Snap-on ATP16000 Torque Multiplier, Digital, 16,000 ft-lb, 2-1/4″ Male Hex Output, 625:1 Ratio

Description

Propeller shaft couplings, mill housings and shovel slew rings use bolts that no hand wrench can finish. The Snap-on ATP16000 torque multiplier reaches 16,000 ft-lb, yet the operator still drives it with a ratchet. It is the top size in the Snap-on ATP digital table. That size brings planning questions as well, from lifting to sockets.

Plan the lift before the pull

Snap-on lists the ATP16000 at 85 lb, with a 12.5 inch outside diameter and a 10 inch height. So treat it like a small lifted load, not a hand tool. Use a hoist, a chain block or a fixture to bring it onto the joint. Then support its weight while the reaction takes up, because a hanging tool side-loads the bolt and the output hex.

Figures for the Snap-on ATP16000 torque multiplier

• Output capacity of 16,000 ft-lb, about 21,700 N·m.
• Input capacity of 26 ft-lb through a 1/2 inch female square.
• Gear ratio of 625:1.
• Output drive: 2-1/4 inch male hex.
• Height 10 inches, diameter 12.5 inches, weight 85 lb.
• Output accuracy of plus or minus 1%, per the catalog.

The included controller shows peak or track readings and sounds an over-torque alarm. In addition, it has a printer interface for joint records.

Matching the 2-1/4 inch hex output

A male hex output does not take a normal square-drive socket. Instead, it pairs with hex-drive sockets or a drive adapter. Snap-on mentions a wide choice of optional adapters and mounting fixtures for this range. Therefore list your nut sizes when you ask for a price, and Lost in HCM can propose the matching set.

Patience at 625:1

High ratio means low effort, since the operator applies only about 26 ft-lb at full output. However, the nut turns very slowly. Run the joint down with other tools first. Then let the Snap-on ATP16000 torque multiplier do the final pull, while the display shows the torque build.

Heavy industry jobs

Shipyards in the north and center can put this class of tool to work on shaft couplings and rudder stocks. Meanwhile, steel and cement plants bring it out for mill housings, kiln drives and crusher frames. Mining crews also apply it to slew rings and large track joints during rebuilds.

Safety and storage for the Snap-on ATP16000 torque multiplier

Keep people out of the reaction path and wear eye protection. Stay within the rated torque, and do not use the tool to break seized fasteners loose, as Snap-on warns. Afterward, clean the hex and base pins, then store the unit on a pallet or in its case. Plan periodic recalibration with an accredited lab of your choice.

Quoting a 16,000 ft-lb setup

SMK Vietnam presents this tool for its partner Lost in HCM, which supplies it and confirms the configuration. Please request a quote from Lost in HCM with your nut sizes, target torques and site. You can also review smaller torque multipliers, check Snap-on for maker details, or contact SMK Vietnam.

Questions from heavy bolting crews

Can one person handle the ATP16000?

Not safely by hand alone. At 85 lb, it needs a hoist, a fixture or a second person to position it.

Is there a torque-angle version of the ATP16000?

Yes. Snap-on lists the angle measurement model separately as the ATP16000E, so this code covers torque only.

What do we send with a quote request?

Send nut sizes, target torques, joint photos and the site address. That helps Lost in HCM match adapters and reaction tooling.
