Description
Airports such as Tan Son Nhat, Noi Bai and the new Long Thanh terminal dock aircraft at passenger boarding bridges. Each bridge drives on wheels, swings on a rotunda and lifts on columns, often dozens of times a day. Ground equipment teams service them overnight between flights. The Snap-on TEX602TLA Torqometer helps them tighten heavy bridge bolts, and a lamp flashes when each pull hits its target.
Boarding bridge work with the Snap-on TEX602TLA Torqometer
- Wheel bogie and drive motor mounting bolts.
- Lift column and carriage bracket bolts.
- Rotunda column base and support frame bolts.
- Cab rotation and canopy frame fixings within range.
Still, every value comes from the bridge maker’s maintenance manual. So check the manual and the joint method before each job, and keep the TEX602TLA for joints that list a torque.
Snap-on data for the TEX602TLA
| Item | TEX602TLA (CAT1500i p.335) |
|---|---|
| Input / output drive | 3/4 in female / 3/4 in male |
| U.S. range | 600 ft-lb |
| Increments | 10 ft-lb |
| Length / width / head depth | 9 in / 3-1/4 in / 3-3/4 in |
| T bar | Not included; 81TQP optional |
| Follow-up twin | TEX602TFUA |
These numbers come from the US Reading T-handle table in catalog CAT1500i. The table flags this size with a note that the T bar is not included. It also says a C on the stock number orders a certificate of calibration. Because this code lacks the C, plan your own check on arrival.
A night shift lamp
Ramp work at night means floodlights, jet noise and tight time slots. As a result, a technician under the bridge may not see a dial clearly. The TEX602TLA flashes its built-in light once the targeted torque arrives. Then the technician stops pulling, and the next bolt follows without delay.
Where the Snap-on TEX602TLA Torqometer reads best
Lost in HCM lists this head under US Reading/Standard 2% Accuracy, and it also tags the head for hydroelectricity. Snap-on defines Standard as within 2% of reading from 20% of full scale upward. On this dial, that span runs from 120 ft-lb to 600 ft-lb, or about 813 N·m. For larger column bolts, the TEX1003TLA reaches 1,000 ft-lb with a 1 inch output.
Ramp-side care
Jet fuel, hydraulic oil and rain all reach tools on an apron. Therefore wipe the Snap-on TEX602TLA Torqometer after each shift, and store it in the workshop rather than on the bridge. Also keep the head square to the bolt during the pull. Never use it to free a seized bolt, and send it for periodic recalibration.

Ground equipment FAQ
Does the TEX602TLA include a T bar?
No. The catalog marks this size with a note that the T bar is not included. It names the 81TQP as the optional handle, so add it to the quote.
What is 600 ft-lb in N·m?
About 813 N·m. The TEX602TLA reads ft-lb only, so convert any metric spec before you set the target.
Why choose the TEX602TLA over the follow-up model?
The lamp helps when you cannot watch the dial, such as under a bridge cab. If you need a held peak for the record, the TEX602TFUA suits better.
