Rapid-Response Trailer

This trailer is designed specifically by Allsopp Helikites Ltd for rapid mobile deployment of Helikites up to 45m3 in size.

Special features allow easy and safe inflation, launch, and retrieval of a Helikite in all weathers. It also allows Helikites to be towed at high speed behind vehicles, which is excellent for rapid surveillance, patrolling, TV, and movie work.​




Helium is not always available near the customer; sometimes it will be hundreds of miles away. This trailer can also safely transport and store up to 13 x BOC ‘L’ sized helium cylinders (or similar) each holding 9m3 (315 cubic ft) of helium over rough terrain. This is a total of 117m3 (4095cubic ft). Enough to fill and fly a 18m3 Helikite constantly for 12 months, or a 34m3 Helikite for 6 months.


Superficially, this may look similar to a modified standard trailer. However, it is in fact custom-made from the ground up.


No standard trailers made in the UK had high enough ground clearance, strong enough chassis, protected brake pipes, etc. So, we designed and produced our own from scratch.


A Helikite trailer needs to be supplied to the customer in a 20ft shipping container. It can then be instantly trailed using a standard ball hitch, directly from that shipping container both on and off-road – anywhere in the world. It also needs to be air-transportable for military or humanitarian operations, so it must fit in standard transport aircraft. Great for PGSS systems, PTDS systems and long-range UAV systems.



  • Massively strong, custom-designed chassis.

  • Deep section in the centre, then rising at the stern to cope with uneven ground.

  • Large, moveable side bars gently hold the inflating and inflated Helikite in place and keep it off the rough ground during gas filling.

  • Solid steel construction, fully galvanised after all work has been done, to ensure no bolt holes will rust.

  • Side bars allow Helikite to be held sideways, thus allowing the fully inflated Helikite (under 20m3) to travel on public roads.

  • Side bar upholstered in thick padding in client’s preferred colour. Padding attached with Velcro and so can be removed if required.

  • Twin axle for greatest reliability, best towing stability, and lowest ground pressure.

  • High ground clearance to cope with the worst rutted tracks in Africa, South America, or anywhere else.

  • ‘Upside-Down’ axle with protected brake pipes ensured the brake pipes cannot be damaged by rocks or ruts etc.

  • Custom-made 12V high speed winch (60ft/min) is suitable for Dyneema flying line (normal winches are slow and melt tethers).

  • Padded floor area over the helium cylinders, to ensure balloon is not damaged during inflation and payload is always protected.

  • Unique triangular section steel supports + tie-down straps to hold numerous helium cylinders in place for safe transport.

  • Side flaps stop helium cylinders from sideways movement but allow easy access when required.

  • Composite galvanised steel + phenolic resin plywood floor. Great strength and resistant to scratches from helium cylinders.

  • Helium, winch, Helikite and battery storage.

  • Winch operated via cable remote control.

  • Lockable steel toolbox on front of trailer also acts as a platform for an operator to stand on.

  • Lockable Helikite storage box.

  • 4 x trailer legs

  • Two spare trailer wheels.

  • Special roller ramp to easily lift helium cylinders onto trailer.

  • Waterproof and dustproof cover.

  • Painted in any customer-preferred colour.

  • Helium transport warning signs.
