  • 1x launching trolley 3700, 400 mm with pneumatic tires,
  • 1x trailer coupling

We are happy to offer another axis.


The following components are included:

  • 1 drawbar,
  • 2 supports,
  • 2 pneumatic wheels d = 400mm,
  • Connector

Unfortunately, we do not offer a wheel with ball bearings, as this would have to be made of VA.

Our wheels all have rust-proof plain bearings.

Unfortunately we do not have a photo in the disassembled state. The trailer is partially dismantled approx. 120 x 30 x 30 cm

The track width in the axis is approx. 1100 mm and the wheels are approx. 80 mm wide. The supports also have a lashing strap holder.

Simply thread two lashing straps and the boat lies even better on the trolley.

No, we can only offer PU wheels as 260 PU.

However, the 400s are very high quality (4.00-8 pvc 4ply plain bearings)

That is no problem.

When disassembled, the dimensions are 120 x 30 x 15 cm and the wheels 40 x 40 x 20 cm.

No, unfortunately not. The center distance is approx. 1100 mm.

These are PU foamed wheels as solid material.

No, as these are starting to rust.

The tire is approx. 80 mm wide.

What are the cross-sectional dimensions of the aluminum 4 square tube of the axle? For example 60 x 60 x 3 mm.

For the boat length I recommend the l3700. The use of the large wheels with swivel castors is not a problem.

For this boat length we recommend the L3700.

Shipping to Austria costs 17.99 €.

The wheels are foamed with PU.

The longest tubes are 1100 mm.

The drawbar including the mounted axle is approx. 1200 mm long.

The trolley fits your needs. In the rear area, a tension belt can be pulled through the elongated holes provided for this purpose.

So the boat hangs or lies neatly.

The bow support can be moved lengthways.

For the length of the boat, we recommend the aluminum slip trolley L3700.

The coupling and the handle cannot be used at the same time.

We recommend the slip trolley with tandem axle Alu slip trolley L3700 + tandem axle - boat trolley - dismantled.

Depending on the surface (stony, sandy or gravel), you should also choose the 400 wheels.

If the slip area is level, you can use the 260 tires without any problems.

In terms of dimensions, weight and uneven slip area, we recommend the following combination: aluminum slip trolley L3700 + tandem axle + 400 mm tires.

With gravel and a high boat weight, the small 260 mm wheels are quite problematic (like to dig in).

We recommend the aluminum slip trolley L3700 with wheels d = 400mm. Depending on the subsoil (stony, sandy or gravel), you should use d = 400mm.

The swivel castor is designed for QRO 45. However, if you place lining sheets in between, it will also fit smaller dimensions.

The L3700 is ideal for your boat. Depending on the subsoil (stony, sandy or gravelly), you should use d = 400 mm.

The swivel castor is designed to hold a square tube 45

Since our tires are made with plastic plain bearings (non-rusting), they can be driven at a maximum of 4 km / h according to the manufacturer.

That you have to loosen at least one split pin and bolt to fold the slip wheel is correct (illustration of exploded view & text).


Unfortunately, for reasons of cost, it is not possible to provide or plan for safety chains or the like in this price range.


For a slip wheel construction without lanyards, you would have to spend at least € 35 more (with much smaller wheels). To avoid a possible loss of a bolt or split pin, I suggest folding the wheels on the bank.

We recommend the L3700 aluminum slip trolley for your dinghy.

Depending on the subsoil (stony, sandy or gravelly), you should use d = 400 mm.
