Why Is There a Choice to Have Self-Contained or Remote Power Units for Dock Levelers?

Self-contained power units cost less and are the most common, however, there are alternatives. Remote power units are one of the alternatives and are best suited for wash down applications. When periodic maintenance is required, it is easier to access a remote power unit. At the time of installation, remote power units are typically installed 7’ – 8’above finished floor level on a wall mounting bracket. This moves the power unit up and away from potential impact. The hydraulic hoses are then run from the remote power unit to the dock leveler cylinder. Often the application determines the decision to go to a self-contained power unit or a remote power unit.

“Pentaflow Cylinders vs. Regular Cylinders”

Pentaflow lift cylinders are unique. In the base of the cylinder piston there is a port. This port is sealed by a ball to prevent oil from passing through. When oil is pumped into the cylinder, the cylinder extends. When the cylinder is at full extension, an actuator pushes the ball off the port which allows oil to return to the reservoir. This prevents the cylinder from dead ending. This also helps bleed any air inside of the hydraulic system. When the cylinder retracts, it siphons hydraulic oil into the top of the cylinder keeping all components of the cylinder lubricated.
