Types of electric height adjustable desk frame explained


a) Single column. one motor, one telescopic leg. Series: 501-7 and 501-19
Primarily there are 2 types of multi-leg desk frame

b) single motor with driveshaft(s) taking drive to the other leg(s). Series: 501-11, 501-17, 501-27, 501-29, 501-49, 501-43
c) motors in each leg that are syncronised. Series 501-23.


The most significant performance difference is that single motor desk frames do not need to be loaded evenly to acheive their lift capacity, eg.. a 501-11 could have an 80kg electronic micro-scope on one end and nothing on the other and it will lift as if the load were evenly spread.


There is also a reasonable argument that a single motor system by virtue of having less parts and by being mechanical is inherently more reliable. The traverse steel beam that houses the driveshaft also acts as a very strong brace to give solid construction for the whole frame.


With the Conset driveshaft system it is unheard of for the leg height to become electronically out of sync. The traverse on a Conset desk is always a fixed length for strong rigidity, even for the telescopic width frames the traverse beam is bolted at a fixed width once assembled.


'out of sync' can occur with any electronic synchronised leg system including the Conset 501-23. In this system each leg has a motor and then electronics are used to synchronise these to lift at exactly the same speed. A motor fault or failure or an error in the electronics can cause the synchronisation to fail.


a,b and c are all exceptionally reliable so here we give extreme examples for multi-leg usage, this may help explain further:..


1) If a symmetrical, open, heavy duty design is the priority ie.. for a boardroom meeting table then 501-23 should be the first choice.
2) If the frame is for a workbench used day in day out with heavy equipment sometimes placed to one side then 501-11 should be the first choice.


3) For 100 office desks with a wide range of users all with typical Pc, printer, books etc.. loaded anywhere on their desk top then the inherent mechanical reliability of a Conset single motor system is hard to argue against. 100 desks then = 100 motors an no synchronisation electronics. Any from type b above meet this criteria.
