Applications
The design and capacity of the 650 XXL 25/50 make it suitable for specific, demanding site environments:
- High-rise construction: Transporting personnel and materials, including curtain walling and cladding panels, to significant heights.
- Commercial & public utility projects: Moving large prefabricated components, palletised materials, and equipment during the construction of large-footprint buildings.
- Infrastructure & renovation: Facilitating the movement of heavy structural elements and machinery on bridges, industrial sites, and large-scale refurbishment projects.
Key properties
- Internal length up to 5.0 m: Accommodates long materials such as scaffolding, rebar, or extensive facade panels without requiring disassembly.
- Internal width of 2.5 m: Provides ample space for bulky items, including palletised glazing units and large modular components, which can be loaded directly with a forklift.
- Payload of 2,600 kg: Suitable for heavy single loads, reducing the number of required journeys and potentially decreasing associated labour costs by up to 20%.
- Capacity for 31 persons: Functions as an effective passenger hoist, enabling rapid movement of large crews up and down the structure.
- Travel speed up to 54 m/min: The high speed minimises transit time on tall structures, contributing to productivity gains of up to 10% on high-demand projects.
- Maximum lifting height of 150 m: Reaches the upper levels of most high-rise buildings. This height is extendable upon request following a site-specific assessment by our design and engineering team.
Site operation & handling
The hoist is installed and operated according to precise technical parameters to ensure safety and performance.
- Assembly: Built on a galvanised steel rail mast, anchored to the structure at specified intervals.
- Drive system: Powered by a 3x11 kW motor assembly with a Variable Frequency Controller (VFC), which enables smooth starting and stopping and uses up to 40% less power than previous models.
- Power supply: Fed via a cable trolley system using a 25 mm² traction cable and a 35 mm² fixed cable.
- Twin configuration: Can be installed in a twin-car configuration on a single mast. This setup doubles lifting capacity and optimises the flow of materials and personnel, significantly reducing wait times. It is an ideal solution for integration with a common tower.
Frequently asked questions
What is the maximum height this hoist can reach?
What is the maximum height this hoist can reach?
The standard configuration allows for a lifting height of 150 metres. For projects exceeding this height, the mast can be extended following a structural review and project-specific engineering.
How many people can travel in the hoist at once?
How many people can travel in the hoist at once?
The Alimak Scando 650 XXL 25/50 is rated for a maximum of 31 persons.
Can this lift be used in a twin configuration?
Can this lift be used in a twin configuration?
Yes, it can be installed in a twin-car setup on a single mast. The second car can have a width of 2.5 m, 2.0 m, or 1.5 m, providing flexibility for project logistics.
What are the power supply requirements?
What are the power supply requirements?
The hoist requires a 400V, 125A, 50 Hz power supply.
How is the hoist secured against overspeed?
How is the hoist secured against overspeed?
It is equipped with an Alimak GFDrII safety device, a centrifugal brake system that activates mechanically if the hoist exceeds its rated tripping speed of 1.2 m/s.
How does the VFC drive improve performance?
How does the VFC drive improve performance?
The variable frequency controller ensures smooth acceleration and deceleration, reducing mechanical wear. It also lowers the starting current and optimises power consumption, leading to significant energy savings and lower operating costs. The efficiency of this system can be further analysed and improved, increasing the efficiency of the hoist operator by up to 30%.
