Yale TKL Compact Crane Weigher

Model TKL | Compact Digital Weigher | Direct Readout | 1t to 3.2t Capacity | From 3kg Net Weight | CMCO Group Manufacture

The Yale TKL Compact Crane Weigher is a lightweight digital crane scale for everyday in-line weighing on cranes, lifting beams and overhead hoists, in 1 tonne, 2 tonne and 3.2 tonne capacities. From just 3 kg net weight it is the lightest weigher in the Yale range, with a compact body that minimises headroom loss and an integral digital display reading directly in kilograms. Manufactured by Columbus McKinnon under the Yale brand, supplied with test certificate and manual, for use with grade 8 forged shackles or hooks.

Key Features

• Lightweight construction — from just 3 kg net weight, minimising headroom loss and contributing little to lift residual capacity
• Direct digital readout — high-contrast display visible from ground level, no remote control required
• Three capacity options — 1 tonne, 2 tonne, and 3.2 tonne models cover the most common day-to-day construction lifts
• Grade 8 attachment compatible — designed for use with grade 8 forged shackles or hooks
• Robust steel construction — built for daily site use, suitable for outdoor and indoor environments
• Tare and zero functions — tare empty containers and zero the display between lifts
• Long-life battery — extended battery life suitable for full working days, battery replacement straightforward

Technical Specifications

TKL models feature a high-contrast digital display with direct on-unit readout. For remote-controlled weighing in the same compact form factor, see the Yale TKR or the Yale TKE and TKI ranges.

More About This Product

The Yale TKL Compact Crane Weigher is a lightweight digital crane scale built for everyday in-line weighing on cranes, lifting beams, and overhead hoists at capacities up to 3.2 tonne. The compact body keeps headroom loss minimal during lifts, and the integral digital display gives a direct readout in kilograms without the need for a remote control. From just 3 kg net weight, the TKL is the lightest weigher in the Yale range, making it ideal for sites where the weigher itself contributes to the lift residual capacity. Three capacity options cover 1 tonne, 2 tonne, and 3.2 tonne lifting applications. Manufactured by Columbus McKinnon under the Yale lifting brand, the TKL is supplied complete with a manufacturer's test certificate and operating manual. Use with grade 8 forged shackles or hooks as the lifting attachment.

Suitable Applications

The TKL is suited to everyday construction site weighing, plant and equipment verification, scrap weighing, in-house manufacturing lifts up to 3.2 tonne, and as an entry-level weigher for sites that do not require remote control operation. Particularly well-suited to low-headroom lifts where a heavier weigher would consume too much of the available residual capacity.

How to Use the TKL Crane Weigher

1. Inspect the weigher visually for damage before each use.
2. Attach the top shackle to the crane hook or lifting beam, ensuring the shackle pin is fully tightened and secured.
3. Attach the bottom shackle or hook to the load, ensuring the rated capacity of the attachment matches or exceeds the load weight.
4. Switch on the weigher using the power button on the display unit.
5. Allow the display to stabilise and zero the reading if required.
6. If weighing the contents of a container, attach the empty container, then press the tare button to zero the displayed weight.
7. Lift the load smoothly and allow the reading to stabilise before recording the weight value.
8. Switch off the weigher after use to preserve battery life.

Warning:
Do not exceed the rated capacity of the weigher or its attachments. Do not shock-load the unit. Do not use the weigher if the display shows an error code or if the housing shows signs of damage. The crane operator must remain in full control of the lift at all times — the weigher does not replace standard rigging and lifting procedures.

Safety Information

• Ensure the operator is fully familiar with the weigher's operation and the supplied operating manual before use.
• Verify that both the crane or hoist and the weigher are rated for the intended load.
• Inspect the shackles, pins, and weigher housing visually before each use.
• Ensure shackle pins are fully tightened and secured before applying load.
• Do not exceed the rated working load of the weigher or its attachments under any circumstances.
• Do not shock-load the weigher — apply load smoothly and progressively.
• Do not modify or attempt to repair the weigher; return to an authorised service centre for any service work.

Inspection and Maintenance

Inspect the weigher visually before each use, paying particular attention to the housing, shackles, shackle pins, and the display for damage or moisture ingress. Keep the unit clean and dry between uses. The TKL is supplied with a manufacturer's test certificate; LOLER 1998 thorough examinations are required every 12 months by a competent person, and recalibration is recommended annually to maintain stated weighing accuracy. UKAS-traceable calibration can be carried out by Columbus McKinnon or any approved weighing equipment calibration laboratory.
