A drop table system can intelligently provide truck assembly movement with a controller connected to at least one lifting column and a single inclinometer with the inclinometer positioned at a geometric center of a drop table platform. The drop table platform can be suspended with the at least one lifting column prior to a detection of drop table platform tilt with the inclinometer. The tilt may be corrected by altering operation of the at least one lifting column to orient the drop table platform in a level configuration.

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.

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.

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.

A turntable in modular pie or other sections, which sections can be added or taken away in concentric rings from a base version of the turntable in order to scale the size and capacity of that turntable to accommodate a wide range of size and loading needs.

Disclosed is a pit cover and method of installing the same. The pit cover includes a plate having a hole defining an area. A block having a threaded hole may be affixed to a bottom surface of the plate such that the threaded hole aligns with the area. A support is associated with the foundation and a groove is defined by one of the pit cover or the support. A protrusion is defined by the other one of the pit cover or the support. The groove narrows from a first width towards a second width. The first width is disposed relative to the second width such that insertion of the protrusion into the groove causes an end of the protrusion to pass the first width prior to passing the second width. The protrusion interacts with the groove to align the pit cover at a predetermined position relative to the foundation.
