Assembling the Dragon

3.1 Shipping Crate

The Dragon A250 is shipped from the Bend-Tech manufacturing facility in a custom-fabricated

shipping crate. This crate features a steel reinforced floor and is fully-enclosed to ensure

the protection of the Dragon A250 during shipping. The Dragon A250 machine is completely

secured within the crate for shipping purposes. Components may be bolted to the crate,

shrink wrapped, or secured with plastic or metal banding. The order in which components

are uncrated is important in executing proper assembly of the machine. For best results in

assembling the Dragon A250, carefully follow the steps outlined in this Assembly Manual.

3.1.1 Dragon A250 Shop Position

Before beginning assembly, ensure there is adequate space to accommodate the machine

on the shop floor. Plan on reserving a minimum of 28-feet for the full length machine, if the

material cooling system is installed more room will be needed.
