Amerex 859 Dolly cart 7" and 8" Diameter OEM - 08289

The Amerex 859 Dolly Cart (OEM part number 08289) is the factory-designated wheeled transport solution for Amerex high-capacity fire extinguisher cylinders with 7-inch and 8-inch diameter bodies. Where hand-portable extinguishers can be carried directly to a hazard, larger wheeled units rely on the dolly as the primary mobility platform. The 859 is the OEM cart that ensures these heavy cylinders can be moved quickly, safely, and reliably by a single operator across flat and moderately uneven surfaces.

Constructed from welded steel with a black powder-coat finish, the 859 features a tall ergonomic push handle, a two-wheel axle assembly, and a cylinder retention band at the base that secures the extinguisher body to the cart frame. For fire safety contractors, facility managers, and industrial safety coordinators, utilizing the genuine Amerex OEM dolly ensures the cylinder and cart remain a matched, stable assembly that meets the ergonomic and load-bearing requirements of the extinguisher's design specification.

Welded Steel Frame

The 859 frame is welded steel construction finished in black powder coat, providing the structural rigidity needed to support the gross weight of a fully charged large-capacity cylinder. The wide base footprint and two-wheel axle placement keep the center of gravity low during transport, reducing the risk of tipping when the cart is in motion.

Cylinder Retention Band

A steel retention band at the base of the frame wraps around the cylinder body, securing it to the cart. This retention system prevents the cylinder from shifting or separating from the dolly during transport across uneven surfaces, doorway thresholds, or during rapid deployment toward a hazard.

Ergonomic Push Handle

The tall upright push handle allows an operator to tilt and maneuver the loaded cart without bending, reducing physical strain during deployment across a facility. The handle height is sized to the overall cart geometry to provide controlled leverage when tilting the cylinder back onto the wheels for transport.

The Amerex 859 is the correct OEM transport cart for large-capacity Amerex cylinders with 7-inch or 8-inch diameter bodies. Typical deployment environments include:

• Industrial facilities and manufacturing plants: Large dry chemical or CO2 extinguishers positioned in warehouses, production floors, and loading docks require a dolly for rapid single-operator deployment across long distances to a hazard.
• Commercial kitchens and food service facilities: High-capacity wet chemical or dry chemical units serving large cooking operations are mounted on dollies to allow kitchen staff to move them quickly without requiring multiple personnel.
• Aircraft hangars and fuel storage areas: Large-capacity wheeled extinguishers in aviation and fuel handling environments must be deployable by a single operator at speed. The 859 provides the mobility platform for this requirement.
• Service and recharge operations: Fire equipment service technicians use the 859 to transport cylinders during 6-year internal maintenance, hydrostatic testing, and recharge cycles, reducing the physical demands of moving heavy cylinders through a service facility.
• OEM cart replacement: When an existing dolly is found to be damaged, bent, or structurally compromised during an annual inspection, the 859 is the correct OEM replacement to restore the wheeled unit to its factory-specified configuration.

Cylinder Diameter Verification

Before mounting a cylinder on the 859, confirm the cylinder body diameter is either 7 inches or 8 inches as specified. Mounting a cylinder with a smaller diameter will result in an insecure fit within the retention band, creating a tipping hazard during transport. Mounting a cylinder that is too large can overstress the retention hardware and prevent the band from closing properly.

Retention Band Security Check

After mounting the cylinder, confirm the retention band is fully secured and the cylinder does not shift or rock within the cart frame. Any looseness between the cylinder and the dolly must be corrected before the unit is put into service. A cylinder that separates from the dolly during emergency deployment is a serious safety hazard.

Annual Structural Inspection

Per NFPA 10, wheeled extinguisher carts must be inspected for structural integrity during each annual service. Check the 859 frame for cracks, weld failures, bent members, and wheel condition. Inspect the axle hardware for looseness and confirm the wheels rotate freely. Any dolly showing structural damage must be replaced with a new 08289 before the unit is returned to service.

Surface and Terrain Considerations

The 859 is designed for use on flat and moderately smooth surfaces. Avoid deploying the cart on stairs, steep inclines, or heavily uneven terrain, where the two-wheel design provides limited stability under the weight of a fully charged large-capacity cylinder. In facilities where the cart must cross raised thresholds or surface transitions, approach slowly and maintain control of the handle at all times.

Will the 859 dolly fit Amerex cylinders with diameters smaller than 7 inches?

No. The 859 retention band and base cradle are sized for 7-inch and 8-inch cylinder bodies. Smaller cylinders will not be held securely by the retention system and should be paired with the dolly designated for their specific diameter. Always verify cylinder diameter against the cart specification before mounting.

Can the 859 be used with non-Amerex cylinders?

The 859 is an Amerex OEM component designed and tested for use with Amerex wheeled extinguisher cylinders. While the physical dimensions may accommodate some cylinders from other manufacturers with matching body diameters, Amerex does not certify the 859 for use with non-Amerex cylinders. Using the cart outside its OEM application may affect the unit's compliance status.

What should I do if the wheels or axle hardware are damaged?

A dolly with damaged wheels, a bent axle, or failed axle hardware must be taken out of service immediately. A wheeled extinguisher that cannot be reliably moved to a hazard provides no practical fire protection for its rated coverage area. Replace the 859 with a new OEM 08289 unit and have the cylinder remounted before returning the extinguisher to its designated position.
