As we know, air is compressible and fluids are not. Air in the hydraulic system can cause sponginess or bounce in the hydraulic cylinder until it is successfully removed.
One of the main features of a PentaFlow cylinder is that air in the system, often introduced during installation, can be easily removed to eliminate sponginess and bounce. When the lift cylinder piston reaches full extension, a horizontally positioned actuator opens the internal valve in the lift cylinder.
Once the valve ... Read More
The PentaFlow Lift Cylinder has a mechanically operated internal valve. This valve is located in the machined cartridge at the base of the chromed piston. During the lifting cycle, the internal valve is closed. When the piston reaches full extension, a horizontally positioned actuator opens the internal valve. Once the valve opens, the hydraulic oil is ported (directed) out of a fitting at the top of the lift cylinder. It then goes through a connecting hydraulic hose and back to the reservoir.

Pentalift is often asked to provide lift tables that are automated or are to be integrated into other equipment.
Pentalift has a full engineering team with professional engineers and an electrical lab where it designs and puts together all of its own control panels. These resources can be used to help design and build custom solutions for customer integration requirements.
These types of added options can be items such as the ability of the control panel to accept interlock or customer... Read More
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.

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, the industry standard, ANSI MH29.1 Safety Requirements for Industrial Scissor Lifts, requires that the lift table be equipped with guard rails on all sides These are not used for loading and unloading, unless guarded by location or other means. On sides and ends that are used for loading and unloading, the... Read More
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 lif... Read More
For many applications, the customer may wish to include some method of enclosing the scissor legs. This is to discourage personnel entry beneath the table and to prevent debris from collecting under the equipment.
The most common customer choice is a set of Accordion Bellows. Accordion Bellows are a steel, reinforced vinyl barrier which expands and contracts with the movement of the table.
Accordion Bellows work well when the travel does not exceed 10ft. Once the lift table needs to travel... Read More
In a word, many. As standard, most Dock Lift manufacturers offer a hand held push button control with an up and down button.
The push button is attached to the power unit by an electrical cord. The control cord can vary in length.Retractable coil cords are very common. They are often 5’ long retracted and stretch up to 20’ long extended, providing the operator with increased mobility.
Controls can be installed on a post on the platform or in a wall-installed control panel. The specific... Read More
They actually serve the exact same function. Some manufacturers refer to them as Elevating Docks and others refer to them as Dock Lifts.
It is the same with the common terminology, hinged lips and hinged bridge plates as well as with safety trip bars and toe sensors, to name a couple of examples. Different words, same function.
In 2012, ANSI MH29.1, the glossary of term, was revised in an attempt to standardize many of the terms used primarily for the customers benefit. Some of these terms... Read More
