Popular with canal and river work because
1) It is the smallest pontoon you can work from at height. It is suitable for a raised scaffold platform or a Monkey Tower to give reach heights up to 4m.
2) It is narrow enough to launch on small slipways and light enough to lift with a lorry mounted HIAB.
3) At 3m wide it can be used on a narrow canal or river that is navigable and not block the waterway.

A 20 or 30 hp outboard mounted in one of our small engine frames and controlled by a clip-on console with steering and throttle gives a service speed of around 4 knots. Alternatively we can supply a separate safety/work boat to manoeuvre it into position.

Note: This is a full list of safety equipment for Category D waters. Other categories of water will require less safety kit and the equipment supplied will be adapted to the circumstances of the job.
As standard, all our pontoons come with a stability board produced by our Naval Architect, TG20 compliant edge protection and MGN469 compliant safety equipment.
We also supply a specific load assessment and limits for the planned scope of works and additional certifications when necessary or requested:
Our floats are available only for hire, and we are very strict about this, even though people constantly ask if they can buy the floats. We do this to maintain control over how the system is used. We make sure that every project has a proper design and stability assessment, and that we have overseen or checked the RAMS. Safety is one of the things our customers like most about ScaffFloat. Therefore, it is vital that we maintain our track record, and to do this we need to retain some control.
The Marine side: We work within the frameworks of several regulatory bodies which cover manning, safety equipment, stability standards and minimum freeboards
Scaffolding Regulations: Most of TG20:13 and other scaffold regulations are not relevant to what we do, but we do use elements of it for things like edge protection.
Lifting:
Structural Design: If the project requires it, we use the below frameworks to assess structure. On larger projects we can also offer customers an independent Cat 3 check by our partner Richter; this gives our customers reassurance that we have taken a safe and prudent approach to our design and planned method of works.
