NEVER LOSE A WHEELThe QuestionWhat use is a truck or bus withmissing wheels?You probably hope that your vehicleswill never lose their wheels or maybeyou think that it’s impossible for thisto happen to you.

Despite these thoughts, every year thereare numerous of wheel loss incidents in the

UK, – that’s the wheel coming off completely.There are many other incidents of lost wheel nutswhich fortunately are noticed before the wheelbecomes detached.

How can you make sure this doesn’thappen to you? What if it did?

Consider the impact of a losing wheel duringyour busy day. Late deliveries, damage to vehicles

and freight, injury or even death to drivers or passers by.What if you carried passengers? Imagine a bus load of peoplestranded or detained waiting for a relief vehicle and missingimportant appointments. It doesn’t bear thinking about.

What could happen to your operator licence?What about you? What could happen to yourjob? Worse still, could you be held responsiblefor someone else’s negligence?

There are lots of questions here, but there isan answer...

The AnswerFitting Prolock wheel security locks offers the completesolution and peace of mind to all vehicle operators andfleet engineers.

� Prolock wheel nut clamps fit over 2 adjacent wheelnuts, providing a physical, solid lock against anynut movement.

� Prolock clamps grip against the flats of the wheel nut,not just the points.

� Independent tests by major UK fleet operators find thatProlock clamps require 3 times the amount of force tomove the wheel nut than other wheel loss deterrents.

� Prolock clamps can retain a wheel even if the wheelnuts have lost torque through temperature change orwheel corrosion.

� Prolock is TÜV approved and has a 20 year track record.

� Prolock clamps are made from specially coated steel,therefore they do not melt or distort.

� Prolock clamps are ideal for use under stainless steelwheel trims.

� Prolock clamps are easy to fit and remove.

� Prolock clamps are made in different sizes to fit mostcommercial vehicles.

How do I fit Prolock Clamps?

1 Fit wheel to vehicle using best practice policy, ensuring all wheel nuts are correctlytorqued, and that time has been allowed for settlement etc.

2 Prolock clamps are fitted to the wheel nuts using a specially designed tool which hasa magnetic clamp holder to help locate the clamp correctly over the pair of wheelnuts you wish to lock.

3 Once the Prolock clamp is in position, it can be driven onto the nuts using a soft faceheavy hammer. We recommend the Prolock nylon faced dead blow hammer with alead shot filling. This gives a solid impact, making fitting easy and efficient. Ordinarysteel lump hammers may damage the fitting tool and are noisy and hard work.

4 The Prolock fitting tool is designed with a depth stop shoulder which stops the Prolockclamps from being hammered on too far. Once the stop is reached, the lock is fitted.

5 Check that the Prolock Clamp is fitted completely onto both nuts and is tight with nomovement detectable.

6 We recommend fitting 3 Prolock clamps to each 10 stud wheel, and at least 2 to a 6or 8 stud wheel. Whilst locking all wheel nuts is a temping option, having unlockednuts leaves the facility to enable regular torque checks.

7 Prolock clamps are removed, either by simply undoing the nut with a wrench, or byusing a small pry bar to lever the clamp off. We do not recommend that any clamp isrefitted after it has been removed. The security of any Prolock clamp can only beguaranteed for single use.

Correct fitting.

Propoint wheel nut safety markers are widely used as an early warning of wheel nut movement. Propoint markers are especiallydesigned for use with the Prolock wheel nut clamps. By fitting these to adjacent unlocked nuts these give warning of torque losson the locked wheel. Although a locked wheel may still be attached, it may be necessary to periodically check torque.
