Modular system for cargo lifts

A young company on the lift market: elevatec has been offering its modular cargo lifts since the beginning of this year. The product is available in three versions.

Patrick Müller is venturing a new start with elevatec. After selling his company in the field of cargo lifts in 2021, he decided to once again establish a company in 2023. "The challenge was developing a product capable of modular deployment and produced as a building block system. The advantages are low storage requirements, lean production and short delivery times," explained the managing partner of the company, based in Würselen near Aachen.

The core of the development is a building block system covering every aspect, such as drive, lifting columns, carriage, transport cage, landing doors and machinery protective fence. Only minimal changes to the building infrastructure were needed when installing the cargo lifts. "Our concept manages without the classic walled lift shaft. We house the travel path if need be in a machinery protective fence," according to the state board mechanical technician.

Moreover, use of a high-floor cage in combination with a ramp made it possible to dispense completely with a pit. "In short, the alterations consist merely of a few attachment points." The first lifts had already been installed this year.

The transport cage can be up to 16 m². The lifting height is twelve metres, allowing travel up to five stops. The nominal speed is up to 15 m/min. The accessible cargo lifts are electronically driven with chain drive and motor brake. The frequency-controlled motor is suitable for S1 permanent operation. A high-performance spur gear transmission drives a shaft which carries the sprockets for driving the eightfold over-dimensioned duplex chains.

The lifting column is a welded structure made of precision steel profiles. It uses precision rollers to guide the carriage, which apart from the transport cage also carries the safety gear, chain tension sensor and measuring system for exact position determination. The cargo lift is available in three versions, from 500 kg to 4,000 kg payload.

Version 1: Mono
"Mono" consists of one lifting column. Depending on the cage version, this cargo lift can carry a payload of up to 500 kg. The dimensions of the standard transport cage are 1,700 x 1,100 x 1,170 mm. The height of the transport cage platform is 15 mm.

Version 2: Twin
"Twin" is composed of two lifting columns. Depending on the cage version, this cargo lift can carry a payload of up to 1,500 kg. The transport cage is made to measure. In the Twin, it varies between 1,700 x 1,100 x 1,240 mm and a maximum of 4,000 x 2,500 x 1,240 mm. In accordance with EN 81-31, the transport cage has an interior height of 1,150 mm.

Version 3: Quad
"Quad" is delivered with four lifting columns. Depending on the cage version, this cargo lift can carry a payload of up to 4,000 kg. The transport cage is made to measure. In the Quad, it varies between 1,700 x 1,700 x 1,240 mm and a maximum of 4,000 x 4,000 x 1,240 mm. In accordance with EN 81-31, the transport cage has an interior height of 1,150 mm.

High vertical integration

All components are developed and produced at the company location, according to elevate. This high vertical integration ensured quality and reliability. "The safety components come from the area of passenger transport and meet the very highest requirements," Patrick Müller promised.

The lifts were technically equipped to ensure that in the event of any malfunction and any electronically detectable, unforeseen event, an emergency stop immediately occurred to protect people, material and the lift.

The safety gear specially developed for the modular lift system was type tested and certified by TÜV Süd Industrie Service. The certificate was presented to the company at interlift 2023.
