This page explains options that are common to Pentalift air powered dock levelers. For more information on any of these options or Pentalift products, contact your Pentalift representative.

Foam Insulation

The primary purpose of foam insulation is to reduce condensation on the dock leveler deck surface due to significant temperature differences from inside to outside. This condensation can cause traction for fork lifts and dock workers to be compromised, a safety concern.  Foam is also used as an energy saving option limiting the transfer of conditioned air temperature between inside the facility and outside.

 

 

Two Position Mechanical Fall safe

Air powered fallsafe legs limit the dock levelers ability to travel below level. They come with a manual means of deactivation for instances where the dock leveler is to be utilized below level.

Weather Seal

A rubber (shown) or brush weather seal reduces the passing of outside elements into the facility by sealing the edges of the dock leveler deck against the dock pit.

Free Standing Frame

If floor space is at a premium a free standing frame assembly can be used to install a dock leveler on the exterior of the building.

Lip Hinge Grease Fittings

Lip hinge grease fittings facilitate the application of grease to the dock leveler lip hinge.

Curb Angle Assembly

Steel angle iron with tab anchors welded along it are provided and embed into the edges of the dock leveler pit. The curb angle provides a metal edge to weld the dock leveler to during installation...

Shim Kits

Shim kits are utilized to facilitate the installation of the dock leveler into a pit that is deeper than the standard pit depth.

Installation – Pour In

This option reduces the overall costs in new installations. Concrete can be poured around the dock leveler during the floor pour of the building. All installation welding is completed at the factory.

Interlock Options – inflatable dock seal

A combination control panel is provided. A single control panel operates the inflatable dock seal or shelter, hydraulic dock leveler and / or vehicle restraint. The inflatable dock seal or shelter are connected to only activate when the dock leveler or vehicle restraint are in a predetermined state of use.

Tapered Lip

The dock leveler lip is tapered narrower on the end that is positioned on the truck. This option was required more in the past when 7ft wide dock levelers were to be utilized and when trailers were generally narrower than today. Tapering of the lip reduces the effective width of the dock leveler and is not required in most cases.

 

Vehicle Restraint Interlock

A combination control panel is provided and operates the Air/hydraulic dock leveler and the vehicle restraint from a single panel. The hydraulic dock leveler is interlocked to the vehicle restraint. The air/hydraulic dock leveler cannot operate until the truck / trailer has been properly engaged by the vehicle restraint.

 

Interlock Options – Overhead door kit

A limit switch and a mechanism for activating the limit switch by the overhead door is provided. This interlock prevents the dock leveler from being activated if and when the overhead door is positioned in the operating path of the air/hydraulic dock leveler. This option avoids damage to the OHD door by the air/hydraulic dock leveler.

Weatherseal – Brush

Seals the edges of the dock leveler deck to prevent and reduce energy loss. In addition to reducing energy loss brush weather seal reduces the entry of vermin into the facility. Brush weather seal typically has a longer life then the rubber weather seal. Can be installed on the sides and / or rear of the dock leveler. Facilitates energy savings and vermin entry control.

Lip Length

There are three standard lengths of air/hydraulic powered dock leveler lips, 16”, 18", and 20". Â The length of dock leveler lip required depends on various factors including but not limited to:

Dock Leveler Length

Dock levelers are available in 6 and 8 ft lengths. Longer lengths are utilized when the difference in height between the loading dock floor and the truck to be serviced increases.

Dock Leveler Width

Dock levelers are typically available in 6, 6.5 and 7 ft wide (nominal) sizing. The width of the dock leveler is dependent on the width of trucks being loaded / unloaded and configuration of loads.

Dock Leveler Capacity – Understanding Loading Dock Capacity

Capacity is one of the most critical specifications to determine when selecting the dock leveler. It is extremely important to fully consider and properly
