DEMAG DC-Com 1, Руководство по эксплуатации

Страница: 13 / 116

Depending on the type and scope of the machine, it may be necessary to have an inspection carried out by an
expert engineer before it is handed over to the owner.
DC chain hoists are designed for operation at temperatures from - 20 °C to + 45 °C. At extreme temperatures and
in aggressive atmospheres or conditions differing from those specified in the "Operating conditions" section, the
owner must implement special measures after consulting 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 (flick switching) must be avoided, as it causes increased wear and load sway.
2.4 Hazards that can be caused by the machine
The machine has been subjected to a risk analysis. The design and execution based on this analysis corresponds
to state-of-the-art engineering principles. However, residual risks remain.
DANGER
Live components
Danger to life and limb.
Electric energy may cause very severe injuries. Danger of death caused by electric current if the insulation or
individual components are damaged.
–
Switch the machine off and secure it against restoration of the power supply before any maintenance,
cleaning or repair work is carried out.
– Switch the power supply off before any work is carried out on the electric equipment. Check to ensure that
the components to be replaced are de-energised.
– Do not remove any safety equipment or render it inoperative by modifications.
WARNING
Crushing hazard
Body parts can be crushed when loads are lifted or lowered.
Ensure that nobody is present in the immediate danger zone when loads are lifted or lowered.
WARNING
Suspended load. Falling parts.
Danger to life and limb if lifted loads are dropped.
Keep out of the danger zone at all times
–
Keep a sufficient safety distance.
– Never step under a 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. Observe the safety instructions in the sections:
