摘要： A lifting column can provide optimized performance with a nut gap system that efficiently and precisely measures a nut gap during lifting operations. The nut gap system can have a rotating core onto which a nut and traveler are positioned. The nut can be separated from the traveler by a nut gap that is monitored by at least one sensor that continuously extends through the nut to access the nut gap.

摘要： A drop table can employ a number of lifting columns respectively arranged with a nut and traveler each positioned on a rotating core with the nut separated from the traveler by a nut gap. The nut gap may be measured with a first sensor positioned within the nut and the first sensor detecting a nut gap distance with a first sensing feature. The first sensor can be changed to a second sensor that detects the nut gap distance with a second sensing feature that is different than the first sensing feature.

摘要： A drop table can employ one or more shearing drive couplings to optimize lifting operations. The drop table can have a motor physically attached to a first lifting column via a first rotating input shaft and to a second lifting column via a second rotating input shaft. Each rotating input shaft is connected to the motor by a drive coupling having a shearing insert positioned between a drive shaft and a collar.

摘要： A drop table can provide optimized lifting operations by employing motor feedback to generate and adapt a lifting strategy that controls lifting parameters. A lifting module may be connected to a first motor and consist of a lifting controller. The first motor can be mechanically coupled to a first lifting column by a first transmission and to a second lifting column by a second transmission. A service component can be lowered with the first and second lifting columns by activating the first motor that provides motor feedback. A lifting strategy can be generated in response to the motor feedback and subsequently executed to move the service component to a servicing position.
