Mazzella is a regional 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. 

• 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. 

We offer: 

• Preventive maintenance designed to align with outage schedules. 

• Emergency crane and hoist repair available 24/7. 

• Crane modernizations and upgrades (drives, controls, safety systems). 

• Parts sourcing and installation for all major OEMs, so you can expect fair pricing and quick turnaround times.

Our service technicians are independently trained and certified for expert maintenance and repair to keep your overhead crane equipment running. Our techs specialize in solving complex problems in emergency situations so you can avoid long downtime.  

Falls remain one of OSHA’s “Fatal Four” causes of workplace injuries. In steel plants, utilities, and construction, protecting workers at height is a top priority. 

Mazzella supports local companies 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 

• 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. 

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 Tier-1 suppliers, construction contractors, and steel plants. 

Companies that invest in training see fewer injuries, less downtime, and stronger employee engagement. 

Our local sales representatives can also work with you to schedule on-site training for operators, riggers, and safety professionals.    

We design and manufacture custom-engineered below-the-hook lifting device and overhead cranes, so you can improve safety, streamline operations, and solve your toughest challenges with confidence.
