LTP 61 Shut-off Nutrunner Not only accurate, but also very fast

2

Some joints are more critical than others. If you need

a higher level of accuracy in your work, take a look at

Atlas Copco’s shut-off nutrunners.

They have become standard pieces of equipment

at truck manufacturers such as Scania and Volvo.

And are becoming more and more common in

service workshops. Why?

How important is accurate tightening for your customers?

The same torque time after time

A shut-off nutrunner is a reliable tool. You decide what torque you want – anything from 60 - 4 000 Nm depending on the model – and that’s what you get. No more, no less. Even in soft joints. And as the name suggests, it shuts off at the torque you have selected. So you get the same accu-rate result time after time – regardless of the opera-tor and their level of experience. A clear shut-off signal tells operators when the tightening cycle is fi nished. Not only does this

ensure high accuracy, but it also boosts productivity because the operator can immediately move on to the next bolt without having to spend time checking to see if the bolt needs tightening a little more.

First the bad news

A shut-off nutrunner gives you reliable tightening because of the way it builds up torque in a smooth, controlled and continuous way. This produces excellent quality in the tightening phase. However, with a standard shut-off nutrunner,

ge

this controlled action slows things down during the rundown phase.

Now for the good news

Ever changed a wheel? First you spin the wrench, then tighten slowly with both hands. Two-speed tightening. That’s what you get with the LTP 61 – the market’s only nutrunner with two motors. One for rundown. One for tightening. If you want to know how this can boost productivity, turn the page.

4

Ten times faster rundown

A conventional, mid-size, shut-off nutrunner works at around 20 rpm, during both rundown and tightening. A mid-range LTP 61 runs down at 210 rpm – that’s 10 times faster. If you have a large number of nuts to tighten, the LTP 61 will save you a considerable amount of time, boosting the productivity of your company. Chances are, it will pay for itself within months.

How important is productivity for your company?

With the LTP 61, you don’t have to compromise: you

get highly accurate tightening and high productivity.

The secret is two motors. One high speed motor for

fast rundown. And one high torque motor for reliable

tightening.

The fastest tool on the market just got faster

Twin motors might sound simple. But you won’t fi nd another nutrunner like the LTP 61 on the market. Its predecessor, the LTP 51, has been winning over fans for over twenty years. In some indus-tries, such as truck and bus manufacturing, it has become an accepted standard.

5

The new LTP 61 is as accurate as its predeces-sor, but it is faster. Twice as fast in rundown. And yet the new range is only marginally heav-ier than the existing one. When we say that Atlas Copco stands for “innovation, commitment and interaction” we really mean it.

Run-down speed is up to ten times higher compared with a single-motor nutrunner.

How important is ergonomics at your workplace?

Shut-off nutrunners are quite in operations and vibration

levels are low. Operators who progress from impact

wrenches really appreciate the difference.

Very quiet

But how quiet is the LTP 61? A shut-off nutrunner builds up torque continuously, without interruption. In other words, there is no noise generated by the actual process. Sound levels are also kept low because all exhaust air is piped through the handle into a hose, minimizing noise from the pneumatic system.

Low vibration levels

The LTP 61 has low vibration level because torque is

transferred continuously. Compare this to an impact wrench in which torque is produced by a rotating metal hammer slamming into the output shaft.

Minimize strain on wrists and arms

Wrist and arm strain is kept to a minimum with shut-off nutrunners because the reaction force is handled by a torque-reaction bar. Our unique, innovative reac-tion bars are easy to use to keep productivity levels high.

Single-handed operation

The LTP 61 is light, compact and well-balanced and so can be used with just one hand. The rubber pistol grip has been ergonomically optimized for maximum operator comfort.

Increasing output at Volvo Trucks

“With output being ramped up every year, productivity is getting more and more important,” says Dennis Johansson, Process Engineer at Volvo Trucks in southern Sweden. Volvo Trucks is already using more than 200 LTP 51 shut-off nutrunners on axle and chassis assembly lines. “The Atlas Copco machines are reliable and they give us the accurate torque that we need,” says Dennis.

Perfect for long run-downs

Producing over 26,000 units every year, the need to shave off a few seconds here, a few seconds there is a pressing matter. “The LTP 61 is that much faster, ”says Dennis, “so it’s perfect for long run-downs. We expect to see more LTP 61s turning up on the production lines in the near future.”

How many tools do you really need in your workshop?

A shut-off nutrunner is a sophisticated tool. But for

many workshops it has not been economically viable

to own an advanced wrench that performs just one

dedicated task. However, with three simple accessories,

you can use one LTP 61 for dozens of different jobs.

And that means a sophisticated tool has now become

a very economical one too.

Multi-Torque Selector

Transform one nutrunner into four: the Multi-Torque Selector allows you to preset four different torque levels per tool. Order ready-mounted or as an acces-sory to existing LTP 51 and 61 nutrunners.

Multi-Point Reaction Bar

In many workshops, an application that requires a different torque also requires a different reaction point. The Multi-Point Reaction Bar features a sliding

bracket that gives you a number of different reaction points.

S-Bar – straight out of the box

A blank reaction bar has to be bent, cut or welded – an extra “to do”. The geometry of the S-Bar has been optimized to provide a maximum number of reaction points. This means you’ll be able to use the S-Bar in about 70-80 percent of all applications straight out of the box.

From 60-4 000 Nm

With a range consisting of 11 different tool sizes, there is an LTP 61 to suit all kinds of applications. The smallest model weighs just 2.6 kg and delivers 60 Nm, while the largest version supplies 4 000 Nm.

LTP 61 – accurate, fast and ergonomic

Increase tightening accuracyWith automatic shut-off you get a high level of tightening precision, even in soft joints. This helps increase productivity since the operator gets a clear shut-off signal when tightening is completed.

Boost productivityUnique twin-motor drive: one for high speed rundown, the other for high precision tightening.

Single-handed operationBecause the LTP 61 is light, compact and well-balanced, it can be used with just one hand.

Now easier to run in reverseUnlike its predecessor, the LTP 61 runs in reverse and stays in reverse until you change the setting. Thanks to a new mode selection, you can now hold the tool with just one hand, whatever direction you run the machine.

Twice as fast as the LTP 51Thanks to the new motors, the rundown speed has been doubled in comparison with its predecessor.

Virtually silent and vibration-freeShut-off nutrunners generate no process noise. And by building up torque continuously, they are much quieter than impact wrenches.
