Innovative Vertical Transportation Solution for Very Large Goods Elevator.

When transporting very large heavy goods or even complete lorries, hydraulic lifts or rigid chain technology have typically been used. Elevating Studio hereby publishes a new innovative way to transport very large loads at higher speeds, by using standard elevator geared or gearless elevator machine technology. The proposed solution uses normal and standard componentry, and the solution can be engineered and used by any of the elevator manufacturers based on their own technology. This guarantees the availability of future spare part needs from the suppliers’ own stock. Most importantly, the proposed technology has significant advantages in terms of traffic performance, reliability, energy efficiency and environmental sustainability.

The solution we hereby propose uses multiple elevator machines, either geared or gearless and typically based on asynchronous technology (or others).

All elevator machines will operate simultaneously as one combined traction solution, where one end of each set of ropes is fixed to multiple independently guided counterweight frames. The other end is fixed to the guided elevator car, which is consisting of multiple interconnected car frames. The car side is thus one solid construction. This solution will ensure that the multiple motors automatically synchronize the torque needed of all machines, while the car speed can be controlled by one or more synchronized drives.

The system can be built in segments. For example, 5000 kg segments. Obviously, these segments can be sized to any required load. Each segment consists of one traction machine with a traction sheave with appropriate rope grooves or belt guidance, one independently guided counterweight frame at one end and one car frame at the other end, with ropes/belts guided over the traction sheave. The number of segments is increased for larger car size and/or higher loads. If we apply a 5,000 kg segment, six (6) segments can be interconnected to carry a payload of 30,000 kgs. Each counterweight and/or car frame can be provided with safety gear.

The suspension ratio used can be any suspension ratio typically used in the lift industry. One would normally expect suspension ratios between 1:1 (direct acting) and up to 6:1 blocking ratios. It goes without saying that even higher ratios can be applied.

Elevating Studio believes this technology is very beneficial for the transport of large to very large loads. By publicizing this solution, we want to prevent any patenting of the proposed solution.
