OTHER LEVELLING OPTIONS
Locknlevel
Locknlevel is a popular airbag device, which allows you to elevate your caravan wheels, together or independently, with the minimum amount of hassle.
Its tough nylon-reinforced polypropylene bags weigh in at 4kg in single-wheel format and 7kg for twin-axles.
To use one, you simply place it on the ground in front of, or behind, your caravan wheel and manoeuvre the wheel into the centre of the deflated airbag.
Then you pump it up. We recommend using a compact electric car-tyre pump.
Locknlevel can raise a caravan up to 15cm (6in), depending on its weight, and has a maximum 30psi (2 bar) pressure rating. Here’s how to use it:
1 On gravelly pitches, where a sharp stone could puncture the Locknlevel, consider placing a length of board (cut to size) underneath your airbag.
2 Note where the wheels will be when your tourer’s in the ideal position on your pitch. Now manoeuvre the caravan to just in front of, or behind, that point.
3 Place your Locknlevel in the ideal position, in front of or behind the caravan wheel(s), with the valve system facing outwards, so it is accessible.
4 Now, either towing or using your motor mover, slowly manoeuvre your tourer onto the deflated Locknlevel.
5 Ensure that the caravan wheels are between the yellow lines, and the two yellow dash lines align with the hub centre of the front or rear wheel (depending which side you’re raising).
6 Apply the caravan handbrake, and chock the wheels that aren’t being raised at this point.
7 Fix your car tyre pump to the Locknlevel inflation valve.
8 If you simply want to raise one side of the caravan to achieve a level stance, with a twin-axle van, turn the Locknlevel valves so that both of the airbags inflate at once.
9 If you want to raise just one wheel on your twin-axle van, for example to fit an Al-ko wheel lock, you’ll need to turn the isolator switch on the valve system to the appropriate position, to inflate one of the airbags.
10 Turn on your pump to inflate the Locknlevel. To pump up one airbag takes three to five minutes, depending on your pump. To inflate a double airbag, allow seven to 10 minutes.
11 Check the spirit level as the bag inflates, and stop pumping when the caravan achieves a flat stance.
12 Remove the pump. Your caravan should now be level, although you can tweak the height by adding more air or letting some out. If, over a period of time, you think that the caravan has sunk, simply top up the airbags.
13 To deflate the Locknlevel, you just need to open the valve. You can now tow your caravan off the airbags.
There are several other benefits of using Locknlevel. The airbag system allows you to raise the caravan when you can’t reach
