Wether the design shown is still in production , it still shows the "Original" design which has been updated/ uprated for heavier caravans, especially for the ones shown in Saxo' photographs.
Alko caravan chassis with pre-punched holes for the fitting of jacking brackets were introduced in 1991. A glance at Alko’s current website shows that the 800 kg jacking bracket, first introduced in the 1990s is still in production looking exactly the same as when it was first designed.
But then 25 to 30 years ago, caravans were much lighter. Within my own Avondale’s range dated from the 2000’s, an 8mtr shipping length, 6-berth, twin axle Argente caravan had an MTPLM of only 1600Kgs so it could be fitted with an Alko jacking bracket.
It’s only in more recent years that Alko has added to the range because the MTPLM’s of caravans have increased, so now in addition to the 800Kgs bracket, there is a 1000Kgs bracket.
It is an addition to the range. Not an updated/modified/upgraded version of a failed previous design. Providing an Alko bracket is fitted within its specification and used according to recommendations, it is, and always has been, a reliable means of lifting a caravan.
