3. Design and function
3.1. General
The engcon machine coupler is mounted on the excavator's stick. The
machine coupler renders tool attachment and detachment more efficient.
DANGER
Do not exceed tipping load limits.
The weight of the product and the
increased reach may impair stability.
Risk of personal injury and damage to
property.
3.2. Q-Safe
Q-safe is one of the world's safest quick couplers/machine couplers.
It has a warning system that monitors the connection of tools to the
machine quick coupler and/or the quick coupler beneath the tiltrotator. It
has a double mechanical lock to prevent the tool coming loose from the
coupler, even if some part of the locking system should fail. The alarm
outputs are connected to a siren and a beacon that are mounted on the
stick. They alarm by means of sound and light signals when a tool is
incorrectly connected, as the primary safety purpose of the quick coupler
is to protect personnel nearby. The operator must inform personnel
concerned what the alarms mean.
WARNING
Stop work immediately and begin
troubleshooting if the system warns
of a faulty tool connection during
operation. Risk of personal injury and
damage to property.
CAUTION
Use hearing protection when in close
proximity to or operating the Q-Safe
machine coupler when connected.
Risk of hearing loss.
