JFB Adjustable Heavy Duty Transport Trolley – K Series
The JFB adjustable transport trolleys from JUNG form the rear-support section of the K Series machinery moving system. Two load cassettes are connected by an adjustable bar, allowing the support width to be adapted to different machinery dimensions. Capacities are available from 3 tonnes up to 12 tonnes.
- Two load-supporting transport cassettes
- Adjustable connecting bar to suit load width
- Low 110 mm installation height
- JUWAthan®plus low-wear castors
- Designed to work with matching JL or JLB steerable trolleys
Adapt the trolley width to the machinery
Heavy equipment can vary considerably in width and footprint. The JFB system uses two separate transport cassettes connected by an adjustable bar so the support points can be positioned to suit the dimensions of the machine being moved.
Adjustable Width
Change the distance between the two trolley cassettes to accommodate different machine widths.
Twin Load Support
Two separate cassettes distribute the rear portion of the machinery load.
Low Profile
The 110 mm installation height keeps the clearance required beneath the machine to a minimum.
Complete K System
Combine JFB with the appropriate JL or JLB steerable trolley to create a complete transport set.
The adjustable rear section of the transport system
The JFB trolley is positioned beneath one end of the machinery. Its two load cassettes support the weight while the connecting bar maintains the required distance between them.
At the opposite end of the machine, a JL or JLB steerable trolley provides directional control. Together, the two components form a complete machinery transport system.
The adjustable layout allows the rear support position to be adapted to a range of equipment widths without requiring a completely different trolley arrangement.
Choose JFB when you need the adjustable rear support component of a K Series machinery-moving system. It should be matched with the appropriate JLB or JL steerable trolley according to the required capacity.
Adjustable support for heavy machinery movement
JFB transport trolleys are designed for machinery moves where the rear support needs to accommodate different load widths while maintaining a low installation height.
Production Machinery
Support manufacturing equipment during relocation, installation or production-line changes.
Wide Equipment
Adjust the distance between the rear cassettes to suit machinery with different footprints.
Plant Maintenance
Move machinery away from its operating position for servicing, repair or replacement.
Industrial Relocation
Support controlled movement of heavy equipment within factories, warehouses and workshops.
JFB, JLB or JL – what is the difference?
The K Series separates steering and rear support into different trolley types. The correct combination depends on the weight and dimensions of the load.
JFB Adjustable Trolley
Adjustable twin-cassette rear trolley for supporting the opposite end of the machinery.
JLB Steerable Trolley
Compact steerable trolley for lower-capacity K Series machinery transport systems.
JL Steerable Trolley
Higher-capacity steerable trolley for heavier machinery-moving applications.
JFB K Series capacities
Four standard JFB capacities are available, allowing the adjustable rear trolley to be matched with the corresponding steerable trolley.
| Model | JFB Capacity | Matching Steerable Unit | Complete Set Capacity | Height |
|---|---|---|---|---|
| JFB 3 K | 3 t | JLB 3 K | 6 t | 110 mm |
| JFB 6 K | 6 t | JLB 6 K | 12 t | 110 mm |
| JFB 9 K | 9 t | JL 9 K | 18 t | 110 mm |
| JFB 12 K | 12 t | JL 12 K | 24 t | 110 mm |
Complete set capacities refer to the corresponding JFB rear trolley combined with the matching JLB or JL steerable trolley. Correct load distribution is essential. Final equipment selection should consider load weight, dimensions, centre of gravity, floor condition and available manoeuvring space. Specifications may be subject to manufacturer updates.
Designed for flexible machinery support
JFB combines adjustable load support with the same compact K Series installation height used by the corresponding steerable trolleys.
Adjustable Bar
Allows the distance between the two support cassettes to be adapted to different machinery widths.
Reduced Weight
Optimised cassette construction helps keep the trolley system manageable when positioning it beneath loads.
JUWAthan®plus
Ball-bearing castors use a durable low-wear coating for controlled heavy-load movement.
Ready to Use
Each adjustable trolley consists of two transport cassettes and the connecting bar required to form the rear support assembly.
