Cutler Hammer Brake Before Kor-Pak Recondition

 

Benefits of Cutler Hammer GH505 Shoe Brakes

Cutler Hammer brakes are especially ideal since they have fewer moving parts than other DC Magnet brakes.  This allows for fewer maintenance costs and an economical choice for reconditioning.  Furthermore, it can fit well in tight spaces which can be ideal for certain applications.  Cutler Hammer brakes can be used on both AC and DC cranes (need resistor for AC cranes).  Gh505 brakes are offered with either shunt or series wound coils, and Kor-Pak offers both surplus and aftermarket options as well which can be more economical without compromising quality and performance.

Kor-Pak has several GH505 DC brake assemblies and spare parts in stock; please peruse our website to see what we have in stock, and contact a Kor-Pak representative today with any questions.
