Attachment - Hitachi ZAXIS 450LC-3 Operator's Manual

ATTACHMENT

Allowable Weight Limits of Installed Attachment
• When an attachment other than the standard bucket
is installed on the machine, the machine stability will
be different. If a heavy attachment is used, not only will
controllability be affected but also machine stability will be
reduced, possibly causing safety hazard.
• Before installing attachments such as hydraulic breaker,
crusher (concrete crusher), or pulverizer, take machine
controllability into account when selecting the weight of
the attachment by referring to the table below.

• Breaker operation speed is faster than crusher operation so
that the recommended breaker max. weights are reduced
more than those of the crushers.
• The weight is not the only factor to be considered when
selecting a breaker. Select proper manufacturers' breaker
models while referring to the table on the next page.
• Avoid installing an attachment with a long overall length.
Damage to the front attachment may result.
• When an attachment of the max. weight is installed, always
operate the attachment over the front or rear side of the
machine. In addition, avoid operating the attachment at the
maximum reach.
• Crushers are heavier than breakers. Slowly move the control
lever when operating a crusher.
