1 Scope
This part of IEC 60204 applies to the application of electrical and electronic equipment and systems to hoisting machines and related equipment. NOTE 1 In this standard, the term “electrical” includes both electrical and electronic matters (i.e., “electrical equipment” means both the electrical and the electronic equipment). NOTE 2 In the context of this standard, the term “person” refers to any individual and includes those persons who are assigned and instructed by the user or user’s agent(s) in the use and care of the hoisting machine in question. The equipment covered by this standard commences at the point of connection of the supply to the electrical equipment of the hoisting machine (crane-supply-switch) including systems for power supply and control feeders situated outside of the hoisting machine, for example, flexible cables or conductor wires or conductor bars (see Figure 3). NOTE 3 For the requirements for the electrical supply installation in buildings, see IEC 60364. This standard is applicable to equipment or parts of equipment not exceeding 1 000 V a.c. or 1 500 V d.c. between lines and with nominal frequencies not exceeding 200 Hz. NOTE 4 For higher voltages, see IEC 60204-1 1 . Additional and special requirements can apply to the electrical equipment of hoisting machines including those that – are intended for use in open air (i.e., outside buildings or other protective structures); – handle or transport potentially explosive material (for example, paint or sawdust); – are intended for use in potentially explosive and/or flammable atmospheres; – are intended for use in mines. For the purposes of this standard, hoisting machines include cranes of all types, winches of all types, and storage and retrieval machines. The following product groups are included: – overhead travelling cranes; – mobile cranes; – tower cranes; – slewing luffing cranes; – gantry cranes; – offshore cranes; – floating cranes; – winches of all types; – hoists and accessories;
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. 3.1 actuator part of a device to which an external manual action is to be applied NOTE 1 The actuator may take the form of a handle, knob, push-button, roller, plunger, etc. NOTE 2 There are some actuating means that do not require an external actuating force but only an action. NOTE 3 Note the difference between actuator and machine actuator (3.44). 3.2 ambient temperature temperature of the air or other medium where the equipment is to be used 3.3 (electrically) protective barrier part providing protection against direct contact from any usual direction of access [IEV 826-1 2-23] 3.4 cabin-controlled hoisting machine hoisting machine operated from a cabin permanently attached to the hoisting machine 3.5 cable tray cable support consisting of a continuous base with raised edges and no covering NOTE A cable tray may be perforated or mesh. [IEV 826-1 5-08] 3.6 cable trunking system system of closed enclosures comprising a base with a removable cover intended for the complete surrounding of insulated conductors, cables, cords and for the accommodation of other electrical equipment 3.7 concurrent acting in conjunction; used to describe a situation wherein two or more control devices exist in an actuated condition at the same time (but not necessarily synchronously) 3.8 conduit part of a closed wiring system of generally circular cross-section for insulated conductors and/or cables in electrical or communication installations, allowing them to be drawn in and/or replaced NOTE Conduits should be sufficiently closed-jointed so that the insulated conductors and/or cables can only be drawn in and not inserted laterally. [IEV 826-1 5-03] 3.9 control circuit (of a hoisting machine) circuit used for the control, including monitoring, of a hoisting machine and the electrical equipment 3.1 0 control device device connected into the control circuit and used for controlling the operation of the hoisting machine (for example, position sensor, manual control switch, relay, magnetically operated valve, speed sensor) 3.1 1 controlgear switching devices and their combination with associated control, measuring, protective, and regulating equipment, also assemblies of such devices and equipment with associated interconnections, accessories, enclosures, and supporting structures, intended in principle for the control of electrical energy consuming equipment [IEV 441 -1 1 -03, modified] 3.1 2 controlled stop stopping of a hoisting machine motion with electrical power to the machine actuators maintained during the stopping process
