REDUCED to sale.

You’re bidding on  total of 3 Ludwig Hunger Brake servicing machines machines. Two F308 /G-CE and one S 331-CE. The units work as great as they look. This stuff is made from Germany. Would be perfect for a shop owner who appreciates high end tech.

1. S 331-CE Brake Shoe Grinder

The S 331 belt grinding machine is ideal for cleaning and derusting brake shoes. 

Uneven corrosion and oxidation deposits as well as adhesive residues are removed from old brake shoes by grinding. Cleaning of the brake shoe surface after removal of the old linings is essential for a secure platform and vibration free seating of the new lining. 

The dust extractor (accessory) with pre-separator provides a clean work- ing environment. Grinding sparks are extinguished in a pre-separator before they reach the dust extractor. 

The abrasive belt can be replaced easily. 

Brake shoes up to a width of 270 mm (10“-shoes) can be machined. 

HIGHLIGHTS

• The working radius can be adjusted by the adjustable buffer.

USEFUL FOR

• Removal of old brake lining remains, adhesive residues and rust

Description

The S 331 brake shoe grinder with grinding roll is a low priced but high effective machine for cleaning and derusting brake shoes. Uneven corrosion and oxidation deposits as well as adhesive residues are removed from old brake shoes by grinding. Cleaning of the brake shoe surface after removal of the old linings is essential for a secure platform and vibration free seating of the new lining.

• The inclination of machine table towards grinding roll guides the brake shoe without effort.
• The working radius can be adjusted by the adjustable buffer.
• The flat grinding table ensures a proper seat of the brake shoe during operation and thus a perfectly flat ground shoe.
• The change of the grinding belt is easy and quick.
• Capacity: Brake shoes up to 10″ (270 mm).

2. F308 /G-CE Version Brake lining turning machine

HIGHLIGHTS

• Rotation in either direction; all brake linings are turned in the direction of the wheel rotation.
• The design allows to use a toolholder with very little overhang.
• Simple adaption by the height-adjustable lifting and mounting trolley
• Tool slide with a numeric read out

USEFUL FOR

• Turning of brake linings of commercial vehicles directly on the wheel hub
• Turning of brake linings on stub axles
• Turning of brake linings with mounted inner taper roller bearing

Description:

The profiling of brake linings in position, i.e. on the axle, guarantees safe braking values from the outset. Furthermore, the linings make contact over their full working surface. Overloading and consequent over-heating caused by partial contact is eliminated and both brake lining and brake drum life extended.

• The F 308 can rotate in either direction. This enables all brake linings to be turned on the vehicle in the same direction as the wheel rotation, so that the braking forces on both wheels of the vehicle are particularly closely matched.
• The F 308 is supplied complete with a lifting and mounting trolley which makes the machine extremely easy to handle. For skimming brake linings on hub reduction axles and on conventional stub axles the machine can be attached without any problem.
• The skimming process is carried out fully automatically up to the automatic termination of the intermittent feed, when the preset turning depth has been reached. Machining times are very short due to the speed of rotation of 100 rpm and a steplessly variable feed. On the basis of experience, the feed is set to 0.6 mm/rev. in our works.
• The tool slide is equipped with a numeric read out which enables a faster, easier and faultless adjustment of the tools.
• The design of the F 308 allows a toolholder with very little overhang to be used. This results in optimum concentricity, parallelism and surface finish.
• Equipped with integrated suction device to protect your health.
• “Special versions” of the F 308 upon request
