6. Mechanical Installation
Installation and Adjustment
The SKC-600DC Chain-Driven Gate Opener will handle gate weighing up to 300Kg (661lb)
and up to 8m (26ft) if the proper installation procedures have been followed. The SKC-
600DC chain-driven gate operator operates by forcing a straight piece of chain through its
chain box. This length of chain is extended between two chain brackets located at opposite
ends of the gate. The motor rotates the worm and worm gear, which drive the chain and
pushes the bracket (fixed to the gate), thus moving the gate. The entire configuration is
shown in the diagram above.
Gate preparation
Be sure the gate is properly installed and slides smoothly before installing the SKC-600DC
sliding gate operator. The gate must be plumb, level, and move freely.
Conduit
In order to protect the wires, use PVC conduit for wires. Conduit must be preset into the
concrete when it is poured. Wires within the conduit shall be located or protected so that no
damage can result from contact with any rough or sharp part.
Concrete Pad
The base unit of the gate opener requires a concrete pad in order to maintain proper stability.
The concrete pad should be approximately 24" (600mm) x 12" (300mm) x 18" (460mm) deep
in order to provide for adequate operation. The pad should be 3" (70mm) above finish grade.
Be sure to locate the pad so that it will not interfere with the gate. In locations where ground
freeze is possible, extend the pad below the frost line.
