from time to time. Using data analytics in our inspections helps you track rope conditions and predict rope useful life over the long term. This information helps you decide when to repair or replace ropes, which can make your operations run more smoothly.<br><br>
The Electromagnetic (EM) Wire Rope Condition Assessment Service employs a non-destructive testing (NDT) method to evaluate both the internal and external condition of steel wire ropes. This service is critical in high-risk, high-load industries, including mining (winder ropes), construction (cranes), and elevators, where wire rope failure can cause catastrophic accidents.
Key Advantages of the Service
- Safety Assurance: Detects hidden internal wire breaks and core corrosion that are not visible to the human eye, thereby reducing the risk of sudden rope failure.
- Regulatory Compliance: In the Zimbabwean mining industry, safety regulations mandate periodic electromagnetic testing as a statutory requirement for critical lifting and winding equipment.
- Optimized Maintenance: Provides detailed information about rope wear, so maintenance teams can focus on lubrication or plan replacements during scheduled downtime and avoid emergency repairs.
Wire Rope Installation and Maintenance
Because wire ropes serve as the literal lifelines for underground hoisting (winders) and material transport, rope installation and maintenance must be strictly supervised to prevent catastrophic structural failure. A qualified person should always handle or supervise the rope's installation. If the process is not properly supervised, it can cause serious injuries to both those nearby and those working directly with the rope.
- Even high-quality rope can fail early or not work as well if it is not handled correctly. Small mistakes like winding the drum incorrectly, misalignment, or using the wrong tension can lead to serious problems. To help prevent this, we provide on-site supervision for installations ranging from simple winches to complex multi-drum winding systems, delivered by experienced rope specialists as part of our service.
- We offer comprehensive wire rope maintenance to extend rope lifespan, ensure safety, and optimize equipment performance. Our services include re-lubrication, re-terminating, repairs, sheathing, socketing, slip and cut, and rope splicing. We also perform system maintenance, such as re-tensioning ropes, inspecting and repairing rope accessories and attachments.
