Hydraulic Dock Leveler Optional Accessories
This page explains options that are common to Pentalift hydraulic dock levelers. For more information on any of these options or Pentalift products, contact your Pentalift representative.
Capacity is one of the most critical specifications to determine when selecting the dock leveler. It is extremely important to fully consider and properly calculate the appropriate capacity of a dock leveler needed for a specific application(s). Improper capacity selection can lead to many unwanted issues.
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. Wider dock levelers (7 ft wide) are becoming more common as trucks and trailers and their loads become wider. .
Dock levelers are typically available in 6, 8 and 10 ft (nominal) lengths. Longer lengths are utilized when the difference in height between the loading dock floor and the truck to be serviced increases. The most common length for dock levelers is 8 ft long (nominal). This length suits most applications. 6 ft long (nominal) levelers are suitable when there are minimal height differences between the dock and the truck / trailers.
There are three standard lengths of hydraulic dock leveler lips, 16”, 18", and 20". The length of dock leveler lip required depends on various factors including but not limited to: the projection of the dock bumpers, types of trailers being serviced. Generally the lip should extend 12” past the dock bumpers.
The power supply voltages available include 115 and 220 volt single phase. 230, 460 and 600 volt 3 phase. 380 3 phase 50 hertz voltage is also available. 3 phase voltages are recommended where possible to avoid any line loss issues.
Controls – Auto Return + Deck Stop Combo
This is the combination of auto return and deck stop in one panel.
Controls – Auto Return to Stored Position
This option allows the dock leveler to automatically reposition itself to the stored position on the departure of the truck trailer. It includes a selector switch should the attendant wish to turn off the feature during below dock end loading/unloading operations. Watch video
This option offers the operator the ability to stop the travel of the dock leveler deck by pushing a button. It also allows the dock leveler lip to be extended at any point in the deck travel, improving cycle times and as well as improving end loading operation..
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.
A rubber 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.
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. . [more]
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 hydraulic dock leveler. This option avoids damage to the OHD door by the hydraulic dock leveler. [more]
Vehicle Restraint Interlock
A combination control panel is provided and operates the hydraulic dock leveler and the vehicle restraint from a single panel. The hydraulic dock leveler is interlocked to the vehicle restraint. The hydraulic dock leveler cannot operate until the truck / trailer has been properly engaged by the vehicle restraint.
A roll off stop lip creates a barrier to address the concern with fork lifts falling from the loading dock. See more details by clicking on this link. [more]
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.
This oil has a lower operating temperature range than the standard oil. It is recommended for use on equipment that is subject to extremely low temperatures.
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. Click this link for more information. [more]
The easy sweep option provides a frame design that facilitates sweeping debris out of the dock leveler pit.
Shim kits are utilized to facilitate the installation of the dock leveler into a pit that is deeper than the standard pit depth.
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 as well as protects the pit edges from breaking away during fork lift roll over.
A very durable bumper with laminated bumper sections behind a plate steel bumper face which absorbs the impact of the trailer as it backs into the facility. The steel face surface facilitates truck float with minimum wear and tear to the bumper. An excellent solution for harsh loading dock environments. For more information click on this link. [more]
Lip Hinge Grease Fittings
Lip hinge grease fittings facilitate the application of grease to the dock leveler lip hinge.
Utilized to provide an upgraded level of paint finish for more demanding environments.
Additional Hose For Remote power Units
Additional hose above the standard of 24 feet can be purchased as required by the individual application.
Rather than the hydraulic power unit being installed underneath the dock leveler, the hydraulic power unit is supplied with a wall mounting bracket for installation on an adjacent interior wall. [more]
Hot dipped galvanizing is a coating that is applied to metal to provide unmatched corrosion protection and resistance. It has particular applications, advantages and specific attributes. [more]
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.
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. Free standing frames can also be used to avoid re-routing drains, gas lines, and water lines etc that are often located just under the finished floor surface.
