Power-Packer, a manufacturer of position and electro-hydraulic motion control solutions for custom applications, is releasing an all-new heavy duty stabilization system to the off-highway market.
Power Packer’s heavy duty series of stabilization legs are the result of a thorough evaluation of the current market needs which require heavy wall tube design, integrated valve blocks, thicker mounting plates, and lift capacities up to 85,000 lbs. (38,555 kg) at 3,000 psi and mechanical load holding to 175,000 lbs. (79,378 kg). The system can handle 10 to 20 percent side load capacity depending on stroke. Stroke lengths range from 12 to 63 in. (30.5 to 160 cm). Optional upgrades include the newly designed universal footpad and mechanical locking feature.
Targeted to vehicles in the construction, drilling, and mining markets, the systems are engineered for performance in applications that require increased capacity, increased side loading and harsh environment capability.
Recognizing the importance of safety in these target markets, Power-Packer has incorporated several design elements into the heavy duty systems that enhance safety. The system is equipped with counterbalance valves, which provide a relieving function and integral load holding. The relieving function optimizes performance, reduces leak points and protects against thermal expansion. Integral load holding creates positive load holding in case of pressure loss. Integrated dual counterbalance valves also virtually eliminate potential for catastrophic failure when valve is remotely located. Leak potential is reduced due to the incorporation of these features, and the use of SAE fittings.
Power-Packer’s heavy duty system is designed for ease of assembly and superior functionality. The heavy duty system comes with outer mount tube included. Mounting brackets that can be customized for each application are integrated on the outer mount tube. This facilitates easy and fast removal for servicing or repair. An internal port location reduces the start air bleed requirement and avoids air entrapped in oil which may cause hydraulic system component wear. O-ring seals in the rod head prevent contamination between the weld tube and cylinder outer tube, while dual guide rings protect contamination from entering the exterior tube wall.
