Some are in a restricted, controlled access applications and the number of personnel permitted to operate the equipment are limited. Some dock lifts are installed outside of the building at a retail or institutional facility, where it is necessary to ensure that they cannot be operated by the general public. To prevent unauthorized use, the controls can be removable, key operated or stored inside the building on a coil cord. The application dictates the most suitable dock lift controls to use.

Pentalift's exclusive PentaFlow cylinder design ensures long cylinder life, reduces maintenance, and eliminates oil spills. The PentaFlow cylinder is completely sealed from the surrounding atmosphere and all components are continuously bathed in fresh oil. Contamination and deterioration of the cylinder cannot occur. When the cylinder reaches full extension, the bypass valve opens and allows oil to flow through the piston to the rod side of the cylinder, out the port, and back to the reservoir. This prevents the cylinder from dead ending and building high stresses in the cylinder, equipment structure, and hydraulic system. Air in the cylinder is automatically ejected through the bypass valve. The need for manual bleeding which often results in oil spills is eliminated.

Once the cylinder requirements have been determined, then it simply becomes a matter of the volume of hydraulic oil that is pumped into the cylinders, more volume = faster lift times. Think of it this way; if it takes 2 minutes to fill a bucket with water using one garden hose and you want to fill it faster, add a second hose to the bucket. It will now fill in 1 minute. Back to dock lifts, to fill the lift cylinders more quickly, the power unit's hydraulic pump size is increased to push a higher volume oil. The horse power of the motor often needs to be increased to turn the bigger pump. Contact your Pentalift Sales Representative for more information.
