April 7, 2017, 3:28 pm - Dock levelers are manufactured with 3 operating styles. They are mechanical (spring), pneumatic (air), and hydraulic (oil). Mechanical is initially the least expensive, however they require an element of physical effort to both raise and lower the platform. From an ergonomic and safety perspective, hydraulic dock levelers provide the best performance. Contact your Pentalift Sales Representative for more information.
August 11, 2016, 1:19 pm - Pentalift pre-engineered (standard price list) lift tables are available with capacities ranging from 500 lbs. to 40,000 lbs. Pentalift also offers a high capacity series of lift tables with capacities ranging up to 120,000 lbs.Contact a Pentalift Sales Representative for more information.
May 18, 2016, 4:48 pm - Mechanical Dock Levelers use a series of springs and levers to raise the platform and extend the lip assembly. The Mechanical Dock Leveler is then “walked down” into position on the delivery truck bed.Air Powered Dock Levelers, though structurally the same, use a push button control station to operate a 115/1/60 blower, which inflates an air bladder to raise the platform. A mechanical assembly operates the hinged lip. Once the lip is actuated and fully extended, the dock attendant releases the control button and the dock leveler automatically lowers into position on the truck bed. Mechanical Dock Levelers are more cost effective at the time of purchase.Air Powered Dock Levelers cost more to purchase but because they have fewer mechanical components, require less maintenance and are more ergonomically accepted.

February 17, 2016, 3:31 pm - Lift tables can be ordered with many different surface finishes. The selected finish is based on the application requirements. If a lift table is used in an industrial setting for positioning or in an ergonomic application then standard enamel paint finish is usually acceptable. Upgrading to epoxy paint finish provides optimum protection against abrasion, corrosive fluids, extreme temperature and impact. Pentalift's standard paint color is gray, however you can upgrade to any desired custom color. Lift tables can also be galvanized for use in wash down applications or even manufactured from 100% stainless steel for use in the “direct contact” food processing industry. When the overall design parameters have been finalized then the Sales Representative can suggest the most suitable finish for the application.

There are often lift table applications where it is impossible to permit electricity. Pentalift offers several options to overcome this situation. The first would be to look at the Pentaloader, an exclusive self-leveling Pentalift product that uses a spring cam arrangement to automatically present the load at an ergonomic height without using any power source. This table does not require any power unit of any kind, and is the only really durable, industrial strength self-leveler available in the marketplace. The Pentaloader is available in (4) different configurations, which can handle loads anywhere from 600lbs to 4500lbs. The spring tension can be adjusted without the use of any tools, by simply adding or removing spring locking pins from the system.
Another option would be to look at using a pneumatic table. There are two ways that Pentalift offers air tables. The first would be the Pro Air Series, which uses air bag technology to actuate the table. The other possibility would be to use a normal lift table with hydraulic cylinders, but then drive the cylinders using an air motor. Air bag technology is quieter and less expensive, but has limited size and vertical travel capabilities. Air motors provide much more flexibility when it comes to size and vertical travel, but are louder and are more expensive. Contact your Pentalift Sales Representative for more information.
