November 30, 2015, 4:13 pm - The majority of dock lift control stations are electrically operated to both raise and lower the platform, so if there is a power failure the control buttons will not operate the lift table. If the dock lift is in the elevated position when the power failure occurs you will not be able to lower the dock lift unless the power unit is equipped with an optional manual lowering valve. The manual lowering valve would be located on the power unit, and when opened, the hydraulic oil in the lift cylinders will be directed back to the reservoir. This will permit the table to lower.

All requests for lift tables can be classified into two general categories at the most basic level...either requests that fall within the characteristics of Pentalift's standard Pre-Engineered Products, or requests for unique and custom pieces of equipment. Generally there is no requirement for an approval drawing when a customer is seeking a piece of equipment from Pentalift's Pre-Engineered Products. When a custom piece of equipment is required, then an approval drawing will need to be reviewed and signed by the customer before proceeding.
The approval drawing is a visual representation of specified equipment that is generated by Pentalift Engineering after quote and design stages are complete, and once there is a commitment to proceed to order. The drawings will reflect all of characteristics for the custom equipment that were included on the quote. Approval drawings will always include one drawing of the equipment itself, but there will often be addition drawings to illustrate the associated pit, or the electrical schematic, or the hydraulic schematic, etc. Depending on the significance and complexity of the customization, generating approval drawings can take between 2 and 5 business days on average. Once the drawings are generated, they will be sent to the customer for review and approval before the order will be formally entered in production schedule.

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.
