PRE-INSTALLATION INSTRUCTIONS
Review these requirements and procedures before installing the lift.
Consult the factory in the event that there are any questions or problems at the time of installation.
¨ The standard model dock scissor lift is suitable for use outdoors in most industrial and commercial locations.
Pre-installation notes:
· All pit and cement work, curb angles, bumper posts, conduit, and electrical installations, as well as the materials
for the same, are the responsibility of the installer or building owner.
· For a pit installation: a minimum 2” conduit installed in the pit floor or wall is recommended for allowing the hose
and wire access to the lift, and a drain should be installed.
· Five minimum 18 AWG wires (or an appropriate hard service cable) are required between the power unit’s
control enclosure and the lift’s frame. These wires, the power unit’s disconnect, and the branch circuit
overcurrent and short-circuit protection are the responsibility of the installer or building owner.
· The installation must be made so that it complies with all the regulations applicable to the dock, the lift, and their
location. The installer or building owner must verify that the supplied equipment is installed so it will be suited to
the environment in which it will be used, and it must be mounted onto, and anchored into, suitable concrete.
An architectural review of the planned installation is recommended.
· The installation of the dock lift must be performed by suitably trained personnel with access to the appropriate
equipment. The electrical aspects of the installation should be performed by an electrician.
—————————————————————————————————————
For installation you will need the following:
o A lifting boom and rigging, a fork truck with adequate fork length and capacity, or some other appropriate
hoisting means to remove the lift from the freight truck when it arrives and to set the lift into place. The models’
weights can vary from 2,800 – 6,700 pounds.
o Concrete anchors, a masonry drill, a masonry bit, hand tools, grout, and steel shims. Consult the building’s
architect or facility engineer to determine the best size and type of hardware with which to anchor the lift to the
dock approach.
o A power supply circuit and disconnect matching the motor voltage and current requirements. Refer to the labels
on the control enclosure and to the electrical section in this manual for more information.

Caution Notes:
¨ Do not work underneath the platform unless the maintenance props are installed in the frame.
¨ The dock lift must be adequately anchored into the concrete at each corner of its frame.
¨ If the supply voltage installed for the lift is different from that originally specified for the order, the connections of
the motor leads and the control transformer’s primary wires must be changed. Consult the electrical diagrams
in this manual.
¨ Modifications or additions to the lift without prior manufacturer’s authorization may void the lift’s warranty (see
ANSI MH29.1, Safety Requirements for Scissor Lifts, section 12.6). The addition of ancillary equipment to the
platform may necessitate that its load capacity be reduced.
