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 a warning system that monitors the connection of tools to the machine quick
coupler and/or the quick coupler beneath the tiltrotator. It uses 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 QLM module mounted on the stick. It
uses sound and light warning 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.
