Owners Manual for the 5BH5 Hitch Mount Base for Davit Cranes
Suggestions for Safe Operation
DO the following:
Read and comply with the guidelines set forth in this Owner’s Manual. Keep
this manual, and all labels attached to the crane, readable and with the
equipment at all times. Contact Thern, Inc. for replacements.
Follow all suggestions in the “Suggestions for Safe Operation” section of the
Owner’s Manual supplied for the respective davit crane designed for use with
this hitch mounted base.
Position the hitch mounted crane base on firm ground such that the crane is
level. An uneven base may cause the boom to rotate in the direction the mast
is leaning.
Attach the hitch mounted crane base only to a 2 inch x 2 inch Class III or
better receiver hitch. The receiver hitch must be properly installed by a
qualified service technician.
Use the equipment in a clear location that is away from oncoming traffic or
other hazards.
When done working, always remove the hitch mount from the vehicle.
DO NOT do the following:
Do not lift people, or things over people. Do not walk or work under a load or
in the line of force of any load.
Do not exceed the load rating of the crane or any other component in the
system. To do so could result in failure of the equipment.
Do not install non-standard davit cranes onto the hitch mounted base without
authorization from Thern, Inc.
Do not operate or apply loads without all pins securely in place.
Do not adjust support leg positions while the crane is loaded.
Do not use the hitch mount crane base with lightweight or otherwise unstable
vehicles that may move during operation.
Do not move the vehicle with the hitch mount attached.
