July 10, 2015, 1:42 pm - Why do most loading dock equipment manufacturers offer both a pit model and a surface model of dock lifts? The majority of dock lifts are manufactured to suit a recessed pit installation. In some applications the site is unable to accommodate a recessed pit, perhaps due underground services and the difficulty and/or expense associated with rerouting them. In this application, temporary applications, or perhaps just for flexibility in the future, a surface installed dock lift equipped with an approach ramp can be the best solution. Pit model dock lifts are available in the most platform sizes, capacity’s and with many more options available. There is a definite requirement for both models of dock lifts; the application generally dictates the right selection. Contact your Pentalift Sales Representative for more information.

Many applications will require that your lift table be installed into a concrete pit.
The first thing to consider is your pit's overall dimensions. Beginning with the width and length, you want to leave a 1" gap around the perimeter of the platform, between the edge of the deck and edge of the pit wall. As a starting point, therefore, your overall pit width and length will be the platform width + 2" and the platform length + 2". This is for a lift table with no hinged bridges. Once you add a manually operated hinged bridge, you need to provide additional clearance between the edge of the platform and the edge of the pit wall, to allow space for the hinge spools, etc. This additional gap requirement increases further if you are utilizing a hydraulic hinged bridge, to permit space for the cylinder to extend the bridge. Consult your Pentalift Sales Representative when employing hydraulic bridges.
The next consideration is the depth of the pit. You want to cut your pit to the fully lowered height of the lift table, plus an additional 1/4", to ensure that the table does not project out of the pit. It is much better to have to shim a table slightly to bring it up to floor height then it is to try to rework a pit because the equipment has a slight projection. Once you have the pit dimensions finalized, you will need to consider the configuration of the power unit and the type of options on the table to determine any conduit requirements. Please contact your Pentalift Sales Representative if you have any questions about requirements for pit installation of lift tables.
June 22, 2015, 8:59 am - What does dock leveler deck cant mean? Deck cant means that the dock leveler platform can tilt or flex up to 4” per side. If the truck and dock leveler are both level then the deck cant feature is not required. However if the incoming truck is up to 4” higher on one side than the other, this could be caused by an uneven approach, snow/ice build-up on one side of the drive etc. then the deck cant becomes a very important feature. As the dock leveler is cycled the platform lowers to the truck bed and the hinged lip assembly makes contact with the truck bed. Deck cant provides torsional flex allowing the lip to conform or laterally flex to the uneven truck bed. The lip resting flat on the truck bed minimizes and damage to the material handling equipment, product and impact to the operator. Contact your Pentalift Sales Representative for more information.

Pentalift UpEnders are engineered and designed for applications where a freestanding piece of equipment is required to safely reorient and provide 90° tilt for heavy and awkward loads. Pentalift offers several pre-engineered UpEnder models, while also providing solutions for larger and very heavy custom UpEnding applications. Here is a link to a case study where Pentalift built a custom 60,000lb UpEnder to suit a customer’s application. Common options include: v-groove on one plane, used to help stabilize cylindrical loads; limit switches to restrict tilt to less than 90°; tie down locations installed on deck, to facilitate customer securing of loads; etc. Contact your Pentalift Sales Representative for more information.

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.
