Dispersed screws offer more security and for lifting equipment many manufacturers of lifting equipment for cars used inferior screws reliability in the past which were produced in the rolling process. Because today’s cars are harder the stick-slip dreaded thread bars produced in the rolling procedure occurs when these lifting systems now also increasingly effect. Therefore, more and more manufacturers of lifting equipment for cars switch to dispersed threaded spindles. The screws used for the jacks have to withstand extreme loads, but be precisely on the other hand, to avoid a block. Here the spinal procedure has established itself as a superior technology, as evidenced by the success of Bornemann thread Technology GmbH in Delligsen. Whether changing the tire or any repair work a lifting system of under the vehicle is a must in every car workshop.

Threads allow a smooth starting and braking during the stroke with lifting heights up to over 2000 mm. In addition, they offer an irrefutable Security advantage over hydraulic lifting equipment: brake failure of the actuator the threads of its own. Depending on the weight lifting equipment are doing with one, two or four columns used. For many years Bornemann thread technology supplying numerous European manufacturers of truck – and Bahnhebeanlagen with screws and nuts under heavy loads. Lifting equipment for cars were produced in the past due to reduced loads usually with inferior quality, manufactured in the rolling process, threaded spindles.

But growing numbers of car tares due to more and more units and safety equipment has resulted in that more rolled thread drop the so-called stick-slip effect to the victims. All lifting equipment will be permanently destroyed by seized nuts. The stick-slip effect arises because nuts insert for high loads and the contact surface to the threaded spindle is always smooth. This is the lubricant from the gap beyond pressed Finally, it comes to the blockade,”Moritz says Soden, sales manager at Bornemann thread technology.
