The 1994 Grabber

[Superkoala]

Hello Eurobrick

I present you today a double rebuilt I have completed few days ago. This is not a real project, I needed to make a break from power functions and I had some spare time due to low workload.

Back in 1994, Lego released the Universal Set “8062 with Storage Case”: One briefing case with instruction for 7 different models. I was 7 years old when it was released and unfortunately I never have owned it.

One of the 7 build from set 8062 was a claw-mounted vehicle. In the main lines, this is a 6-wheeler, 4 wheels steering via HOG, with an arm raised through a worm gear and the claw, controlled from the side of the vehicle.
I recommend you to visit the great and well documented Technicopedia website from Blackbird if you want to have additional info on all the models from 8062 set.

Studless version:

The first MOC is simply a studless rebuild version of the original model from 1994. The design is exactly the same: 6 wheelers (same wheels of course) with a massive claw and a massive operator cabin. The only additions are the seat in the cabin and the working light above the cabin.

The functions are also exactly the same :
- 4 wheels steering through an HOG placed above the cabin
- Erection of the arm though a worm gear installed behind the cabin
- Operation of the claw trough a worm gear and universal joint controlled from the side of the vehicle

 

 

Modernized version

This second version is made more with a 2018 standard. The design has not really evolved except the cabin which is smaller and moved forward. 

It is still a 6 wheelers with 4 wheels steering, but the HOG control is in the middle of the vehicle and the central axle has been connected to a 2-cylinder engine placed at the rear.

The main arm is raised using a mini-LA and the control to open/close are now directly on the claw. It was not possible to install them somewhere else due to the mini LA and the motor.

 

Here’s a digital view of the mechanical parts :

Bonus:

Both MOC’s digital models can be downloaded by clicking on the picture just here below (Please note that I haven’t updated model after physical build, so they may contain building mistake).

Convert old studfull sets to studless and then modernize it is an interesting process. I will probably try to make others in the future, between two major MOC.

Thank you for reading!

 Actually that would be great re-release of this set in studies style for Technic beginners

Sorry, but those studded originals look better.

I sort of agree with @Jurss . Maybe this wasn't a great set to reproduce studless. The studless replica is beautiful but your interpretation isn't my favorite. Still, interesting topic!

The case is great for testing offroad capability on models

Love this set, rebuild them all like 20 times from back in the day.

Thank you all for your feedback.

I never been a great fan of the studfull Technic sets on an aesthetic aspect only. But I however consider these old sets were the glory time of Lego Technic. Original models that have never been remade since, more than one or two alternative models per box... Good ol'time.

Whilst I fully understand the concept of rebuilding the older sets in studless techniques, and appreciate the effort and skill in doing so, I still prefer the studfull versions.  

You have inspired me to break out the 8062 parts though, and spend a few hours reliving the joys of the set.  Thank you for that
