Description:

For use with FTI’s patented Split Sleeve Cold Expansion process. The MB puller unit is designed to pull a mandrel through a hole with the pre-lubricated stainless steel split sleeves used in this process. The MB pullers have a maximum pull force of 24,000 pounds (1.1 x 105N) at 10,000 psi (689.5 bar) pump pressure. The MB is available in sizes (models) capable of cold expanding holes up to 1 inch (25.4 mm) diameter and 7 inches (177.8 mm) deep in aluminum, and up to 7/8 inch (22.2 mm) diameter in steel and titanium. The Medium Brute is available in various models to accommodate multiple material stack-ups, including "-V" models with high-visibility hose markings. The Medium Brute has a fail-safe air control system that causes the puller retraction cycle to be interrupted whenever the operator releases finger pressure on the trigger or in the event of air or hydraulic hose failure. All puller units operate in conjunction with either of FTI’s PowerPak air-hydraulic power units, the standard FT-200 or portable FT-20 (and compatible with older units IW100MF and IW10MF). The MB has proven to be very reliable, and requires minimal maintenance.
