Safety Information
2.7 Applications with Lifting Gear
General information • Craning applications are procedures involving raising, transporting and lowering loads
with the help of slings and load-securing devices (for example, ropes and tracks). In
doing so, the help of persons is necessary for securing and detaching the load. This
applies, for example, to lifting and lowering pipes, shaft rings or containers.
• The excavator may be used for applications with lifting gear ONLY if the prescribed
safety devices are in place and functional.
Safety criteria • When used for craning applications, the machine must meet the following criteria:
• Proper equipment for slinging and securing the load
• Proper lift capacity per tables in this Operator’s Manual
• In addition, a safe load indicator is required for machines bearing loads of over 1000 kg
(2205 lbs.) or an overturning moment of over 40000 Nm (29,477 ft.lbs.).
Conditions for safe operation • Secure the load to prevent it from falling or slipping. Install an OSHA-approved load
hook after removing the bucket or other approved attachment to provide a secure
attachment point for the lifting sling, track, or cable.
• Have loads fastened, and crane operators instructed, by a qualified person competent
in raning operation and standard hand signals. The person giving instructions to the
operator must be within sight of the operator during load attachment and load
disconnection.
• The load shall be kept as close to the surface as practical to accomplish the craning
operation. The operator shall gently move the controls and machine to avoid swing or
oscillating motion of the load. A tether line is recommended to dampen the tendency of
the load to swing or oscillate during the craning operation.
• Machine travel with a raised load must be done very carefully on a level surface moving very
slowly to avoid sudden motion that can cause swinging or oscillating motion of the load.
• The person(s) attaching the load to the excavator shall approach only if the operator is
in visual contact with them. No one shall approach the machine or attempt to attach the
load until the excavator has stopped and the operator has signaled for the attachment.
2.8 Attachments
General information regarding
attachments • Prior to traveling remove all attachments which cannot be secured in compliance with
the legal regulations of your country.
• The machine operating characteristics including steering vary with different option
attachments and counter weights. The operator shall be familiar with the variations and
act accordingly.
• Use only approved attachments and connecting hardware.
• Attach and remove attachments carefully to avoid damage and potential injury.
• Attach and remove attachments carefully to avoid damage and potential injury.
• Confirm that the attachment has been properly and securely attached to the machine
according to the instructions. Before using the attachment, the operator shall confirm
that the attachment performs correctly in response to control actuation.
• Do not attach the attachment with the engine running and the machine moving.
• Before putting the machine/attachment into operation (startup/moving), make sure that
no one in the immediate vicinity will be at risk.
• Before leaving the seat, always secure the machine against unintentional movement
and unauthorized use. Lower the attachments to the ground.
• Mount the attachments only if the engine and the drive have been stopped.
• Especially when driving or working with machines equipped with a quickhitch for the
attachments, make sure the attachment is securely locked in the quickhitch. The lock
pin must be visible on either side of the bores on the attachment. Check before starting
work.
