Lifting Hook - Hitachi 120-3 class Operator's Manual

LIFTING HOOK

Handling suspended loads
This machine was specifically designed for excavation/load-
ing application. Handling suspended loads, as a completion
of excavation/loading application, is admitted on condition
that the machine is equipped with the specific device sup-
plied by HITACHI Construction Machinery on request. For
handling suspended loads strictly follow the national laws
on this subject, the rules indicated below.
WARNING: Load holding and lowering pilot operated
valves located on cylinders, overload warning device,
the lifting capacity chart in the cabin and hook on the
"A" link are SAFETY DEVICES being part of the version
for suspended load handling. If one of these devices
is missing or damaged, the machine cannot be used
for handling suspended loads.
WARNING: Before handling suspended loads, check
that valves are not damaged or unusually noisy. If any
defect is discovered, contact your dealer and do not
use the machine for handling suspended loads. Lift-
ing devices (hooks, chains, etc) must be undamaged
and not worn. Check before use. Follow the current
laws to check these devices. (they are not supplied
with the machine)
WARNING: To avoid any possible accident, do not
exceed the machine's rated lifting capacity. If the
machine is not on level ground, lifting capacity is
reduced. Set the engine power suitable for the re-
quired hydraulic power. Estimate (if not known) the
weight of the object to handle and compare with the
data on the lifting chart in the cabin. Do not lift loads
whose weight exceeds the maximum load on the
chart. Before starting lifting operations, press switch
(1) to engage the overload warning device sensor.
When reaching the limit load the sensor activates an
acoustic device. Fix the load by the special hook (2)
on the "A" link , by using coupling devices and chains
suitable for the load to lift.
