In-House Inspection and Refurbishment
Holloway Houston provides in-house inspection and repair programs designed to keep lifting equipment in safe working shape. Each item sent to our facility is reviewed under controlled lighting and clean conditions, allowing deeper checks than field environments typically allow. Our team examines chains, slings, clamps, load cells, hoists, and lifting components for wear, distortion, missing tags, or surface conditions that indicate the need for repair or removal from use. We identify problems early, help reduce downtime, and provide clear pass/fail decisions according to OSHA and ASME guidance. If an item cannot continue in service, we provide clear notes and replacement paths.
Holloway Houston In-House Testing and Inspection Services
When equipment arrives, it is logged, cleaned when needed, and reviewed visually and with measurement tools. Inspections reference:
Inspections reference :
- OSHA 1910.184 (slings).
- ASME B30.9 (slings).
- ASME B30.10 (hooks, blocks).
- ASME B30.20 (lifting devices).
- ASME B30.21 / B30.16 (lever and chain hoists — manufacturer guidance applies).
- ASME B30.26 (hardware).
If an item passes inspection, a certificate is issued. If it does not pass, the report explains the reason, and the equipment is held for repair or disposal. When a repair is possible and permitted by the manufacturer, the part is restored and then retested. After repair or proof testing, all documentation is updated, and the equipment is returned with proper tagging. Customers routinely send chain slings, wire rope slings, synthetic slings, magnets, shackles, hoists, clamps, hooks, blocks, load cells, and other lifting components. The controlled nature of the in-house environment allows closer inspection, higher accuracy in measurement, and full proof testing using calibrated equipment.
Key In-House Services
Hoist And Component Inspections
Ship hoists to our facility for detailed checks covering frames, gears, hooks, latches, bearings, load chains, and operational functions. Inspections follow ASME B30 guidance, OSHA rules, and manufacturer instructions. Wire ropes, hooks, and link components are reviewed for wear, opening beyond limits, twists, chain stretch, or other surface changes.
Slings And Loose Lifting Equipment Inspections
Send chain slings, wire rope slings, synthetic slings, shackles, hooks, and loose gear for inspection and proof testing. The facility uses calibrated machines to apply controlled loads when needed. Items that can be restored are repaired with matching components allowed by the manufacturer; items that cannot be repaired are removed from use and documented.
Lifting Device Inspections
Material lifting devices are reviewed following ASME B30.20 and manufacturer instructions. Structural parts, connection points, wear surfaces, latch mechanisms, pins, and nameplates are checked. Repairs are applied when allowed, and proof testing can be completed before certification.
Lifting Magnet Inspections
Annual magnet recertification includes function checks and breakaway testing in line with manufacturer instructions and ASME guidance. Magnet faces, handles, locking systems, safety indicators, and nameplates are checked to confirm they meet required performance.
Plate Clamp Repair
Plate clamps are disassembled for internal review. Cams, pins, pads, jaws, springs, and shackle components are examined and replaced when worn. After reassembly, the clamp is proof tested in-house, and full documentation is issued.
Hoist Repair Services
Lever hoists, hand chain hoists, electric hoists, air hoists, and trolleys can be repaired at our facility. Load chains, hooks, gears, bearings, pawls, and brakes are inspected. Repairable units are restored, tested, and returned. Units beyond limits are documented and held for replacement.
Repair & Recertification at Our Facility
Our in-house repair and recertification services are designed to extend the life of your lifting equipment and meet all regulatory standards.
Chain and Sling Repairs
Chains and some sling assemblies may be repaired with matching components approved by the manufacturer. All repaired items undergo verification and proof testing using calibrated equipment. Wire rope and synthetic slings generally cannot be repaired and must be removed from use if damaged
Hoist and Load Cell Repairs
Technicians restore hoists, load cells, and other measuring devices inside our workshop. Frames, hooks, instrumentation, link attachments, and internal parts are checked and corrected when possible. After repair, load-bearing parts are tested to confirm performance.
Welding and Fabrication
Certified welders perform repairs and modifications allowed by the manufacturer. Work includes attachment repair, wear pad replacement, and minor structural corrections that do not change the device’s intended design or rated capacity.
In-House Machining
The in-house machine shop produces custom parts needed for repairs, such as pins, bushings, spacers, and hardware components. Precision machining restores correct fit and alignment for equipment returned to service.
Proof Testing in Our Controlled Facility
At Holloway Houston, proof testing ensures the safety and reliability of your lifting equipment. We subject chains, slings, hoists, load cells, and more to loads beyond their normal limits to verify structural integrity. Our advanced facilities simulate real-world conditions, confirming your equipment can handle regular stresses and is returned safe and dependable.
Rigging Equipment Inspection
Send your rigging equipment to our facility for regular inspections to maintain safety and efficiency. Our team conducts comprehensive evaluations of equipment, including shackles, blocks, elevator links, and spreader bars, identifying wear, corrosion, or any damage that could compromise performance. Through detailed visual and non-destructive testing, we confirm that all rigging equipment meets the required safety standards before it is returned for service.
Load Testing Equipment
Load testing is a crucial service that verifies your lifting equipment can handle its maximum specified loads. At our facility, our load testing services involve applying controlled loads to equipment such as cranes, hoists, and load cells to verify their capacity and performance. This testing helps identify any weaknesses that could lead to failure, providing assurance that your equipment is capable of safely performing when back in operation.
Proof Testing in Our Controlled Facility
Proof testing is completed on a calibrated test bed. Equipment such as chain slings, lifting devices, clamps, hoists, and load cells may be tested after repair or upon request. During testing, the item is loaded to the proof load level specified by ASME B30 standards or the product manufacturer. The load is held and observed while measurements and deflection checks are recorded.
After the test, technicians inspect the item for surface changes, link deformation, throat openings outside limits, stitching failure, or alignment issues. This process confirms that the item can function safely under normal field conditions.
Proof Test Certificate Includes :
- Item ID.
- Test load.
- Technician name.
- Date.
- Machine ID.
- Notes.
Rigging Equipment Inspection
Send shackles, blocks, turnbuckles, spreader bars, elevator links, and similar rigging components to our facility for regular inspection. Technicians check for:
- Wear, surface cracks, and corrosion.
- Pin movement and thread condition.
- Deformation and structural changes.
When needed, non-destructive testing is performed to review internal or hidden changes. Items that pass are tagged; items that fail are held and logged.
Load Testing Equipment
Load testing verifies that equipment such as hoists, load cells, lifting devices, and certain components can sustain their intended working load. Controlled loads are applied using calibrated systems, and the item is observed for any change in shape, alignment, or movement.
Load test records provide clear documentation for compliance and internal tracking.
The Importance of Sending Equipment for Inspection and Repair
Lifting equipment naturally experiences wear over time. Sending items to a controlled facility helps identify issues early and prevents incidents caused by unnoticed damage.
Regular inspection also supports longer service life by catching problems before they progress to failure.
Why Regular In-House Inspections Matter
A structured inspection program in a controlled facility allows closer review than field checks. By examining equipment under proper lighting and using the right tools, issues such as cracks, wear patterns, throat opening changes, and chain stretch can be spotted early. This helps maintain safe operation, minimize interruptions, and keep equipment in working order.
