The Chicago Pneumatic CP86101 is a 100-metric-ton air-hydraulic workshop press for professional maintenance and component assembly or disassembly work. Its 220,000 lb rating is equivalent to approximately 110 U.S. short tons. The air foot-driven pump handles fast ram approach, while the manual high-pressure stage gives the operator finer control as the tooling reaches the workpiece.

A movable ram, winch-operated bed, pressure gauge, mesh shield, arbor plate set, and eight punches equip the press for demanding shop work while giving the operator practical control over setup and load application. The 11.81-inch hydraulic stroke provides room for controlled pressing operations.

This is heavy industrial equipment with a published package weight of 766 kg, approximately 1,689 lb. It must be assembled, anchored to a firm level floor, supplied with clean compressed air, and given adequate working clearance. Confirm the receiving plan, floor location, and work envelope before ordering. Garage Supply Guys can help review installation and delivery requirements.

Features

Air-powered approach with manual fine control

The CP86101 combines an air foot-driven hydraulic pump with separate manual high- and low-pressure operation. Air power moves the ram toward the work quickly, while the manual high-pressure stage lets the operator apply load in smaller, more deliberate increments once the saddle is close to the workpiece.

100 metric tons of capacity with an 11.81-inch stroke

Chicago Pneumatic rates the press at 220,000 lb of compression force, equivalent to approximately 110 U.S. short tons, with a 300 mm hydraulic stroke. The large gauge reads in short and metric tons so the operator can watch applied force instead of treating full capacity as the default for every job.

Movable cylinder for off-center component geometry

The cylinder can be repositioned across the upper frame to align the ram with the required pressing point. That flexibility is useful when a large or irregular component cannot be centered by moving the workpiece alone, but the load must still be aligned correctly under the ram before pressure is applied.

Winch-operated bed simplifies height changes

A dedicated winch helps one operator raise or lower the press bed for different work heights. Two removable steel support rods secure the bed at the selected working level, reducing unnecessary ram travel while keeping the setup supported mechanically.

Mesh shield and press tooling are included

The CP86101 selling package includes a mesh shield, an arbor plate set, and eight punches. These components support common pressing setups while the workpiece and ram still need to be aligned, stable, and properly supported before force is applied.

Steel frame designed for permanent shop installation

The press uses a heavy steel frame with mounting holes in each foot. Chicago Pneumatic requires the machine to be anchored before first use on a firm, horizontal surface, making this a fixed workshop asset rather than equipment intended to be moved between jobs.

Best For

Vehicle and heavy-equipment maintenance
Suitable for professional shops that regularly press large service components during assembly or disassembly and need more capacity than a general-purpose light workshop press can provide. Tooling selection and work support must match the component and pressing operation.
Industrial maintenance departments
The movable cylinder, adjustable table, and air-assisted approach suit maintenance facilities handling components with changing heights and pressing points. The operator still retains manual control for the final high-pressure portion of the cycle.
Production support and repair workshops
A practical choice where controlled component assembly and disassembly are recurring jobs and the facility can dedicate permanent floor space, compressed air, mechanical receiving equipment, and trained operators to the press.

Installation Requirements

Plan for mechanical receiving and assembly

Chicago Pneumatic publishes a package weight of 766 kg, approximately 1,689 lb, and package dimensions of 197 by 50 by 117 cm, approximately 77.6 by 19.7 by 46.1 inches. The shipment requires suitable unloading and material-handling equipment. Confirm package count, carrier method, and site access before delivery.

Anchor the press before first use

Install the CP86101 on a firm, horizontal floor and anchor the mounting holes in its feet before operation. The supplied evidence does not specify concrete strength, slab thickness, anchor size, or anchor torque, so those values must come from the current installation documentation or a qualified installer rather than assumption.

Keep the operating area clear

Maintain at least 1 meter of unobstructed working space in front of and behind the press. Provide adequate lighting and enough side access to position components, adjust the table, operate the pump, and remove work without placing anyone in the load path.

Provide the correct compressed-air supply

The applicable operating instructions specify 7.5-8.5 bar, approximately 109-123 psi, for air-assisted operation. Confirm the air connection and filtration requirements from the final installation documents before connecting the press. Disconnect the air hose when work is complete.

Assemble and bleed the hydraulic system

Install the feet, table, pump assembly, pressure gauge, and hydraulic hoses as directed, keeping the gauge seal correctly positioned. Purge air from the hydraulic circuit before first use, and use the hydraulic-fluid type and fill quantity specified in the current installation instructions supplied with the press.

Commission the bed, tooling, shield, and controls

Confirm that both bed-support rods are fully engaged, the arbor plates and workpiece sit securely, the mesh shield is positioned for the operation, and the workpiece and ram align for centered loading. Verify control movement, unloaded travel, and pressure release before placing the press into service.

Frequently Asked Questions

Why is the CP86101 described as both 100 metric tons and approximately 110 U.S. short tons?
Chicago Pneumatic publishes a compression-force rating of 220,000 lb and a 100-metric-ton product designation. For U.S. buyers, 220,000 lb is approximately 110 short tons. These figures express the same published capacity in different measurement systems.
How does the CP86101 relate to the CP86100?
The CP86101 is the North American ASME-market configuration of Chicago Pneumatic's 100-metric-ton CP86-series workshop press, while the CP86100 is the corresponding CE-market configuration. They share the core press design and operating method, but documentation, certification, and included equipment should always be verified for the exact model being purchased.
Does the CP86101 operate from compressed air or by hand?
It supports both. The air foot control provides fast hydraulic movement, and the manual pump provides low-pressure fast approach plus high-pressure fine control. Once the tooling is close to the workpiece, the operator can use the manual high-pressure stage for more deliberate load application.
What air pressure does the CP86101 require?
The shared press manual specifies 7.5-8.5 bar, approximately 109-123 psi. Confirm the connection and air-treatment requirements in the final installation documents before hookup.
What equipment comes with the press?
The CP86101 selling package includes a pressure gauge, winch-operated bed, mesh shield, arbor plate set, and eight punches. The press uses an air-hydraulic pump system for fast approach and controlled load application.
Does the press need to be anchored?
Yes. Chicago Pneumatic requires the press to be fixed to a firm, horizontal floor before first use. The current evidence does not provide slab strength, slab thickness, anchor size, or torque values, so those details must be confirmed from the applicable installation instructions.
What warranty applies to the CP86101?
Chicago Pneumatic's standard U.S. limited warranty covers defects in materials and workmanship for one year from the original purchase date when the product is purchased new from Chicago Pneumatic or an authorized dealer. Dated proof of purchase is required, and exclusions include abuse, misuse, unauthorized modification, and unauthorized repair. Contact Garage Supply Guys for help with a warranty claim or service question.
