Pintsch Bubenzer launches electric wheel brake for cranes

Flemington, NJ, - Pintsch Bubenzer has launched a new, environmentallyfriendly, electric wheel brake, the BRBe, for electric overhead travelling cranes in heavy duty applications.

The BRBe is currently available for cranes with wheels from 500mm (19.68 in.) to 1,000mm (39.37 in.) diameter and wheel flange widths from 160mm (6.29 in.) to 254mm (10 in.). It is suited to paper mills, logging cranes, mobile and harbor cranes, steel mill outside service cranes, stacker and bulk storage cranes.

The most common sizes for the new range are the BRBe70, with 56000N braking force (70kN contact force); and the BRBe90, with 72000N braking force (90kN contact force). The brake can be sized up or down based on the application along with adaptation to the bolt pattern of existing wheel brakes or retrofitted to a new application.

Joel Cox, president at Pintsch Bubenzer USA, said: “The product is greener and avoids the typical hydraulic cylinder repairs or potential for leaks and contamination at docks. Our BRB120 and BRB90 designs are popular hydraulic wheel brakes, but this was built with greater ease and simplicity in mind both for original equipment manufacturers (OEM) and end users.”

Cox stressed that installation of the new brake does not eliminate the need for runaway or storm brakes. “Specifications still call for storm brakes,” he said. “And ports, for example, still use mechanical tie downs during hurricanes and big storms when they have time to prep for them. Our wheel brakes are good to keep the crane from rolling and preventing them from catching momentum down the runway. It is up to the end client or OEM discretion whether to use wheel brakes, push down (on rail) brakes, or rail clamps for everyday use.”

The BRBe, which can be retrofitted, is designed for outdoor cranes, such as ship-to-shore, rail-mounted gantry and rubber-tired gantry cranes.

The electric wheel brake originated from the RWBe, a green concept that removed all hydraulics. Pintsch Bubenzer added its new BUEL thruster line-up, which had a traditional thrusting version (H model), a self-contained HPU version (G) and a version for storm brakes (S) that would pull and not thrust. The new, all-electric version is used with the BUEL S model. The BUEL G is used to remove traditional HPU units on other applications not related to traveling motion.

Cox said: “The [BRBe] unit is already showing up on cranes in the USA and has environmentally friendly design since it requires no oil change, lifetime internal filling and intermittent operation. It requires no bleeding, no special wiring, and no pipes or hoses to worry about. Further, operation is coil spring applied.”
