Yale TKR Crane Weigher with Remote Control

Model TKR | Wireless Remote Control | Digital Display | 5t to 12t Capacity | Grade 8 Attachment Ready | CMCO Group Manufacture

The Yale TKR Crane Weigher is the remote-controlled, mid-capacity sister to the TKL, designed for in-line weighing on cranes, lifting beams and overhead hoists from 5 tonne up to 12 tonne. A wireless remote control lets the operator read and tare loads from ground level, while the compact body retains the direct on-unit display for redundancy. Manufactured by Columbus McKinnon under the Yale brand and supplied with test certificate, remote control, batteries and operating manual.

Key Features

• Wireless remote control — tare and read loads from ground level or a remote operating position, no need to access the display directly
• Capacities to 12 tonne — covers the mid-capacity construction and industrial weighing range, larger than the TKL
• Direct digital readout — high-contrast display available locally on the unit as well as via the remote, providing redundancy
• 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, controllable from the remote
• Three capacity options — 5 tonne, 8 tonne, and 12 tonne models cover the mid-capacity construction range

Technical Specifications

Note: the Columbus McKinnon internal model designations "TKR 2,0" and "TKR 3,2" refer to the 8 tonne and 12 tonne models respectively — the numerical suffix is an internal product code, not the capacity rating. Always confirm capacity by the kilogram figure rather than the model suffix.

More About This Product

The Yale TKR Crane Weigher is the remote-controlled, mid-capacity sister to the TKL. Designed for in-line weighing on cranes, lifting beams, and overhead hoists at capacities from 5 tonne up to 12 tonne, the TKR ships with a wireless remote control so the operator can read and tare loads from ground level or from a remote operating position. The same compact body and direct on-unit display as the TKL is retained for redundancy, with the remote providing operational convenience. Three capacity options cover 5 tonne, 8 tonne, and 12 tonne lifting applications. Manufactured by Columbus McKinnon under the Yale lifting brand, the TKR is supplied complete with a manufacturer's test certificate, wireless remote control unit, batteries, and operating manual. Use with grade 8 forged shackles or hooks as the lifting attachment.

Suitable Applications

The TKR is suited to mid-capacity construction lifts, formwork and steel section weighing, precast concrete element weighing, plant verification, and any in-line crane weighing application from 5 tonne to 12 tonne where remote operation is required. Particularly well-suited to lifts where the operator is positioned away from the load, or where viewing the on-unit display from ground level is impractical.

How to Use the TKR Crane Weigher

1. Inspect the weigher and remote control visually for damage before each use.
2. Fit fresh batteries to the remote control if required.
3. Attach the top shackle to the crane hook or lifting beam, ensuring the shackle pin is fully tightened and secured.
4. Attach the bottom shackle or hook to the load, ensuring the rated capacity of the attachment matches or exceeds the load weight.
5. Switch on the weigher using the power button on the display unit or the remote control.
6. Allow the display to stabilise and zero the reading if required.
7. If weighing the contents of a container, attach the empty container, then press the tare button on the remote or display to zero the displayed weight.
8. Lift the load smoothly and allow the reading to stabilise before recording the weight value.
9. 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, weigher housing, and remote control 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.
• Keep the remote control in a safe location when not in use to prevent damage or accidental operation.

Inspection and Maintenance

Inspect the weigher, attachments, and remote control visually before each use, paying particular attention to the housing, shackles, shackle pins, display, and remote casing for damage or moisture ingress. Keep the unit clean and dry between uses, and store the remote control in a safe location. The TKR 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.
