ULTRAHOOK UHR40 VEHICLE RESTRAINT
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.

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).
