Technical Information for the Uhlmann Giant Umbrellas - The Quality is in the Details

The Uhlmann Giant Umbrellas are available in three types, T, TL and TLx. The type also references the size of the umbrellas, and the materials used in their mast and supporting structure.  The larger umbrellas, over 10 meters diameter, require stronger and sometimes different materials to support their strength and stability than the smaller ones. But there are also many common features between the Type T, Type TL and TLx umbrellas.

The Frame

1. The frame of all three types are powder coated white aluminum profiles that resists peeling, chipping, rusting and oxidation, therefore remain easy to clean, maintenance free and permanently appealing.
2. Their construction is solid, their strength and wind resistance is well above average. Our umbrellas passed the extensive load and rigidity testing by the German non-profit quality and safety control institute, and we are proud to carry their quality seal "Production Monitored - Safety Tested".
3. The roof arms are rigid, the lower parts are reinforced with interior pipes.
4. The connecting joints between the roof arms and the supporting arms are made with U channels.
5. All joints are manufactured from high grade steel, while those exposed to the elements are made of stainless steel.
6. The corner arms of our square umbrellas are reinforced with strong aluminium tubes to provide additional strength.
7. The main arms are adjustable, making it possible to easily adjust the tension of the roof covering material and allowing the cover to be removed with ease.
8. All arms are individually removable and exchangeable without special tools.

The "StrongWind" Umbrellas recently passed a TUV supervised wind tunnel test at over 100km or 60 miles per hour. To see video of the test visit our StrongWind page.

The Mechanics

1. All Uhlmann Giant Umbrellas are telescopic.
2. The telescopic umbrella with cranked lever operation is exceptionally strong, ensuring high wind stability and durability.
3. The Type T umbrellas (including the StrongWind) operate with a fixed hub. Roof arms are attached individually to the telescope plate, and each supporting arm is mounted individually to the mast plate.
4. The mast plate is welded to the mast.
5. The Type TL and TLx operate with a slider in addition to the telescope. (Movable hub). The roof arms are mounted individually to the telescope plate and the supporting arms are individually bolted to the slider plate. The slider is connected to the telescope with two stainless steel wires.
6. The telescope and the slider are moving together (but in opposite direction), enabling the very easy operation of the umbrella.
7. The telescopic part moves on high density plastic bearing and guided to prevent rotation and twisting.
   
8. The maintenance free gear box (built into the mast) rotates the special spindle lift which is moving the telescoping part.
9. The cranked lever is very safe and easy to operate. Even the largest umbrellas can be raised or lowered by a child.

The Drive

1. The gears are specially treated to withstand maximum torque.
2. The gear-box is built into the mast. It is maintenance free with lifetime lubrication.
3. The spindle lift runs in a closed tube, preventing corrosion and providing smooth operation.
4. The drive crank handle locks the spindles automatically in every opening/closing position, to prevent accidental opening or closing of the umbrella.
5. The cranking handle is removable.

The Installation

The Uhlmann Giant Umbrellas can be installed either permanently or they are re locatable for easy and safe operation. In both cases the stability of the installation is the primary objective.

1. When the installation is permanent, a ground sleeve is imbedded into concrete, and the mast is stabilized once by a
2. special clamp on the rack pipe of the ground sleeve, and again by a counter screw at the mast. This method holds the mast securely and firmly and provides absolute vertical stability.
3. The base stand is fully galvanized and powder coated to match any requirement, or match the color of the umbrella.
4. When surface installation is used for movable application, four each 50 x 50 cm concrete balance plates hold down the galvanized and welded steel base plate firmly, counter-balancing the structure. The balance plates are laser cut for precision fit.
5. For portable application the TL and TLx umbrellas are usually installed with 8 each 40  x 40 cm balance plates.
6. The four corners of the base frame are individually and easily adjustable to eliminate the possible unevenness of the ground.
7. To further increase the flexibility and easy of use, the base plate can be installed on rollers.
