Attachment quick coupler, U14-U52
WARNING
Risk of crushing.
Falling attachments could result in severe injury or
death.
Make sure the attachment bracket is properly
locked before starting work.
WARNING
Risk of crushing.
An unsecured attachment could fall and cause
serious injury or death.
Always ensure the attachment is properly secured
by pressing the front part of the attachment to the
ground until the machine is slightly lifted.
The attachment quick coupler is equipped with a
double-acting hydraulic cylinder. The hook for
gripping the attachment is fitted to its piston rod.
The hydraulic system's pressure acts on the lock
cylinder's piston, locking the attachment in place
against the rear bucket pin. This means that the
hook adjusts itself and provides gap-free locking.
When checking from the cab if the attachment quick
coupler is locked or unlocked, slowly curl out the
bucket/attachment and dipper arm.
By means of the lifting eye, the machine can be
used for lifting operations. Since the lifting eye is
located on the attachment quick coupler, it can be
used without a bucket. This improves visibility for
the operator and increases the maximum
permissible load.
NOTE!
