Chain hoists Chain hoists are systems used for lifting and moving loads, such as cranes, crabs and travelling hoist units, rail systems.
These symbols are used throughout the operating instructions in order to visually indicate hazard warnings. Saftey at work symbol This symbol appears in the operating instructions next to all instructions relating to safety at work wherever a potential danger to life and limb exists. Follow these instructions at all times and be particularly careful and cautious. Pass on safety instructions to all persons entrusted with working on the chain hoist. In addition to the safety instructions, observe all general safety regulations at all times.
Warning against electrical hazards Contact with live parts can result in immediate death. Protective covers e. Before opening, all relevant operating, control, feed or other voltages must be disconnected. Warning against suspended load Any person remaining in this danger zone may suffer serious injury or death. This applies in particular to non-positive locked load handling attachments e.
In each case the special safety and operating instructions contained in the operating instructions for the load handling attachment in question must be complied with.. Operating hazard for the installation This symbol in the operating instructions indicates all warnings which, if not complied with, may result in damage to the chain hoist or the load.
Electric chain hoists are only intended for lifting and moving loads and may be used as stationary or travelling units. Electric chain hoists may only be operated when in perfect working order by trained personnel in accordance with the relevant safety and accident prevention regulations. This also includes compliance with operating and maintenance conditions specified in the operating instructions.
Chain hoists are industrial equipment designed to be used with a rated voltage of up to V for alternating current. Power feed is via power supply lines mobile cables, open or enclosed power conductor systems, cable drums. These systems are live up to the terminals of the isolating switch mains connection switch, isolating switch.
During operation or when the main switch is not switched off, electrical components inside enclosures, motors, switchgear cabinets, terminal boxes, etc. This voltage may cause fatal injuries. Pay attention to the sum of the load to be lifted and the load handling attachment. Advise operators to avoid inching as far as possible. It might cause excessive wear and premature failure of the chain hoist.
Inching means giving short pulses to the motor to obtain small movements, e. Certain work and practices are prohibited when using the chain hoist as they may involve danger to life and limb and result in lasting damage to the chain hoist, e. Do not handle suspended loads above persons. Do not pull or drag suspended loads at an angle. Do not pull free fixed or obstructed loads with the chain hoist. Do not exceed the maximum permitted load and permitted load dimensions. Do not leave suspended loads unsupervised.
Do not allow the chain to run over edges. Do not use the chain as a load bearing sling. Always move the chain hoist with push travel trolley by pulling on the load, bottom block or load hook assembly never pull on the control pendant. Do not allow loads to drop when the chain is in a slack condition.
Do not subject the control pendant to inappropriate mechanical loads. Transporting persons, unless lifting devices are specifically approved for transporting persons, is not permitted.
Do not tamper with or manipulate electrical equipment. Chain hoists must be suspended in such a way that they do not collide with stationary equipment and structures, e. Persons under the influence of drugs, alcohol or medicines which affect reactions must not install, operate, put into service, maintain, repair or disassemble chain hoists. Any conversions and modifications to the installation require the written consent of Demag. Work on electrical equipment of chain hoists may only be carried out by qualified electricians in accordance with electrical regulations.
