Pentalift introduces a dock lift hydraulic actuated bridge assist.

In some applications a longer bridge plate is required to span the gap between the truck bed and the dock lift platform. The longer the bridge plate the more the weight increases and in some cases they become too heavy to be operated manually. The dock lift hydraulic actuated bridge assist is installed on the platform and at only 10” wide minimally impedes the usable platform width. The bridge plate is stored in the vertical position, manually the bridge plate is lowered and a flow control valve assures a smooth lowering rate of speed. When the loading is completed the dock attendant simply activates a push button. The bridge plate is hydraulically actuated from the level loading position back into the vertical stored position. This feature improves safety, ergonomics and efficiency at the dock area and is available at time of dock lift sale or as an aftermarket retrofit.

What is Considered to be a High Cycle Lift Table Application?

The majority of lift tables are designed to be cycled 8 times per hour during an 8 hour shift, 5 days a week. In an application that needs more cycles than the standard amount, lift tables are recommended to be equipped with a high cycle package. A high cycle package consists of cam followers in place of leg rollers, spherical bearings in place of bushings, and often equipped with a central lubrication system. In addition to these components, high cycle lift tables are often specified with a continuous running power unit. A continuous running power unit is a power unit that keeps the motor running even when the lift table is not in use which eliminates any jog starting of the power unit resulting in pre mature wear.

We are Building a New Factory. How Do We Determine our Dock Leveler Load Capacity?

The common dynamic total load multiplier is 2.5 when calculating capacity for standard dock leveler applications. However, dynamic total load multiplier can range from 2.0 to 5.0, depending on the severity of the application and the manufacturer. Since there is no recognized industry standard, manufacturers rate their capacities differently. Some may use lower multipliers to be more competitively priced or leave the impression that their particular dock leveler is stronger than other manufacturers. Variables like fork trucks, fork truck weights, type and speed could create the need to increase the dynamic total load multiplier. Click here for an example on how to calculate.

Why Would You Project or Cantilever a Dock Leveler Pit?

Declining driveway approaches are very common at the loading dock area. Incoming vehicles are backed into position at an angle determined by the percentage of the decline. The most effective method to address this situation is to project the dock leveler pit forward. The amount of projection is determined by the percentage of the driveway decline. Projecting the dock leveler pit at the onset eliminates damage caused by vehicle impact to the building and the resultant need for aftermarket bumper extensions, longer hinged lip assemblies etc. to address this condition.

What Are The Different Operating Choices For Lift Tables?

There are 3 different operating types of lift tables. They are hydraulic, pneumatic and self leveling. All 3 styles are different but have their benefits, depending on what the application is. Hydraulic lift tables offer the widest range of features and customization regarding platform size, capacity, vertical travel, and safety features. Pneumatic lift tables are offered in an air bag design which is limited to 24” of travel. The air bag lift tables may be limited but if an airline is the only power source available to run the lift table, an air motor running a hydraulic system is available. Pneumatic lift tables are commonly used in wash down or areas where electrical sparking can cause a concern. Self leveling lift tables are mostly used for ergonomic applications. Self leveling lift tables require no power at all but do require a fork truck in order to load or unload the full pallet.
