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.
June 8, 2015, 10:15 am - Vehicle restraints were first introduced to increase safety at the loading dock approximately 35 years ago. The most common safety device has always been the wheel chock for the truck. Wheel chocks are like a wedge, and once the truck is backed into position, the chocks are manually positioned in front of the back wheels to the stop the truck from rolling forward while it is being loaded. Often these chocks go missing, or can can slip on the snow and ice during winter weather. Since they are usually attached to the foundation or the building at the overhead door, vehicle restraints combined with communication light packages, are much more reliable and effective than wheel chocks. When the truck is backed into position the dock attendant activates the vehicle restraint. The vehicle restraint hooks onto the truck’s rear impact guard and locks the truck into position.
Vehicle restraints are not yet mandatory, but more and more companies are specifying vehicle restraints for all of their new buildings as well as adding them to their existing facilities. The loading dock area is often referred to as the most dangerous part of any manufacturing or distribution center, so to increase safety more and more vehicle restraints are being installed.
