As standard Pentalift mechanical, pneumatic and hydraulic dock levelers are supplied with a 16” long hinged lip assembly.  In the majority of applications the 16” long hinged lip assembly in conjunction with 4 ½” thick laminated dock bumpers provides adequate lip length on the truck bed for safe loading and unloading. An 18” long hinged lip assembly is a very common and recommended option. The extra 2” lip length compensates for a truck that may not be backed in perfectly square t... Read More
Pentalift offers a wide range of laminated rubber loading dock bumpers. Loading dock bumpers are typically installed on the face of the building foundation wall with the top of the dock bumper(s) flush to the finished floor height. When an incoming truck backs up to the loading dock area the dock bumpers are in place to stop the truck in the proper position away from and thereby protecting the building wall.  The forces exerted by the approaching truck are high. The quality of the bumpers is... Read More
As standard all Pentalift hydraulic lift and positioning equipment and dock lifts are provided with NEMA 4 rated hand held 2 button constant pressure controls on 10’ of straight cord. The operator depresses and holds either the Up button or the Down button to change the position of the platform. See Page 4 of the brochure link to see the standard push button control. A guarded foot pedal control is available and is often ord... Read More
The primary components of a standard configuration Pentalift dock lift power unit includes an electric motor, a gear pump, an oil reservoir, an electric solenoid operated lowering valve and an electrical control system. Control buttons require constant pressure. To raise the lift the operator presses and holds the Up button on the controller. This activates the electric motor which is coupled directly to a gear pump. The rotating motor and gear pump draws hydraulic oil from the reservoir. The... Read More
For lifts to be used to accommodate loads that are rolled on to the lift platform the preferred configuration includes the use of a pit installed lift. This places the top surface of the lift platform flush with the adjacent approach surface (a floor or driveway), this results in a flat approach onto the lift platform. In some applications it is not possible or feasible to install the lift into a pit. In these applications a surface installed dock lift or lift table can be utilized.  A surfa... Read More
A Pentalift Model PS200 Dock Seal best suits door openings up to 9’ wide x 10’ high and consists of 2 120” high side pads and one 24” drop head curtain x 120” wide as standard. There are 4 designs of head curtains to choose from. The most popular model is the PS200A adjustable head curtain. The dock attendant has the ability to easily raise and lower the head curtain using a combination of ropes and pulleys. The adjustable head curtain should always be stored in the fully raised pos...

When a dock leveler is activated the deck assembly raises and the hinged lip extends. The deck assembly with the extended lip then lowers until the lip assembly makes contact with the truck bed. The dock leveler is now in the working position and the truck can be loaded or unloaded. When the lift truck drives across the dock leveler platform onto the truck bed the weight of the lift truck pushes the truck suspension down, when the lift truck drives back off the truck bed the trucks suspension...

The most common vehicle restraint installation is to lag bolt the vehicle restraint to the face of the poured concrete foundation wall. The vehicle restraint is centered on the dock leveler/overhead door width, positioned at grade level tight to the foundation wall. The vehicle restraint is then lag bolted into position; only use the anchor bolts and quantity that are specified by the vehicle restraint manufacturer. This link shows a typical installation.

As standard Vertical Storing Dock Levelers are installed into Pentalift supplied “cast in place” steel channel(s). These channels are cast in place early in the building construction schedule. One significant benefit of the cast in place channel is that it eliminates a significant amount on site welding during installation. When an order is received it is typically processed as a 2 part order. The first order is for the cast in place steel channels and the on-site arrival date is coord... Read More
The most common lift tables are hydraulically operated and use what is referred to as an Electro/Hydraulic power unit. The 5 main power unit components are electrical controls, electric motor, a hydraulic gear pump; a solenoid operated lowering valve, and a reservoir. The electrical controls take an input voltage and allocate electrical power to the different components as required to facilitate the operation of the equipment. The electrical controls also include a user interface which is typ... Read More
