Fully Automated Hydraulic Tool Arm:

One of the most important advantages of the Coats CHD-9551 is its fully automated hydraulic tool arm. Unlike machines that require technicians to manually reposition the tool arm, the CHD-9551 uses remote-controlled hydraulic operation to simplify positioning and tire changing procedures.

This automation is particularly valuable when servicing large agricultural, mining, and off-road tires, where tire size and weight can make manual adjustments difficult and time-consuming.

Remotely Controlled Rotating Tool Head:

The CHD-9551 features a remotely controlled rotating tool head that allows technicians to position the mounting and demounting tools without manually rotating the assembly.

This feature helps streamline tire changing procedures and reduces unnecessary operator movement when working with large wheel assemblies.

Four-Jaw Hydraulic Clamping Chuck:

The Coats CHD-9551 uses a powerful four-jaw hydraulic clamping chuck designed to securely hold heavy-duty wheel assemblies during mounting and demounting operations.

The floating jaw design helps accommodate different wheel contours and provides reliable gripping performance across a broad range of compatible commercial, agricultural, and off-road wheel configurations.

With standard rim capacity from 14" to 46", the CHD-9551 can accommodate a wide variety of heavy-duty applications. Optional clamp extensions increase the maximum rim diameter to 56".

Exceptional 95" Tire Diameter Capacity:

The Coats CHD-9551 is engineered to handle oversized tire assemblies that exceed the capabilities of conventional truck tire changing equipment.

With a maximum tire diameter of 95", maximum tire width of 51", and wheel assembly weight capacity of 3,970 lbs., the CHD-9551 is suitable for demanding heavy equipment service operations involving compatible agricultural, skidder, earthmoving, mining, and commercial truck tires.

Actual compatibility depends on wheel construction, rim dimensions, tire configuration, and the accessories required for the application.

Portable Wired Control Station:

The standard portable wired control station allows technicians to operate the machine from a convenient position while maintaining visibility of the wheel assembly and mounting tools.

This flexibility is particularly useful when servicing oversized tires that require technicians to work from different positions around the machine.

Optional Wireless Remote Control:

For additional operating flexibility, the CHD-9551 can be equipped with the optional Coats Wireless Remote Control, Part #89238598.

The wireless control allows technicians to move around the machine without managing a control cable, providing greater freedom when positioning and servicing large wheel assemblies.

Designed for Agricultural, Mining and Off-Road Tire Service:

The Coats CHD-9551 is particularly well suited for facilities that regularly service large agricultural and off-road tires.

Its automated tool arm, hydraulic clamping system, and exceptional wheel capacity make it a practical choice for agricultural equipment dealers, commercial tire service centers, mining operations, construction equipment maintenance facilities, and heavy equipment repair shops.

Optional accessories are available to support specialized wheel configurations and tire service applications.

Heavy-Duty Single-Piece Frame Construction:

The CHD-9551 features a durable single-piece frame designed to provide stability and dependable operation when handling heavy wheel assemblies.

This construction supports the machine's substantial wheel capacity and helps minimize unnecessary complexity in demanding service environments.

Installation Requirements:

The Coats CHD-9551 requires a suitable installation area with adequate floor space, electrical service, and clearance for handling oversized wheel assemblies. The machine measures approximately 112"W x 81"D x 75"H, excluding any additional operating clearance required for wheel handling and technician access.

The manufacturer's brochure specifies 208–230VAC, three-phase, 60Hz electrical service. Customers should confirm the exact electrical requirements with the current installation manual and their installer before ordering.

Due to the machine's substantial weight and size, customers should also verify delivery access, unloading equipment, floor requirements, and installation arrangements before purchasing. Professional installation and operator training are recommended.
