The Full Certification Difference
A load test tells you the equipment held. It does not tell you what happened inside. A sheave is not a chain — you cannot see the internal components. That’s where full certification does what a load test cannot.
Bearing Failures: Sheaves require the manufacturer specified bearings and grease. Wrong grease or improper assembly can destroy bearings and cause failures in the field. Our inspection catches it before it goes back to location.
Hub Sealing: Sealed Sheaves must be properly sealed to ensure longevity. If the sealing caps are not fully seated, the bearing housing isn’t protected. We verify seating before final assembly.
Axle Nut Torque: The axle nut must be torqued to spec and secured with spiral pins. An under-torqued axle rotates, creating competing friction and bearing stress. We verify torque every time.
Cast Components: Cast aluminum parts require dye penetrant inspection to catch micro-fractures that are invisible to the naked eye and undetectable by load testing alone.
Assembly: Components put together incorrectly won’t always fail a load test. We check assembly against spec every time.
WTI Sets the Standard: WTI manufactures the world’s largest line of wireline sheaves and sets the industry standard for recertification. Mazzella is an authorized WTI certified service center and distributor — and we follow their exact process every time on every job.

Who We Work With
Mazzella Wireline Services works with the companies keeping wells running — wireline service providers, well intervention specialists, and oilfield services operators from the largest global names to regional outfits working a handful of districts.
You run wireline trucks, work completions, and keep wells producing through every stage of their life — from the Haynesville to the Permian to the Eagle Ford and beyond. When equipment comes back from certification, it needs to be right — a sheave that fails or paperwork that won’t hold up costs you a job and time you don’t have.
That’s the shop we built. Equipment done right, documentation that holds up, and someone who picks up the phone when it’s 2 a.m. and you’re stuck on location.
You don’t get days off. Neither do we.

Rigging Repairs and Inspections
Mazzella is a leader in rigging repairs and inspections. Mazzella employs an in-house team of certified inspectors that can provide documented rigging inspections that meet or exceed government requirements (OSHA and ASME).
Our inspections help you:
- Catch issues before they become accidents.
- Extend the usable life of your equipment.
- Provide you with documentation for OSHA compliance.
- Uncover repair and training opportunities that strengthen your safety culture.
Our inspectors conduct:
- Rigging Inspections: Covering all slings, shackles, hooks, spreader beams, lifters, and personal fall protection. Inspections are performed by certified technicians who tag, document, and deliver reports with clear recommendations.
- Overhead Crane Inspections: Our inspectors go up on the crane, not just ground-level. We check hoists, brakes, limit switches, and controls to ensure compliance with CMAA, OSHA 1910.179, and ASME B30.2 requirements.
- Fall Protection Inspections: We provide inspections for personal fall protection products, as well as engineered lifeline systems.
- Warehouse Racking Inspections: Identifying damaged uprights, overloaded beams, and unsafe configurations that put workers and inventory at risk.
Every repaired or recertified item comes with proper documentation, ensuring compliance with OSHA, ASME, and customer safety requirements
Fall Protection Solutions
Mazzella supports your fall protection needs with:
- Engineered Systems: Horizontal lifelines, rigid track systems, and custom anchor points.
- PPE: Harnesses, SRLs, lanyards, and rescue equipment.
- Inspections: Annual and periodic inspections to keep fall protection systems compliant.
- Training: Fall protection user and competent-person training.
- Rescue Planning: Site-specific plans to ensure quick, safe rescue in the event of a fall.
We can also inspect and repair retractable fall protection devices.
We partner with leading manufacturers to ensure reliability, such as 3M, Gorbel, Reid Lifting, TUFF BUILT, Tractel, Rigid Lifelines, and Safewaze.
And because we’re local, we can provide fast response for inspections, recertifications, and training—helping you meet OSHA and ANSI requirements without delay..
Training and Certifications
If your employees require specific training programs for OSHA compliance for overhead cranes, slings, hoists, or rigging hardware, we can assist in creating a safe and reliable workplace. Our trainers are accredited through Industrial Training International, Inc. (ITI) and train to OSHA and ASME standards.
Mazzella’s in-house training is all about the basics of lifting and rigging, getting your workers compliant. Our training focuses on four key departments:
- Rigging Training: Proper selection, inspection, and safe use.
- Overhead Crane Operator Training: Teaching OSHA/ASME compliance and practical operation.
- Signalperson Training: OSHA 1926.1428 compliant.
- Fall Protection Training: From basics to competent person.
- Custom Safety Programs: Tailored for your specific experience and needs.
Training is not only about compliance. It reduces accidents, lowers insurance costs, and creates a culture of safety. Companies that invest in training see fewer injuries, less downtime, and stronger employee engagement.
Through our partnership with Industrial Training International (ITI), Mazzella customers also gain access to some of the most advanced training programs in the industry.
Our local sales representatives can also work with you to schedule on-site training for operators, riggers, and safety professionals.
Custom Fabrication
We are more than a distributor—we build and repair custom assemblies to meet the specific demands of the oil and gas industry.
- Kelly Cables: Specialized cables for drilling applications in oil and gas.
- Spooling & Assembly: Custom wire rope and sling fabrication.
- Annealing Machine: In-house annealing capability to improve wire rope durability.
Below-the-Hook Lifting Devices
Some jobs have no off-the-shelf answer — a prototype lifting device, a non-standard assembly, a pick that has to be engineered from scratch. That goes to Mazzella’s in-house engineering team. They design custom below-the-hook lifting devices with 3D modeling and load analysis, built to ASME BTH-1 with documentation that holds up on location or in an audit. One senior engineer holds a seat on the ASME B30.20 subcommittee.
National Accounts
Companies often run crews across several districts, and each one usually buys its own way — different suppliers, different paperwork, no visibility into total lifting and rigging spend. Mazzella’s National Accounts program pulls that together:
- One agreement, one corporate point of contact, with local account managers in the facilities
- Standardized products, fewer suppliers, fewer purchase orders
- Quarterly business reviews with hard numbers on cost savings and service, against a baseline set up front
- Same certification quality and equipment standard at every location, in every basin
It doesn’t touch the local relationships. It adds a corporate layer so a company gets consistency across districts without losing the people who know their sites.
Frequently Asked Questions
Can Mazzella certify wireline equipment from manufacturers other than WTI?
Yes. Mazzella certifies wireline and well intervention equipment regardless of manufacturer. Certification is performed to applicable ASME standards, manufacturer specifications, and operator requirements. Equipment types we certify include sheaves, shackles, spreader bars, wire rope and chain slings, setting tools, wireline BOPs, lubricators, stuffing boxes, and related pressure control and downhole tooling components.
What is wireline equipment, and why does it require specialized certification?
Wireline equipment encompasses the overhead lifting and rigging gear, pressure control assemblies, and downhole tooling used by wireline service companies during oil and gas well operations — from completions and production logging to well intervention. Wireline equipment operates under significant load cycles, often in harsh conditions, with personnel working in close proximity. The E&P operators who own and manage wells set specific certification requirements for equipment before it is cleared for use on location — because a failure in the field means a stopped job at minimum, and a serious incident at worst. The certification standard is driven by the industry itself: operators specify the process and documentation they require, and wireline service companies are responsible for meeting it. A shop that understands those requirements — and the specific failure modes of wireline equipment — produces a different result than one running a generic rigging certification program.
What does it mean for wireline equipment to be “certified to location”?
When a wireline service company says equipment needs to be “certified to location,” it means the equipment must carry current certification documentation — typically within the last year for overhead lifting and rigging equipment — before the operating company will allow it on site. The certification package travels with the equipment. Company men and operator representatives review it on location to confirm the equipment has been inspected, load tested, and documented to the applicable codes before any work begins. This is why the documentation package matters as much as the physical inspection: it has to satisfy the person reviewing it at the wellsite, not just the technician who ran the test.
