How much weight can these gantry cranes lift?
All models in this series are rated at 4,000 lb. The specifications list a capacity range of 4,000 – 4,000 lb, so capacity does not increase or decrease as you move up in size or price — only the dimensions change. Remember that the hoist, trolley, and rigging count against that rating, not just the load itself.
What sizes and models are available?
There are 27 models, with sizes listed from 8"×8" through 15"×10". The size appears in both the model number and the description: AHA-15-8-8-PNU is listed as 8X8, and AHA-4-15-10-PNU is listed as 15X10. Span and height are set by the model you order, so measure your floor space and overhead clearance before selecting one.
Why does the price range from $527.40 to $9,672.57?
Because this page covers both complete cranes and caster components. AHA-PNU-RF at $527.40 is a retro-fit pneumatic caster item, with AHA-PNU-DT-RF at $1,013.65 and AHA-PNU-DT4-RF at $4,054.65 covering dual-tire versions. Complete cranes begin at $3,284.09 for AHA-15-8-8-PNU and reach $9,672.57 for AHA-4-15-12-PNU. Check the model number before ordering so you get the item you expect.
Do these cranes require electrical power or an air supply?
No power requirement is listed in the specifications. There is no voltage, motor, or compressed-air data in the product information for any of these models, and the descriptions cover the gantry structure and casters — a hoist is not listed as part of any model. Plan for your hoist and its power source separately.
What do the pneumatic casters change compared with hard wheels?
Pneumatic casters are the common feature across this group — every model number ends in PNU. Air-filled tires roll more easily over rough or uneven ground than hard wheels, which suits yards, docks, and shop floors that are not perfectly smooth. Dual-tire caster items are listed separately as AHA-PNU-DT-RF and AHA-PNU-DT4-RF.
Where are they made and what warranty applies?
They are made in the USA by Vestil Manufacturing and carry a 1-Year Limited warranty. That is the full extent of the coverage stated in the product data for this series. Anything not listed in the specifications — including freight, lead time, and returns — is not part of these warranty terms and should be confirmed before you order.
