Description
Coal-fired power plants at Vinh Tan, Duyen Hai and Quang Ninh unload ships at their own jetties. Grab unloaders lift coal from the holds, and stacker-reclaimers build and dig the stockpiles. Those machines ride on large travel gear and booms that take heavy shocks. The Snap-on TE1503FUC torque wrench helps maintenance crews check the big bolts with a two-needle dial.
Coal yard bolts and the Snap-on TE1503FUC torque wrench
- Grab unloader trolley, hoist base and boom hinge bolts.
- Stacker-reclaimer bucket wheel and boom conveyor frame bolts.
- Travel gear and rail clamp bolts on yard machines.
- Hopper and chute frame bolts where the builder lists an ft-lb value.
Slewing ring bolts often call for hydraulic tensioners, and builders set every value. So follow the manual first. Then use the TE1503FUC only where a target sits inside its 1,500 ft-lb dial.
Peak reading after a hard pull
Yard machines stand in the open, so wind and coal dust make a dial hard to watch during a pull. On the TE1503FUC, one needle marks the targeted torque, while the second stays at the value reached. Thus the fitter can finish the pull, steady the wrench, and then read the result. As a result, the logbook gets a real number rather than a guess.

Snap-on prints this row in the US Reading/Standard 2% Accuracy table of CAT1500i. According to that page, certificate of calibration models add a C suffix to the stock number. So the TE1503FUC is the certificate form of the TE1503FU. Since Lost in HCM’s title adds with Chart, confirm the paperwork when you order.
Start of the 2% band
Lost in HCM lists the wrench under US Reading/Standard 2% Accuracy. In Snap-on’s terms, that means within 2% of reading from 20% of full scale through full scale. Hence the band on the TE1503FUC starts at 300 ft-lb. In metric terms, 1,500 ft-lb is roughly 2,034 N·m.
Handling an 80 inch dial on a yard machine
A TE1503FUC with its 5 foot handle needs a clear path and a helper. First, brace your feet and keep the head square on the nut. Next, pull in one slow motion while your partner holds the head. Snap-on warns against loosening bolts with a Torqometer, so free seized nuts with a breaker bar. Afterward, blow off the coal dust and store the wrench indoors, within Snap-on’s 0 to 100 °F range.

Bulk handling FAQ for the TE1503FUC
Does Snap-on make a lamp model at this size?
Yes, Snap-on lists the TE1503L in the same table. It uses a flashing lamp rather than the follow-up needle.
Will coal dust harm the dial?
Dust and grit can wear any dial wrench. Wipe it after use and keep it in a closed cabinet.
Is the TE1503FUC a one-person tool?
With the extension handle fitted, two people work more safely. One pulls while the other steadies the head.
