Hazards Which May Be Caused By The Machine - DEMAG DC-Com 1 Operating Instructions Manual

The manufacturer is not liable for unauthorized structural modifications which have not been agreed with him. This
includes incorrect connection of the machine to devices or equipment that do not belong to our scope of delivery, or
the installation or use of accessories, equipment or sub-assemblies of other manufacturers that are not approved
by the manufacturer.
Depending on the type and scope of the machine, an inspection must be carried out by an expert engineer before
handing it over to the owner.
DC-Com chain hoist are designed for operation at temperatures of -20 °C up to +40 °C. At extreme temperatures
and in aggressive atmophere or under conditions deviating from the section "Operating conditions", special meas‐
ures must be taken by the owner in agreement with Demag.
Use of the control pendant
Powered lifting and lowering and, if applicable, cross-travel and long-travel motions are controlled by means of the
corresponding control elements on the control unit. The slow speeds are intended for attaching the load, lifting it free
and depositing it. Loads can be precisely positioned at slow speeds.
Short transport times can be achieved at higher speeds. They are suitable for travelling without a load or with a
safely suspended load if no hazard can be caused by the faster motion sequences.
Inching must be avoided, as it causes increased wear and load sway.

Hazards which may be caused by the machine

The machine has been subject to a risk assessment. The design and execution based on this analysis corresponds
to state-of-the-art engineering principles. Nevertheless there are residual risks!
The machine is operated at high electrical voltage.
DANGER
Live components
Danger to life and limb.
Electrical energy may cause serious injuries. If the insulation or individual components are damaged, there is
danger to life caused by electrical current.
– Before carrying out maintenance, cleaning or repair work, switch off the machine and secure against restarting.
– Switch off the power supply when carrying out any work on the electrical installation. Check the components
to be replaced for being de-energized.
– Do not remove safety equipment or render it inoperative by modifications.
WARNING
Crushing hazard
The lifting or lowering of loads may cause crushing hazards for parts of the body.
When lifting or lowering loads, it must be ensured that no persons are in the immediate danger zone.
WARNING
Suspended load! Falling parts!
There is danger to life and limb, when suspended loads fall down.
Persons must keep out of the danger zone.
– Keep a sufficient safety distance.
– Do not walk under the suspended load.
Certain work and practices are prohibited when using the machine as they may involve danger to life and limb and
result in lasting damage to the machine. Please note the safety instructions in the chapters:
