Safety System U30
Class 1 Machine Fastener

The MATO Safety System U30 is extremely effective when installed in high strength belts where safety and reliability is essential.

The main applications are:

Belt Fasteners and Connecting Pins

U30 series
The Safety Ststem offers plate material of stainless steel and staple material of spring steel. 
The plate and staple design and configuration have been obtimised though rigorous testing.
The splice provides a very strong connection and exceptional service life.

The MATO connecting pins are specially developed stainless steel cable and armour wrap.
Standard: e.g. P1S    Long Life: e.g. P1C.

 

The fasteners are produced in 200mm long strips, packed for the standard belt widths of 1000 and 1200mm.
The fasteners are also available with a stainless steel staple for corrosive applications. Stainless version: e.g. U35S.

U30+ series
The fastener can be supplied as a sealed version, which minimises sifting of the fine materials during conveying. It's possible to grease the loop area in order to increase the lifetime of the connecting pin.

For safe and easy installation it is recommended to use the screw connecting pins for the sealed fasteners.
Standard: e.g. P1SG    Long life: e.g. P1CG.

Belt Lacing Machines

THe MATO belt lacing machines are available with manual or a pnematic lacer and the clamping frames are available in sizes to suit the required belt width.
Both types of lacing machines are designed to install the full range of fastener sizes in the U30 System.
Reliable and low maintenance is guaranteed due to the assembly of quality engineered parts.

Manual lacer: Advancing and fastener installation is performed manually.
Pneumatic lacer: Advancing is performed manually and fastener installation is performed pneumatically.

MATO recommends system accessories which optimise the installation of Safety System U30 and increases the service life of the splice.

System accessories such as Belt Clamps and Belt Skiver are described in seperate leaflets.

Belt Skiver

If the belt cover is 2mm or thicker it is recommended to skive leaving 1 - 1,5mm of cover above the carcass. The belt skiver is used in the clamping frame of the belt lacing machine. Various skiver blades are available.

Skiver blade for belt thickness 5 - 20mm

Skiver blade HD for belt thickness 15 - 30mm

Wave and bow stop


Illustration: Wavemaster kit.

Different versions available for belts up to 1600kN/m.

Optimat

For belts up to 2000kN/m. The Optimat system provides easy gauging of the belt thickness and setting the skiver.

Advantages:

Use the patented MATO systems to prevent waves and bows in the belt. The tensioned wire rope will eliminate edge stress, improve connecting of the two spliced ends and minimise scraper wear.
