Lödige acquires Northern Elevator
Lödige Industries, a supplier of lift solutions, acquires the British lift installation, repairs and maintenance provider Northern Elevator Limited.
Three new draft standards have just appeared, they will all be harmonised under the Machinery Directive. Lodging objections to all drafts is still possible. We have summarised the changes for you:
Electrically and hydraulically operated service lifts
The draft EN 81-30:2022 was published by CEN in July 2022. It was implemented nationally as draft DIN EN 81-30:2022 with the August 2022 issue. Objections are possible up to 15 September 2022. The standard is to be harmonised under the EU Machinery Directive 2006/42/EU.
The standards specifies the safety rules for the construction and installation of permanently installed new service lifts with
– a traction,
– Contents draft DIN EN 81-31:2022 positive or
– Contents draft DIN EN 81-31:2022 hydraulic drive
It applies to service lifts which
– serve predefined levels,
– a carrier the interior of which is regarded as inaccessible to persons on account of its dimensions and means of construction,
– suspended by ropes or chains or
– jack and
– moving between rigid guide rails inclined by not more than 15° to the vertical.
This document covers service lifts not exceeding 300 kg and not intended to transport persons.
The following changes were made compared to DIN EN 81-3:2011-06:
a) All important health and safety requirements from the Directive 2006/42/EC were included.
– reference to EMC,
– review of the design,
– requirements of the manuals for the erection, testing and failure;
b) Requirements were updated taking into account EN 81-20:2020 and EN 81-50:2020.
– flammability of car material;
– shutdown of machines;
– rope guides
– thickness of doors and lift shaft
– type plates,
c) Improvements in safety due to changes in proven technology being taken into account.
– performance level;
– door locks;
– electrical equipment;
d) Changes in the state of the art were taken into account
– ropes and connections;
– existing buildings;
– emergency power operation;
– properties of fluids;
e) Errors reported in hydraulic equations were corrected;
f) The text was clarified: accessible/inaccessible shaft;
g) References to other standards were updated according to the progress in this area, consequently, all standards now include a date.
h) The informative annex “List of significant hazards” was added;
i) The informative annex “Building interface” was added;
j) The annex ZA replaces the previous annex ZA and annex ZB. The new informative annex ZA (about the connection with EU Directive 2006/42/EC) is now an integral part of this document
Accessible goods only lifts
The draft EN 81-31:2022 was published by CEN in June 2022. It was implemented nationally as draft DIN EN 81-31:2022 with the August 2022 issue. Objections are possible up to 8 September 2022. The standard is to be harmonised under the EU Machinery Directive 2006/42/EU.
The standard specifies safety rules for accessible goods only lifts with traction or positive drive and new hydraulic accessible goods only lifts.
– The goods only lifts are permanently installed in restricted areas,
– they are only used by instructed persons (users),
– serve fixed and permanent landing levels, having a load carrying unit,
– made of a single load-carrying area, designed for the transportation of goods only,
– moving along a fixed path not inclined by more than 15° to the vertical.
– The nominal speed of 1 m/s may not be exceeded.
– The standard covers accessible goods only lifts with a rated load exceeding 300 kg, which are not intended for the transport of people, since the operating elements cannot be operated from inside the carrier.
The following changes were made compared to DIN EN 81-31:2010-08:
– Requirements were updated taking into account EN 81-20:2020 and EN 81-21:2009+A1:2012.
– The following subjects and contents were reworked:
– thickness of doors, separations, partitions;
– unintentional movement of carriers;
– protection spaces; inspection mode; rope safeguards;
– The application range of the standard was changed:
– no longer overlapping with EN 1570, only if rigid guide rails are used;
– scissor lifts were excluded;
– travel limit was rescinded for type A;
– energy-consuming buffers were not considered;
– The following requirements and verifications were added:
– protective spaces;
– catch devices;
– automatic power-operated doors;
– brake devices.
– Due to changes in proven technology, the contents were adjusted to the state of the art and as a result the safety level was improved; this affects the following subjects and contents:
– work rooms;
– electrical installations;
– relevelling control;
– performance level;
– ropes and connections;
– existing buildings;
– shock factors;
– buffer with non-linear properties;
– alarm system;
– Errors reported in hydraulic equations were corrected;
– The text was more clearly formulated in the following areas:
– pulley room; extreme position of the carrier in the shaft;
– use in restricted / unrestricted access area;
– entrance to shaft / exit from the shaft.
– References to other standards were updated according to the progress in this area, consequently, all standards now include a date.
– The wording was changed:
– from “uncontrolled movement” to “unintended movement”
– from “manual actuation” to “emergency mode”;
– from “safety room” to “protection room”
– from “load carrier” to “carrier”; from “seller” to “manufacturer”
– from “laboratory” to “tester”.
– The informative annex “List of significant hazards” was added;
– The informative annex “Building interface” was added;
– The annex ZA was updated with regard to the mandate M/396 of the European Commission.
Vertical lifting appliance with enclosed carrier intended for use by persons, including persons with disability
The draft EN 81-42:2022 was published by CEN in June 2022. It was implemented nationally as draft DIN EN 81-42:2022 with the August 2022 issue. Objections are possible up to 8 September 2022. The standard is to be harmonised under the EU Machinery Directive 2006/42/EU.
The standard specifies safety rules for the design, manufacturer, installation, maintenance, inspection and disassembly of “Vertical lifting appliances with enclosed carrier intended for use by persons, including persons with disability”.
It applies to:
– permanently installed electrically powered vertical lifting appliances affixed to a building structure,
– intended for use by persons, including persons with disability
– travelling vertically between predefined levels along a guided path whose inclination to the vertical does not exceed 15°,
– lifts supported or sustained by
– rack and pinion,
– rope traction drive,
– noncircular elastomeric-coated suspension means (hereafter called traction belts),
– drum and chain drive,
– rope positive drive,
– chains, toothed belts, screw and nut, guided chain,
– scissors mechanism or hydraulic jack (direct or indirect)
– with enclosed shafts,
– with a rated speed not greater than 0.15 m/s,
– with carrier completely enclosed.
The draft DIN EN 81-42:2022 is a new document and was prepared by the Technical Committee CEN/TC 10 “Lifts, escalators and moving walks”.
