Here are a few innovations that awarded us the title of leader in the mobile stage industry.

1.True-track engineering
Engineering a mobile stage is complex as it must function as a trailer, a heavy-duty hydraulic equipment, and a stage. True-Track Engineering combines a custom built trailer composed of multiple hinged and telescoping structures that will not alter in performance from mileage and bad roads. True-Track results in superior road handling and safety year after year.

2.Total control of the installation
Pre-assembled rigid structural panels unfold hydraulically and sequentially. Locking devices and pins are incorporated into every step of the set up ensuring total control of the installation in complete safety. Totally self-standing, the stage does not need to be secured with ballast and cables to maintain its stability and structural integrity.

3. Customized hydraulics with back up
Calibrated power for precision designed cylinders and components yield a perfect flow with safe, well-timed speed of operation. Comes with safety valves that block the liquid throughout with minimum effort and operation. Very low maintenance.

4. Raising and lowering the roof securely with double masts with lifting mechanism
A set of sturdy masts lifts and lowers the roof and show support equipment. They function with balanced or unbalanced loads even in difficult weather conditions.

5. Rigging of show support equipment made easy at ground and deck level
Industry standard rigging points, trusses and beams facilitate the installation of equipment. Cuts down on climbing and set up time.

6. Fiber lock panels
In closed position the roof panels of the stage become side panels of a hard-shell trailer. Fiber Lock is a process where fiberglass is wrapped around the frame. This method has multiple functions to address esthetics and durability. Both structural and weather protective, this layering process compensates for movement and structural deflection of the panels when they are hydraulically deployed. The process eliminates damage from road vibrations and extreme weather conditions. The fiberglass panels never need replacement, and they remain safe and great looking year in and year out.

Stageline primarily manufactures mobile stages and peripherals. Since we work closely with local sound and light providers, we would happily refer you to them when you purchase a mobile stage, as they are experts in their line of business.

You can transport and tech any purchased Stageline stage yourself if you have the appropriate licenses, insurance and Stageline operator’s certification. Stageline offers a comprehensive training course tailored to its each individual model available here.

Stageline products are like elite athletes, which means they offer their best performance when they’re maintained accordingly to the best practices. A maintenance checklist for getting your Stageline stage tuned up and ready for the season is available here.

Stageline mobile stages are designed, engineered, and purposely built to be safely transported, safely operated and safely used outdoors.

Safely transported
The custom-built chassis and trailer result in superior road handling as the stage is the trailer and comply with highway regulations.

Safely operated
Our stages are safely levelled even on uneven terrain. They are pre-assembled staging structures composed of heavy panels that unfold hydraulically into a self-standing covered stage. Never at any moment during the installation sequence is the stage unsafe for crew and technicians. Most of the work is done at deck level reducing the risk of potential human error and accidents. Stages are installed by Stageline certified technicians who follow step by step procedures. Our stages are self-standing covered stages, they do not rely on guy wires, anchoring and ballasts. They require no ground preparation or anchoring.
* Additional ballasts might be needed for certain peripheral options and equipment on the SAM series.

Safely used outdoors
All of our stages have a wind resistance up to 115mph/185 km/h without windwalls and 77mph/123 km/h with waterproof vinyl windwalls. We provide our clients with a dedicated procedure in case of high wind that is also cover in training. All units have mechanical locking systems on all moving parts and all hydraulic components are equipped with safety valves. All models are designed to withstand extreme weather conditions, and are tested with a 2:1 safety factor.

On our website, we give the information based on what we control which is set-up of the stage structure itself. The installation of motors, sound, lights, LED screens, banners, and additional options will affect the real on-site set-up time. The best way to determine the total set-up time for your event is to communicate with one of our logistics agents. The qualification and number of people in the crew provided, along with the unpredictable mood of Mother Nature will also impact the time needed.

Rubber wood pads are required under specific legs of your stage to prevent slippage due to high winds. If the structure was to start to slip from its initial position, it would create a side load which stage stabilizers are not designed for. Rubber pads have a ground coefficient of friction 2 times higher than a regular wood pad. Using a stage without properly placed rubber pads will significantly reduce your wind resistance.

When a Stageline mobile stage is purchased, Stageline issues a complete engineering certification free of charge and valid for the year of purchase. It gives you, your clients and the local authorities a proof that your mobile stage is in a good working condition and safe to operate. We recommend you renew these certificates every year, but they are valid for up to two years. Renewal process is simple and very important.
Your mobile stage will need to be inspected by a competent authority to evaluate its condition. Stageline can obviously help with that. After the inspection report, the critical defects repairs must be done before Stageline can issue the new engineering certificate. Since your stage can’t be operated without it, make sure you plan enough time to go through the whole process before your season starts. Keep in mind that in certain cases this process can take up to a few months.

The ultimate goal of the structural inspection and certification process is to keep the public, your crew and clients safe and sound. Engineering certificates are available upon request via this form.

From a model to another, and even from a stage generation to another, banner sizes will vary. It is important to validate this information with your stage provider.
If you are renting the stage, the following steps are highly recommended:
1.Ask your stage provider the banner information serial number of the unit that will be used for your event.
2.Confirm with your stage provider that all banner hardware is included with your rental since it may be optional.
3.If needed, you can contact us to request the banner documentation by filling this form.

Yes! On all Stageline stages rigging equipment can be installed before the roof is raised to avoid climbing. This speeds up the installation time and keep your crew with their feet on deck.
Some models will even offer lifting capacity to avoid the usage of motors or chain hoists. We suggest you revert to the technical specifications of the specific model for details.

No, all Stageline mobile stages are designed so you can fly your sound, often from several different locations and with different configurations to also allow for LED screens to be rigged.

Stage stability is ensured by stabilizers and legs set down on the ground. The ground must be firm enough to support the concentrated loads applied by these supports. Sinking trailer tires is a sign of the weak capacity of the ground. If tires sink more than 1 inch to 1 1/2 inch, do not set up the stage at that location. Contact a geotechnical service provider for more information and instructions.

Engineering support and analysis will be required when installing the stage on an uncommon area such as a bridge, an overhead structure, a boat, a beach, etc. Also make sure that you have enough space above and around the unit to deploy it safely.

All the information related to dead load ground support can be found in the Dead load ground support section of the technical drawings documents. Please note that the worst case scenario for setting up your stage will be to level the trailer when it is set up on the four main outriggers. The load on the ground will then be equivalent to ¼ of the weight of the trailer on each stabilizer.

A psf or kg/m2 is a distributed load. It is a pressure that is applied on a larger area and not a punctual load. For example, a snow-covered stage roof creates a distributed load on the structure. A light fixture hanging from the ceiling represents a point load.

Understanding the difference between concentrated loads and uniformly distributed loads will be important when you’ll analyze your rigging plans.

If the battery isn’t keeping its charge, it needs to be charged for 24h with the 120VAC outlet. The tractor is also charging the battery during transport for these units but might not be enough to keep it fully charged depending on your travel distances. If no 120VAC is available, you can also use the jump-starting studs to boost the battery.

Here is a checklist to help you resolve the issue. You can also visit Honda’s GX160 official page for more information. If it is a recurrent problem, please contact after-sale service team for further assistance.
