American Forge and Foundry 3584 Heavy-Duty Engine Crane - 6,000 lb. Capacity
Most shop engine cranes top out at 2,000 lbs. That's workable for passenger cars. But the moment you're pulling a diesel out of a commercial truck or bus, you need something built for the actual job. The AFF 3584 is rated at 6,000 lbs. at its first boom position. Three times the capacity of a standard crane, and built from the start for commercial truck and bus service shops where pulling light simply isn't an option.
Four boom positions give you the right combination of reach and lift capacity for whatever's in the bay. Stay at Position 1 for maximum strength at 6,000 lbs. with 35" of reach. Extend to Position 4 when you need 61" of reach to clear a wider engine compartment, with 2,000 lbs. still available. The 12-ton hydraulic ram includes a built-in safety overload so the crane can't be pushed past its rated limits. Reinforced leg and boom construction throughout keeps the unit from torquing and twisting under heavy load. This is the kind of heavy duty engine crane - and engine hoist performance - that professionals actually need, not just a number on a spec sheet.
Mobility matters in a working shop. The 3584 rolls on oversized 4-1/4" rear swivel casters and 6" fixed front wheels. Legs retract for tight maneuvering and extend wide when you're under load and need a stable footprint. ANSI-conforming construction means you're covered on the safety standards side. American Forge and Foundry Inc. has been making this type of equipment since 1963, and this 3 ton engine crane is part of why their products show up in commercial repair shops, military facilities, and heavy-duty service environments worldwide.
Order here and it ships free to the lower 48. With over 300 AFF service centers nationwide and a complete inventory of american forge and foundry parts, you're buying a crane with a real support network behind it - not a throwaway that leaves you stranded when something needs attention.

Installation & Setup
At 359 lbs. shipping weight, plan for proper receiving. The crane needs to be offloaded with appropriate equipment and positioned on a level floor rated for the combined weight of the unit and the load you're lifting.
Boom position selection is the most important setup decision you'll make before each lift. Position 1 delivers the full 6,000 lb. capacity with 35" of reach - use this when you're working close in on the heaviest loads. Position 4 extends reach to 61" for wider or deeper engine bays, with 2,000 lbs. available. Never exceed the rated capacity for the position you're in. The built-in hydraulic overload protection is a safety feature, not a substitute for selecting the correct boom setting before you lift.
Leg position affects both clearance and stability. Retract the legs when maneuvering between vehicles - the distance between the front legs goes from 23" retracted to 28-1/2" extended. Before any lift, extend the legs fully and confirm the floor is clear, level, and stable under all four contact points. Overall footprint runs 58" front to back with legs retracted and 86" with legs extended.
Applications
This is what the 3584 was built for. Diesel engines in commercial trucks and buses routinely exceed what a standard automotive engine crane can safely lift. The 6,000 lb. rating at Position 1 means you're not improvising your way through a heavy pull.
Engine cranes in busy shops take a beating. The reinforced leg and boom construction on the 3584 is built for that environment. Four boom settings mean one crane handles everything from small sedans to full-size trucks without swapping equipment mid-job.
AFF has supplied military sectors, municipal fleets, and private transport operations for decades. The 3584 is well suited to any fleet environment where vehicle diversity demands a crane that can scale up to heavier powerplants without limitations.
Engine removal on large agricultural machinery and heavy industrial equipment calls for more lift capacity than a foldable engine crane in the standard 2-ton class can offer. At positions 1 and 2, the 3584 handles loads that most shop cranes simply cannot.

Frequently Asked Questions
What is the maximum lifting capacity of the AFF 3584?
The AFF 3584 has a maximum capacity of 6,000 lbs. at Boom Position 1, which provides 35" of reach from the ram. Capacity changes with each boom setting: Position 2 is rated at 4,000 lbs., Position 3 at 3,000 lbs., and Position 4 at 2,000 lbs. with 61" of reach. Always select the boom position rated for the weight you're lifting before you begin.
How do the four boom positions work, and when should I use each one?
Each boom position trades reach for capacity. Position 1 gives you the most lifting power at 6,000 lbs. with the shortest reach of 35". As you extend toward Position 4, reach increases to 61" but capacity drops to 2,000 lbs. The right rule is to use the shortest position that still lets you reach your lift point - that gives you the maximum available capacity for the job.
What safety features does the AFF 3584 include?
The 3584 includes a built-in hydraulic overload protection system in the ram that prevents the crane from being operated beyond its rated capacity for the selected boom position. The hydraulic ram itself is rated at 12 tons - well above the crane's maximum working load - providing additional safety margin. The unit also conforms to ANSI standards for lifting equipment.
Does this engine crane ship for free?
Yes, the AFF 3584 ships free to any address in the lower 48 states. Call (855) 498-2147 with any questions about your delivery.
What does the AFF warranty cover on the 3584?
AFF provides a one-year limited warranty covering defects in material and workmanship from the date of purchase. If a defect is identified during the warranty period, AFF will repair or replace the unit at their option, provided it's returned with prepaid shipping and proof of purchase to AFF or an authorized service depot. The warranty does not cover damage from overload, accident, abuse, unauthorized modifications, or non-recommended attachments.
