Ochsner Rear Loader film (part 1)

(Michel Ferro Collection) Ochsner rear loader- Functionally similar to the Dennis Paxit which was based on this system named for its inventor, Jacob Ochsner (Switzerland). The inverted drawer pusher blade shoves the charge upward, and the packer blade sweeps the face of it. Filmed by KUKA to contrast with the speed of their 210 rotary.

This is like the trucks used by Hart District Council (Fleet, Hampshire) in 1977 and 1979~80. The earlier machine (possibly made by Warwick?) did not have an upper packing plate but just the basic Ochsner inverted drawer. The latter machine (possibly a Dennis Paxit) had the packing mechanism as seen in this film. Fuel consumption must have been large as both trucks packed continuously. Large items such as old steel electric heater and house removal boxes were 'digested' slowly but effectively.

The one you mentioned without the packing plate was probably an SD Pakamatic.

Jacob Ochsner, along with Fernand Rey, may rightly be credited with inventing the hydraulic rear load packer truck as we know it. These films were made by KUKA to show how slow the packer performed. However, Ochsner's (then) 30-year old design actually holds up quite well. Maybe not as hungry as the KUKA Shark, but not bad either.

l haven't seen a SD Pakamatic or Dennis

Paxit since the early 80's.The screw-type

ones appear to have done a dodo too,we

had Commers with Glover,Webb,and Liversidge bodies down in Cornwall when

l was a kid in the 70's,with the odd Pakamatic or Paxit.Does KUKA still make

the Rotopress?Saw one years ago called

a shark-think it was the same machine.

Rotopresses were quite widespread on

Wealden Council in Sussex,but they've all

vanished in favour of Variopress types.

It is the same machine, See Michel's article on KUKA history at ClassicRefuseTrucks main page

Certainly the old SD ones l saw as a kid

used to splutter abit with bulky stuff-the screw type seemed better.But l don't think

the Ochsner's designers had bulky refuse

in mind did they?

I agree: the Ochsner packer dates to the early 1930's, and was probably not intended for bulk duty. The film here was made by KUKA, most likely to show how antiquated this design was, especially when contrasted with the modern KUKA rotaries. Still, the old Ochsner design does not do that badly all things considered.

[AG3304]

Very interesting read.Thanks for that,and the old film of Rotopresses being built,tested and entering service.

True, but keep in mind this is a design dating from the *early* 1930s. This (along with the French Rey-loader) was the world's first mass-production refuse packer. By the time this film was made, probably early 60s, it was becoming obsolete, though it would live on through the 1970's (at least in the form of the Dennis Paxit).

This garbage truck SUCKS!!!

The SD Revopak is 100 times better at bulk garbage than this.

[ClassicRefuseTrucks]

Clearly the film demonstrates how the Ochsner system was not well suited to bulk collections, and this film was made to compare it with the speed of KUKA's rotary system. In fairness, Ochsner's system was revolutionary when it was designed in the early 1930's, and was still in fairly wide use even into the early 1970s!
