August 19, 2016, 12:58 pm - The majority of dock lift manufacturers use lift cylinders that “dead end” when the lift cylinder is fully extended. “Dead ending” the lift cylinder puts stress into the lift cylinder components. The power unit’s pressure relief valve must open and mechanical stops are required. A PentaFlow Lift Cylinder has an internal mechanical valve that opens automatically every time the cylinder reaches full extension. The hydraulic oil is ported directly back to the reservoir.

August 5, 2016, 9:58 am - This question is asked often. A 1hp, 3hp; 5hp etc. power unit will all raise a dock lift of any capacity. The reason for increasing the horsepower rating is related to the lifting speed. As the lifting capacity gets increased, additional lift cylinders are required to lift the extra weight. To fill the lift cylinders in a time that is acceptable to raise the dock lift, the volume of oil being pumped to the lift cylinders is increased. This requires a larger volume pump. To operate the larger volume pump, a higher horsepower rated motor is required. Contact a Pentalift Sales Representative for more information.
July 15, 2016, 1:48 pm - Pentalift lift tables can have additional options included that will permit use as a work platform , or for riders to travel with the load. When there will be personnel riding on the table it must be equipped with guard rails on all sides that are not used for loading and unloading, and gates or chains for any side used for loading and unloading. Pentalift also recommends moving to checker plate on platform where there will be riders. If preferred, Pentalift can offer an anti-slip grit that is imbedded in the paint, but this grit will wear with traffic. Any tables where there are riders must have constant pressure controls…press and release controls are not permitted when there are riders. Finally, any application where there will personnel on or around the table must be reviewed for any potential pinch or shear points. Contact your Pentalift Sales Representative for more information.
July 7, 2016, 2:28 pm - Only if you are using a lift truck on your dock lift would you require an Automatic Hydraulic Roll-Off-Stop. When the dock lift is in the lowered, closed position, the roll-off-stop is flat. The lift truck drives across the roll-off-stop onto the platform. When the "up" button is activated, the roll-off-stop is powered into the vertical position before the dock lift begins to rise. When the dock lift is in the raised position, the lift truck drives onto the delivery truck. When the lift truck backs out of the truck, the roll-off-stop prevents the lift truck from accidentally driving off the dock lift and falling to the lower level.
