Motor Holding Brake
A motor holding braking system engages and holds the vertical axis in place in the event of a power outage or
when the Run-Stop button is pressed.
Overload Capacity Protection
Protects the equipment and prevents the operator from lifting or moving more weight than the system is rated
for. If the load weight exceeds the programmed capacity, the hoist will not lift any further until the excess
load is removed. Downward motion is permitted when overloaded to allow the user to safely set the weight
back down on a stable surface.
Run-Stop Push Button
If an operator needs to stop motion immediately, the operator pushes the Run-Stop button. The
system will not function until it is reset. To reset the system from the Run-Stop condition, the operator turns
the button clockwise to release it from the depressed position. All virtual limits and programs remain intact.
Safety Drop Stop (SDS) Chain
All Standard units have a Safety Drop Stop (SDS) chain included. The SDS Chain moves up and down the
vertical axis with the load chain. It provides load stabilization in the event of a catastrophic load chain
failure. This unique feature has a US Patent NO. 10,099,904 awarded as of 2018.
