Norms & Standards

We at IMEM Lifts specialise in designing lifts to comply with all the applicable local, national and international standards required, including those governing wheelchair lifts.


EN81-20/50 standards. What else?

From 1 September 2017, all new lifts that are installed must to be designed to suit the requirements of the new harmonised standards EN81-20 and EN81-50.

EN81-20 and EN81-50. Ready to face the future.

On 1 September 2017, the harmonised European standards EN 81-1 and EN 81-2, which since 1985 have set out the minimum specifications for the design and manufacture of electric and hydraulic lifts, will be definitively superseded by the new harmonised standards EN 81-20 and EN 81-50, after a three-year transition period since their initial publication in August 2014. The updating of the standards covers not only substantial changes in lift systems' technical specifications, but a change in their whole format: EN 81-1 covered the construction of lifts and the testing of lift components in the design and manufacture of electric lifts and EN 81-2 did the same for hydraulic lifts. The new standards are arranged in an entirely different way: EN 81-20 covers the technical requirements for the construction of both electric and hydraulic lifts and EN 81-50 covers the design rules and testing of lift components for both types of lift. The technical requirements established by the new standards represent a significant improvement in safety for lift users and service personnel, as well as for all users of the buildings which house them. Some of the more notable changes include: LIFT SHAFT Newly defined strength and dimension requirements for doors and hatchway access into the shaft, for inspection and rescue access and for entry into the machine room, the strength of shaft walls, the pit floor and the partitions within shafts, the impact-resistance of any glass used, the durability of landing-door toe-boards and the specifications of counterweight screens and of the pit exit options when the car is immobilised. The installation of air-conditioning and sprinkler systems is covered, and new lighting specifications are introduced. PIT Specifications for pit access ladders, for stopping devices, for an inspection control station in the pit and for an alarm button in accordance with EN 81-28. REFUGE SPACES ON THE CAR ROOF & IN THE PIT New definition of minimum dimensions, placement and warning signs. CAR DOORS & LANDING DOORS Increases in strength requirements and changes in the emergency unlocking system and the position of the unlocking triangle. MACHINE & PULLEY ROOMS New lighting specifications. LIFT CAR Newly defined minimum strength of car walls, fire resistance of in-car materials, resistance of glass or mirrors used, specifications of car apron, of car roof, of car roof balustrade and toe-board, the upgrading of service and emergency lighting and the specification of information required to be listed on labels and notices. GUIDE RAILS New design criteria, new calculation methods and new machining standards. SAFETY GEAR New definition of roping requirements and the replacement of minimum rope diameter requirements. BUFFERS Fixings to the car and/or counterweight, and the disappearance of energy-accumulation type buffers with buffered return movement. ELECTRICAL COMPONENTS Updating of inspection control stations and definition of bridge connectors for maintenance. Please remember that from 1 September 2017 all lifts installed and put into service in the European Union must fully comply with the specifications set out in these two new standards. IMEM Lifts is delighted to announce that from 1 January 2016 our entire range of lifts will be available to our customers in full compliance with the new harmonised standards EN 81-20 and EN 81-50, should you wish to take early advantage of these improvements. “The integration of the new standards into our lift designs is firmly in line with our unshakeable commitment to offering our customers the most innovative and up-to-date products on the market, compliant with the full range of present and even future standards and at the cutting edge of technological development”. Félix De las Heras. IMEM Lifts’ Quality Director.

Lifts for reduced dimensions. EN81-21 regulation

We offer a wide range of solutions for adapting our lifts to shaft spaces with reduced shallow headroom, pit or unusual dimensions following the EN81-21 regulation. One of our best selling products is the MRL gearless lift for reduced dimensions: The Silens-Pro Compact®. The Silens-Pro Compact® is the ideal solution for existing buildings with limited space available for lift installation. This product is available in a wide range of load capacities and is perfectly suited to handling traffic conditions in the vast majority of existing buildings. It can also be installed in spaces with very limited available pit depth (350mm minimum, in full compliance with the EN 81-21 standard) and headroom clearance space (a minimum of 2650mm in accordance with EN 81-21). All the advantages of a state-of-the-art MRL gearless lift comfortably fitted into a highly compact product. We can also provide solutions designed to suit the particular project in hand: hydraulic, electric with a machine room sited above, below or on the side of the shaft, drum driven systems, whatever is the most appropriate.

EN81-72 Firefighter lifts

Many buildings and environments require our lifts to be provided with additional protection controls and signals. We ensure the protection and equipment against water and follow the regulation to ease the rescue from inside or outside the lift car in case of fire: emergency trapdoors, accessible ladders, priority recall for the firefighter lift and use of the lift under firefighters control.

EN81-71 lift standard. Vandal Resistant Lifts

The growing demand of resistant lifts in unguarded public areas against acts of vandalism has leaded us to follow the EN81-71 lift regulation, which defines the testing methodology and the classification of lifts in terms of vandal resistance

BREEAM: energy-saving lifts

BREEAM (the Building Research Establishment Environmental Assessment Method) is the world leader and standard-setter in the evaluation and certification of sustainable building design, and is the technically most advanced method of assessment available.

DDA compliant lifts

The DDA requires reasonable provision to be made for people with disabilities to gain access to and use buildings and their facilities. As experienced designers, manufacturers and suppliers of complete DDA lift systems with hundreds of projects undertaken in the UK
