OWNER RESPONSIBILITY
The Owner's Responsibilities include the following:
6.3.1 The owner should recognize inherent danger of the interface between dock and transport vehicle. The owner shall,
therefore, train and instruct loading dock operating personnel in the proper use of restraining devices in accordance with
information provided in Section 6.1.2.
6.3.2 Nameplates, cautions, instructions, posted warnings and communication lights shall not be obscured from the view of
loading dock operating personnel or maintenance personnel for whom such warnings are intended (also see 6.1.3 and 6.3.5).
6.3.3 Manufacturer’s recommended periodic maintenance and inspection procedures in eff ect at date of shipment shall be
followed, and written records of the performance of these procedures should be kept.
6.3.4 Restraining devices that are structurally damaged shall be removed from service, inspected by the manufacturer’s
authorized representative, and repaired as needed before being placed back in service.
6.3.5 The manufacturer shall supply replacement nameplates, communication lights, caution or instructional labels, and
operating and maintenance manuals upon request of the owner. The owner shall see that all nameplates, communication lights,
and caution and instruction markings or labels, are in place and legible and that the appropriate operating and maintenance
manuals are provided to users (see also 6.1.3 and 6.3.2).
6.3.6 Modifi cations or alterations of restraining devices shall be made only with written permission of the original manufacturer.
These changes shall be in conformance with all applicable provisions of this standard and shall be at least as safe as the
equipment was before modifi cation. These changes shall also satisfy all safety recommendations of the original equipment
manufacturer for the particular application of the restraint.
6.3.7 When industrial vehicles are driven on or off a transport vehicle during loading or unloading operation, the parking brakes
on the transport vehicle shall be applied and wheel chocks or another vehicle restraint that provides equal or better protection
shall be engaged. Also, whenever possible air-ride suspension systems should have the air exhausted prior to performing said
loading or unloading operations.
6.3.8 When a vehicle restraint is unable to properly engage a transport vehicle, the user shall activate the applicable
communication if so included, or provide an alternate method to address a “not restrained vehicle condition” to alert and or protect
the loading dock operating personnel.
6.3.9 When selecting a restraining device, it is important to consider not only present requirements but also future plans or
adverse environments.
6.3.10 The restraint should never be used in a manner not intended by its design. It must also be compatible with the loading
dock equipment and other conditions relating to the loading dock area.
NOTE: The MH30 Committee recognizes the devices intended to secure a transport vehicle to a loading dock by mechanical
means. The NHTSA Standard 49CFR ch.V 571.223 specifi es the strength of the rear impact guard and 49 CFR Ch.V 571.224
specifi es the size and locations of the rear impact guard. It is, therefore, recommended that users of such positive restraint
devices review:
• The means of attachment to the transport vehicle
• The strength of the overall connection
• The proper coordination of the actuation of devices with any signaling system used
• The need to use wheel chocks
Unless specifi cally agreed to in writing by Pentalift Equipment Corporation at the time the
equipment is ordered and prior to the equipment’s manufacture, this equipment is sold as

INSTALLATION INSTRUCTIONS
1. _ Ensure pit construction has suffi cient strength to meet the draw pull forces which will be applied. (See Figure
6: Concrete Loading Diagram for Lagged in Models on page 10.) Further, ensure the dock leveler pit, as well
as the restraint pit, meet the pit diagram dimensions as provided by the manufacturer, complete with appropriate
conduit(s).
2. _ Ensure you have all necessary components as shipped with the unit.
• Ultrahook
• Brush Weather Seal Assemblies
-brush weather seal carrier x 36” long - 2 pieces
-face plates 12 Ga x 15-5/8” x 36” long - 2 pieces
• Sign Package – 4 pieces
• Electrical Control Panel (common control panel may be shipped with the dock leveler)
• Power Unit
• Outside signal lights (may be shipped with the dock leveler)
3. _ Clean pit of all debris.
4. _ Mark the center line of the pit fl oor from front to back (see Figure 4: Position the Ultrahook on page 8).
5. _ Mark the center line of the Ultrahook frame at the front and back (see Figure 4: Position the Ultrahook on
page 8).
6. _Hoist the Ultrahook by slinging through the lifting point at the cylinder pivot and the hook(See Figure 3: Slinging
Unit on page 8.)
7. _ Position the Ultrahook into the pit, keeping the front of the frame fl ush with the outside surface of the
foundation wall. Align centerlines (front and rear) of the Ultrahook with centerlines of the pit (see Figure 4: Position
the Ultrahook on page 8).
8. _ Lag the frame to the pit fl oor using 3/4” lag bolts with a minimum shear value of 10,000 lb and minimum
tension value of 10,000 lb. (see Figure 6: Concrete Loading Diagram for Lagged in Models on page 10)
9. _ Install the dock leveler following the manufacturer’s installation instructions. Raise the dock leveler and
secure it in place using the manufacturers maintenance procedure (see the dock leveler Owners Manual). Then
disconnect all power supply.
10. _ Mount power unit and the signal junction box (by others) in the pit (See Figure 8: Power Unit and Junction
Box). Ensure that these components are mounted in a location which ensures they will not make contact with the
dock leveler but are close enough to the vehicle restraint to allow the pre-wired proximity and pressure switches to
reach the junction box. It is recommended to locate the components toward the rear of the dock leveler pit. This
accommodates the fact that the dock leveler deck assembly will move below fl oor level during operation. Note:
The control panel and the power unit are to be located in an area that is clean, dry, and free from exposure to
liquids and excessive debris and external weather.
11. _ Mount the outside light approximately 90” from the center of the light to fi nished driveway level (See Figure 7:
Mount Outside Light and Signs on page 11).
12. _ Mount the mirror image caution sign above the outside light; the normal vision caution sign below the outside
light and the “Warning Stand Clear...” sign centered vertically directly to the right of the Ultrahook (See Figure 7:
Mount Outside Light and Signs on page 11).
13. _ Install the control panel in a location that ensures an unobstructed view at all times. The installation location
must ensure the complete legibility of the operating instructions during the operation of all loading dock equipment,
including the fork lifts.
14. _ Connect all required electrical connections as per appropriate wiring diagram located inside the electrical control
panel (See ELECTRICAL INSTALLATION INSTRUCTIONS on page 12).

turn the ULTRAHOOK switch to DISENGAGE. Check the indicator lights located on the front face of the PLC. The
following indicators must be lit:
- PWR(Red LED) - 0C “Hook Fully Retracted”(Green LED)
- RUN(Green LED) - 0F “Maintenance Mode”(Green LED)
- 08 “Hook Fully Extended”(Green LED) - 47 “Outside Green Light”(Green LED)
- 09 “4” from Dock Face”(Green LED) - 41 “Inside Red Light)(Green LED)
7. _ If these indicators are not lit as per step (6), check all connections before proceeding to ADJUSTMENTS AND
TESTING on page 14.
8. _ Once the electrical connections are completed and the dock leveler is installed, cycle the restraint several times
to ensure there is suffi cient clearance, the unit is positioned properly and that all proximity switches, the tilt spring and
hard stops are adjusted correctly.

9. _ Trim the height of the brush weather seal assemblies so that they overlap the 2” step at the bottom front of the
restraint by 1” and the dock leveler front angle by approximately 1”. Ensure that the two halves of the brush weather
seal assemblies meet at the center of the pit opening. Fasten brush weather seal assemblies to the dock face using
1/4 concrete screws of the type that are removable and re-useable (see Figure 5: Mounting the Brush Weather Seal
on page 9). Note: If the trimming operation removes some bolt holes and fasteners, then the cover plate and
brush weather seal carrier may need to be re-drilled. This will depend on how much material is removed from the
brush weather seal assemblies to suit restraint vertical opening and dock height.
10. _ Confi rm that all steps of the installation instructions have been completed. Fill out the following information.
