<\/div>EOX with extra-reduced shaft head and reduced pit<\/h2><\/div><\/section>\n\n\n\n

When building in densely populated urban areas, every millimetre and every second counts. With the option of the extra-reduced shaft head and reduced shaft pit, EOX saves on vertical space and<\/span> construction time. Shortening the shaft head to a room-height level means that architects and planners no longer have to design the top floor and roof around a higher elevator shaft, and contractors don’t get caught up with ceiling penetrations and superstructures. <\/span><\/p><\/div><\/div><\/section>\n\n\n\n

In this visualisation, the buildings on the left side of the street feature EOX elevators with a standard shaft head requiring roof superstructures. Buildings on the right feature EOX elevators with extra-reduced shaft head resulting in an obstacle-free roof for terraces, PV panels, etc.<\/mark><\/span><\/p><\/div><\/div><\/section>\n\n\n

Starting from 2.500 mm<\/h3>

Measured from the finished floor of the building top level, the shaft head for your EOX elevator can be reduced from the standard \u22653.280 mm to as low as 2.500 mm. <\/p><\/div><\/div><\/div>

\"\"\/<\/div><\/div>

No complex roof superstructures <\/h3>

The ability to finish the elevator shaft within room height puts an end to “hood”-like roof superstructures, and the top ceiling can be poured as one continuous floor slab.<\/p><\/div><\/div><\/div>

\"\"\/<\/div><\/div>

Architectural design freedom<\/h3>

Architects are free from having to constantly consider an elevator shaft that “sticks out” of the building. In areas with strict building height limits, design-critical space is gained.<\/p><\/div><\/div><\/div>

\"\"\/<\/div><\/div>

Space for PVs, terraces etc.<\/h3>

With the elevator staying below the final floor slab, the building roof becomes an obstacle-free surface that can be used for photovoltaic systems, apartment terraces etc.<\/p><\/div><\/div><\/div>

\"\"\/<\/div><\/div>

Maintenance from the cabin<\/h3>

When the extra-reduced shaft head option is chosen, the EOX cabin comes with a ceiling-integrated foldable working platform, enabling the service technician to perform maintenance safely from the cabin without having to board the cabin roof.<\/p><\/div><\/div><\/div>

\"\"\/<\/div><\/div>

Reduced shaft pit<\/h3>

For the shaft pit, the optional reduction results in a minimum height as low as 450 mm instead of the standard 1.000 mm. Combination of reduced pit option with extra-reduced shaft head is possible, although restrictions may apply.<\/p><\/div><\/div><\/div>

\"\"\/<\/div><\/div>

Available from 450 to 1.000 kg<\/h3>

Both reduction options are available for rated loads from 450 to 1.000 kg. The reduced pit option can be applied to all cabin sizes (incl. flexible dimensions). The extra-reduced shaft head requires standard cabin dimensions.<\/p><\/div><\/div><\/div>

\"\"\/<\/div><\/div>

Certified and quiet<\/h3>

The options for the extra-reduced shaft head and reduced shaft pit are type-tested and conform with EN 81-20\/50 and EN 81-21. Noise performance data proves that EOX is a quiet lift system. The entry value (at 630 kg, 1 m\/s) of just 24 db(A) in adjacent rooms means that an EOX from next door is quieter than a whisper.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/td><\/tr><\/tbody>

Maintenance:<\/strong> In a standard-height shaft head the lift technicians board the cabin roof to service the components located in the shaft head. With the help of an inspection remote control and at very slow speed they can move the cabin. Strict safety protocols incl. mandatory wearing of protective gear are applied.<\/p> <\/div>\n <\/div>\n\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t\t\t

Superstructures<\/strong> limit the use of a building\u2019s roof. Photovoltaic systems have to be planned around it, public or private terraces are difficult to establish. All in all, there\u2019s less space to use or rent with maximum profitability, and the building\u2019s potential market appeal is not fully exploited.<\/p> <\/div>\n <\/div>\n\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t\t\t

Shaft head:<\/strong> Its purpose is to accommodate components located inside the elevator shaft, e.g. the drive. Besides, if the lift technician has to board the cabin roof to perform routine maintenance, a safety zone of at least 1 m is mandatory. For both reasons, a standard elevator shaft head is usually around 3400 mm. The height is measured from the finished floor level of the top landing.<\/p> <\/div>\n <\/div>\n\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t\t\t

Construction: <\/strong>Because a standard shaft head usually exceeds the available room height, it literally has to \u201cstick out\u201d of the roof. The resulting superstructure adds complexity to the construction process \u2013 from the scheduling, to concrete casting, thermal insulation and waterproofing \u2013 and also increases the costs.<\/p> <\/div>\n <\/div>\n\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t\t\t

For the regular maintenance<\/strong> of EOX elevators with an extra-reduced shaft head the lift technician does not need to board the cabin roof. Instead, all service tasks are carried out from within the cabin, thanks to a working platform that folds out from the special cabin ceiling. The mandatory safety zone for the technician to retreat in case of unintended car movement is now inside the cabin rather than on top of it, crucially reducing the required shaft head height. <\/p> <\/div>\n <\/div>\n\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t\t\t

The ceiling-high shaft head reduces construction complexity<\/strong>. Because there is no need for a superstructure on the roof, the final concrete slab can be poured in one go, saving costs and time. The lack of a larger ceiling penetration also improves roofing durability and reduces the risk of water leaks.<\/p> <\/div>\n <\/div>\n\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t\t\t

Buildings where a pitched roof <\/strong>design is desired or required by building regulations benefit on multiple fronts from EOX with an extra-reduced shaft head: Superstructures on the roof are avoided. Additional costs and construction time is saved. Roof space is freed up for photovoltaic or thermal solar systems. In case of a building refurbishment the extra-reduced shaft head makes EOX an ideal candidate for a retrofit installation, because it will literally fit right under the roof.<\/p> <\/div>\n <\/div>\n\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t\t\t

Whether it\u2019s the creation of penthouse apartments, private or community terraces, maisonettes or rooftop gardens \u2013 there\u2019s a certainty for architects, planners and constructors that the lift won\u2019t get in the way of their creative ideas or execution plans.<\/p> <\/div>\n <\/div>\n\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t\t\t

Further information on the application of extra-reduced shaft head and reduced pit<\/strong><\/p>\n

The extra-reduced shaft head and reduced pit options are available exclusively for EOX elevators with max. 1 m\/s and \u22641000 kg. Reduced shaft pit is applicable to all cabin sizes, including flexible cabin sizes. Extra-reduced shaft head is applicable only to standard dimension cabins: 450 kg (1000\u00d71250 and 1000\u00d71300 mm), 630 kg (1100\u00d71400 mm), 825 kg (1350\u00d71400 mm) and 1000 kg (1100\u00d72100 mm). Minimum achievable shaft head is dependent on the chosen rated load, cabin height, door height and door type as well as door model. For example, the lowest extra-reduced shaft head of 2500 mm is achieved at 630 kg with 2100 mm cabin height and a low-buildup door model of 2000 mm height. Combination of extra-reduced shaft head and reduced pit is possible, although restrictions may apply depending on the specific configuration of your EOX elevator. Your TK Elevator contact will gladly guide you through the planning process for your project.<\/p>\n <\/div>\n\t\t\t\t\t <\/div>\n
