The Tigrip TZL Load Indicator combines a robust mechanical spring measurement with a clear electronic digital display, providing a reliable load reading without the cost or complexity of a full load-cell crane weigher. Designed for universal lifting and weighing, it suits construction site load verification, in-line crane weighing, sling and chain proof testing, and yard or workshop weighing across 2.5 tonne, 5 tonne, 10 tonne and 20 tonne capacities. Manufactured by Columbus McKinnon under the Tigrip brand, supplied with test certificate and operating manual, with shackle and hook adapter kits available separately.
Key Features
- Mechanical measurement, digital display — robust mechanical spring measurement combined with a high-contrast electronic readout
- Universal application — use as a stand-alone load indicator or in-line below a crane hook
- Lightweight construction — from just 1.7 kg net weight at the 2.5 tonne capacity, contributing little to lift residual capacity
- No external power required — battery-powered display, no mains supply needed on site
- Robust steel housing — built for daily site and workshop use
- Four capacity options — 2.5 tonne, 5 tonne, 10 tonne, and 20 tonne models cover the most common lifting and proof-testing applications
- Adapter kit compatible — designed to accept matching Tigrip shackle or hook adapter kits, available separately

More About This Product
The Tigrip TZL Load Indicator combines a robust mechanical spring measurement with a clear electronic digital display, providing a reliable load reading without the cost or complexity of a full load-cell crane weigher. Designed for universal lifting and weighing applications, the TZL is well-suited to general construction site load verification, in-line crane weighing, sling and chain proof testing, and yard or workshop weighing. Capacities cover 2.5 tonne, 5 tonne, 10 tonne, and 20 tonne lifting applications. Manufactured by Columbus McKinnon under the Tigrip lifting brand, the TZL is supplied complete with a manufacturer's test certificate and operating manual. Shackle and hook adapter kits sized to match each capacity are available separately.
Suitable Applications
The TZL is suited to construction site load verification, scrap and recycling weighing, plant and equipment verification, sling and chain proof testing, and any universal lifting application from 2.5 to 20 tonne where a simple and reliable load indicator is required. Where higher accuracy or full crane-weigher functionality is needed, the Yale TKL, TKR, TKE, or TKI ranges should be specified instead.
How to Use the TZL Load Indicator
- Inspect the load indicator and adapter kit visually for damage before each use.
- Fit the appropriate shackle or hook adapter kit (sold separately) to the top and bottom of the load indicator if required.
- Attach the load indicator in-line between the crane hook and the load, ensuring all connections are fully tightened and secured.
- Switch on the electronic display.
- Allow the display to stabilise and zero the reading if required.
- Lift the load smoothly and allow the reading to stabilise before recording the weight value.
- Switch off the display after use to preserve battery life.
Warning:
Do not exceed the rated capacity of the load indicator or its adapter kits. Do not shock-load the unit. Do not use the load indicator if the display shows an error or if the housing shows signs of damage. The crane operator must remain in full control of the lift at all times — the load indicator does not replace standard rigging and lifting procedures.
Safety Information
- Ensure the operator is fully familiar with the load indicator's operation and the supplied operating manual before use.
- Verify that both the crane or hoist and the load indicator are rated for the intended load.
- Inspect the load indicator, adapter kit, pins, and shackles visually before each use.
- Ensure all connection pins are fully tightened and secured before applying load.
- Do not exceed the rated working load of the load indicator or its adapter kits under any circumstances.
- Do not shock-load the load indicator — apply load smoothly and progressively.
- Do not modify or attempt to repair the load indicator; return to an authorised service centre for any service work.
Inspection and Maintenance
Inspect the load indicator and adapter kit visually before each use, paying particular attention to the housing, connection points, pins, and the electronic display for damage or moisture ingress. Keep the unit clean and dry between uses. The TZL is supplied with a manufacturer's test certificate; LOLER 1998 thorough examinations are required every 12 months by a competent person. Recalibration is recommended at the same interval to maintain load reading accuracy.
Frequently Asked Questions
Q: How is the TZL different from a crane weigher like the TKL?
The TZL is a load indicator with a mechanical spring measurement and electronic display. Crane weighers like the TKL use electronic load cells and offer higher precision. Use the TZL for general load verification, and a crane weigher when documented weighing accuracy is required.
Q: What attachments are required to use the TZL?
Shackle and hook adapter kits matched to the load indicator capacity are available separately. See the Tigrip Shackle Adapter Kit and Hook Adapter Kit product listings for the correct kit for your TZL model.
Q: Can the TZL be used in-line on a crane hook?
Yes. The TZL is designed for in-line use between a crane hook and the load, as well as for stand-alone hand-held checks.
Q: Is calibration certification included?
A manufacturer's test certificate is supplied as standard. Additional calibration certification is available on request.
Q: How often should the TZL be inspected and recalibrated?
Visual inspection should be carried out before each use. LOLER 1998 thorough examinations are required every 12 months. Recalibration is recommended at the same annual interval.
Q: Does the TZL need a mains power supply?
No. The electronic display is battery-powered, so the TZL can be used anywhere on site without access to mains power.
Q: Can the TZL be used outdoors?
Yes. The TZL is built for site and workshop use including outdoor environments. Avoid prolonged exposure to standing water.
