SpeedMobileStage designs and builds its mobile stages to work for many years.

But in the future you may need our help.

That’s why we have a well-stocked spare parts in our warehouse. 90% of  parts to our mobile stages have at our place, which significantly shortens the time of delivery. For your convenience, we have created PARTS CATALOG of our stages. Catalogues are for download in the section „Questions and Answers” below.

We provide service and inspection by the „PROTECT SERVICE”. The program is a series of periodic, voluntary control tests of your stage. The service program is designed to determine the overall security level of mobile stage. More about the program below.


OPERATION – Questions and Answers

The „PROTECT SERVICE” program is a series of periodic, non-mandatory control tests of your stage. The service program is designed to determine the overall security level of mobile stage, the frame, chassis, structure, surface, and sheathing – eg. The effects of wear, bad weather or corrosion, and any changes in the level of safety resulting from repairs or replaced components.Special attention is paid to the running gears, braking systems, suspension, frame construction, screw connections (screws, bolts, bearings), power hydraulics and generally inside the device. Test inspections are voluntary and should be performed every 12 months with the first review performed after the first 24 months of use. Inspections are documented and performed by the manufacturer. Detailed conditions and research program control can be downloaded in tab MOBILE STAGE / tab. SERVICE.



At your disposal we have a professional CATALOGUE OF PARTS based on our experience, which includes consumable parts and secondary – complemented by technical descriptions, photos, drawings, diagrams and graphical applications in our stages. With the catalogue of parts, without any problems, you can individually select the required part or check its appearance or specifications. Information about the replacement parts listed in the catalogue are always up to date. Our catalogue is very simple and intuitive. It offers a wide range of data needed to properly identify the correct replacement part.

Storage of mobile stage is simple and trouble-free procedure. It is allowed to store the trailer directly „under the sky” – outdoor, but we recommend in case of long period of parking (eg. Winter period) when not in use, to keep it under cover. Our experience shows that this significantly increases the service life of the stage. In the case of  absence of roofing for the stage, we suggest to protect the trailer with cover, which is available in our offer.



Every vehicle roadworthy on public roads subject to mandatory periodic technical inspection – MOT at the diagnostic station.

Our trailers must be tested at vehicle inspection station. The first technical inspection – MOT is carried out  3 years from the initial registration, each succeeding every year. . Technical inspection will cost up to 50 euros.



What is the correct tyre pressure? The easiest way to find out, it’s the tyre itself. Take it into the hands, or lean to it (if fitted) and read values on the side of the tyre. At the photo we are looking at tire size 185R14C dedicated to most of our trailers. At it’s side (the place is quite random, but if you pay attention to the side of tire, you can find it) we can see the following message: „MAX PRESSURE: 450 kPa”. That’s your maximum allowable pressure for the tires (in kilopascals). If this is a dedicated tyre for your trailer, it will be the correct pressure.

20150619_095126If you move the decimal point 2 places to the left, you get a score of 3.0. This value corresponds to the same pressure expressed in bars. So manometer (pressure gauge) can show no more than 3.0 bar.

Is a popular effect for trailers with overrun brakes. The reason is usually always the same – the brake system needs to be adjusted. This problem should not be ignored because it means that braking performance of the trailer can be significantly reduced. Adjusting trailer brakes is described in a separate topic.


The reason is usually the same: poorly adjusted or disregulated overrun brake. This means that the brake pads do not sufficiently move away from the walls of the brake drum.


The reason is always the same – crooked axle arm of the trailer. Damaging the axle arm of the trailer is not easy. It may be caused from the crash  – hitting the wheel at high speed to an obstacle (eg. The curb), which also may cause damage to a tire and curvature of the rim. After changing the wheel, defect can be unnoticed but reveals itself while driving and tire checks. The remedy is to exchange axle arm or the entire axis.




To adjust the brakes you need to spread out drums, evaluate their wear, replace the defective parts but above all you have to grease the mechanism and do regulation of clearance. This applies to trailers with known mileage or age.

Next thing to do is raise the trailer to a point when wheels rotate and adjust the spacing of the jaws from the drum (depending on the manufacturer toothed ring inside or the adjustment screw on the side of the chassis). At the beginning dismantle adjustable jaws to lock the wheel then loosen until the wheel starts to turn freely, however, friction of jaws and the drum should be slightly audible. We do the same with the other side. NOTE. When doing regulation revolve the wheel forward in the direction of travel.Then we adjust the potential difference in the braking force of the wheels. The easiest way: wheels in the air, apply the parking brake slightly and check that the wheels rotate with equal resistance. If you still need regulation pull up the screws slightly on the of the weaker side or loosen on the stronger. This treatment is not always necessary because Knott implemented as a standard brake with automatic adjustment ANS.


Then we pull up links by pulling rod not to have a large clearance (initially) on a drawbar connecting links of the pull rod. Please check after the regulation that the wheels are rotating freely, if not, then it’s been pulled too hard. As for the regulation of the brake when you are driving it is best to set it during the road test. Find a piece of straight rarely used road and try using brakes. We are trying adjust the tension of the tie rods to a point when wheels of the trailer are locking only when we are hard braking.


During the short stops we propose to use the security protection on the coupling. These are simple and inexpensive clips that can easily be purchased „online”.







Another more troublesome for a thief invention is a lock on the wheel. It is more difficult to install and store but something for something.

But in our opinion the most reliable is Auto Casco  in a duet with secure car parking.

There is no doubt that the surest way to repair damaged tarpaulins is gluing and  heat welding. But there is not always a possibility for such a repair.

We propose to equip a repair kit for self-patching tarpaulin . While you’re away from the workshop you will be able in a very simple way save your time and money. The patch for self-sticking is a simple and popular tool that you should always have on hand when working with the stage.

When you notice that the roof of the stage at the end rises slower and less smoothly than normally, and the hydraulic pump is running unevenly and loudly, it means that you need to add hydraulic oil to the hydraulic pump reservoir. Insufficient oil in the tank is the most common and so far the only cause of improper operation of our hydraulic lifting system.

The oil level in the tank (when the trailer is fully folded and the trailer is in horizontal position) should be visible above the max indicator or on the top corner of tank (depending on the tank model).

The side platforms of the stage while opening are held by a set of gas springs. Every gas spring loses its power over time – up to 10% per year. This is a normal wear of this type of component. It also happens that the gas spring is damaged or unsealed and completely loses its properties. Such a spring is easy to identify because it is usually loose even when is installed.

The solution to this problem is replacing damaged or worn gas springs that are supporting the platforms.
