M. A. Zavery Company

Safety with Grade 80:

• To achieve the consistent high level of quality and reliability of our products.
• Electronically controlled chain machine have been specially built and developed  to provide advanced manufacturing process.
• High grade alloy steel are carefully chosen.
• Strick controll of material acceptence and processing is carried out by skilled personnel.
• Sofisticated multi process heat treatment techniques have been developed.
• Non destructive testings systems are used with magnatic crackdetection (magna flux systems) beign applied during final inspection.
• Close dimentional controls are carried out at all stages of manufacturer.
• To ensure the change have a high capacity to absorb shock loading, they are produced so that they will give a minimum extensions of 20% under a destruction test before fracture occures.
• They are also subject to sample bend testings.

We offer a wide range of steel wire rope that are manufactured by using high grade alloy steel chain and German technologies. These steel wire rope are light weighted and compact.

Features:

• The breaking load figures is above kilo newton.             
  
• To obtain values in metric tonne, multiply the figures by 0.102.
• Maximum safe working load = Breaking load of rope / factor of safety (Min -5)

Wire rope slings are manufactured from qualitative raw
material for breaking load figures as shown in kilo Newton.
These slings are also used to get the values in metric tones. Their maximum
safe working load is equals to the ratio of breaking load of rope and the
safety factors.
