5.5 Crane operations
5.5.1 General
Crane operations are the hoisting, transporting and lowering of loads with the aid of a fixing
device (rope, chain, etc.), whereby the assistance of personnel is required to attach and release
the load.
5.5.2 Safety devices
The excavator may only be used for crane
operations when the prescribed safety devices are
present:
- Secure attachment of loading implements
- Table of carrying capacity, see section 5.5.5
- Overload warning device and a hose-rupture
safety valve if the permissible carrying capacity
exceeds 1,000kg.
The load limit is marked on the overload warning
device (7/6)
Danger starting from: 90 bar
5.5.3 Attachment of loads
Note
Loads must be attached in such a way that they cannot slip or fall out.
Possible forms of attachment
• Load hook attached instead of a bucket, etc.
• Hook with safety net welded onto the bucket rod (not possible in the case of quick-mounting
buckets with ejectors).
A suitable, appropriately sized loading implement must be employed for picking up the material
to be lifted.
Always wear protective gloves when working with loading implements.
5.5.4 Attachment and carrying of loads
Attention
Personnel guiding the machine and attaching loads must remain only in the machine
operator’s field of vision.
Personnel attaching loads may only approach the boom from the side and with the machine
operator’s permission. The machine operator may only give his permission if the machine is
standing still and the work equipment is not in motion.
The machine operator must carry loads as close to the ground as possible and prevent them
from swinging.
Machines may only travel with an attached load if the path of travel is fairly even.
