S-61 with HB 2000

HB 2000

The Heli-Basket® is a multiple person rescue device that enhances the capability of any Helicopters rescue misssion. The design derived from the need to maximize the numbers of rescuees in a single mission, and minimize recovery time during the life crtitical "Golden Hour".

The equipment design is based on the lightest structure that demonstrates aerodynamic stability in flight, ease of entry, ease of delivery and recovery, and safety in land and sea operations

The Heli-Basket® is not CG sensitive. It maintains aerodynamic stability regardless or load placement, manouver or air speed. It has been test flown with symmetrical and asymmetrical loads at speeds up to 120kts without any adverse aerodynamic effects. The US Army Soldiers Systems Center tested and authorized the HB2000 Heli-Basket® for cargo flight at 100kts at Gross Weight (5100Lbs) and 120kts Empty (600lbs) for all military helicopters.

The in-flight stability of all Heli-Basket®s is derived through a combination of aerodynamic features of the basket and the lifting and oscillation dampening features of the spreader frame assembly. Below are suggested procedures when using the Heli-Basket® for utility operations or for emergency rescue operations over land and water.

NOTE: The Heli-Basket® is a utility device and requires approvals for rescue-for-hire operations. However, in emergencies the Heli-Basket® can be used to save lives wherever Good Samaritan laws apply or Government and or Military authorities have approved usage.

Heli-Basket® Design Considerations

HB 2000

Oblong link to connect to a high strength long line of synthetic fiber rate to carry a 6000 lb. load with a 13:1 safety factor. A Heli-Strap provides additional safety

A Four Leg Sling is manufactured from galvanized aircraft cable with a maximum working load of 2880 lbs. per leg with a 5:1 safety factor

Heli-Basket® is ready to fly with a complete package, including a multipurpose spreader bar, tie-down straps, safety net, and cabling

Engineered for structural integrity and protective functionality. Handrails provide additional support to passengers while design still allows for easy breakdown and storage

Proven structural design from FEA and real-world limit testing proves the integrity of the basket as the load is transferred from the floor to the cables

Each Precision Lift Helibasket® is comprised of corrosion resistant T6 aluminum and coated with a high quality powder coat, ensuring protection from the harshest elements

Heli-Basket® Finite Element Analysis

Finite Element Analysis: Hinge

Finished Hinge
The Heli-Basket® design includes a complete finite element analysis on each individual component.

As you can see in these pictures, the hinges, an extremely critical part that will carry much of the weight and stresses of the Heli-Basket®, is analyized.

The picture on the left depicts the stresses characteristics drawn by our design software at one of the calculated stress levels. Each of the components were drawn and defined with the proper materials characteristics. We then designed a test plan for the software to test the components at different load levels and stresses that related to the actual use of the product under normal load and under loads that would be considered the extreme in each of the parameters. All of the parts were subjected to this level of design scrutiny before the first chips were cut to create the parts.

The picture on the right is a 3D representation of the part after the design characteristics and material specifications have been completed to correspond to the same parameters that were used in the finite materials analysis. In this manner we are able to produce the best and safest product that is demanded by our customers.

Heli-Basket® 3D Assembly

HB 1000
In completing the design of the Heli-Basket®, each piece part from the Biil of Materials was reproduced in 3D at its exact size and shape. The materials for each of the piece parts was utilized in the definition and for each piece part that required a finishl, the finish was placed on its respective components.

The Heli-Basket® was then assembled in a 3 D representation of the finished product. By completing this step, Precision Lift was able to accomplish several objectives.

A: The fit of each of the parts was checked.

B: The interference of assembly caused by the addition      of finish buildups can be checked.

C: The complete assembly can be stressed tested as a      unit which enhances the reliability of the complete      product.

D: The overall appearance and general finishes can be
     compared to the original artwork to determine if the      product is what was originally conceived.

Quote from our Design Team

Using the complete capability of our software, we are able to design, complete finite testing of individual components and piece parts and test for interference and fit of the completed product. These capabilities allow us to produce a very safe and strong product and meet the pricing requirements of the marketplace. Nothing should be or is compromised when we are designing for products that are used with human cargo.
