• Warning and Safety Information for Ropeblock Lifting and Rigging Components

Material
Most blocks look quite similar from the outside, however the choice of material and the method of fabrication and assembly can result in a totally different product or factor of safety. The clear design and engineering philosophy enables Ropeblock to select materials and production methods without limitations. Some of the more commonly used materials and methods are:

• Sheaves in ductile cast iron, cast steel, nylon, welded fabricated or from solid steel
• Low temperature steels with high impact resistance
• Double sealed roller bearings
• Bronze or composite bushings
• Lubrication channels in traverse and centre pin

Testing
All blocks and overhaul balls are subject to an intensive compliancy test protocol. The most important test that is executed is the proof load and serialization protocol. The item will be subject to a pre-defined proof load, that is determined and in accordance with the respective standard, rule or regulation. Some of more common proof load requirements are:

• According to ILO convention 152
• ASME B30.1
• DNV Rules for lifting appliances
• ABS Lifting
• API 2C
• Lloyd’s Register
   

Finish
An important requirement in the total scope of production is the finishing, or corrosion protection. Ropeblock has developed comprehensive finishing methods in accordance with ISO standards. This allows for a certain level of flexibility depending on the segment specific requirements. Ropeblock’s finish recommendation for each segment can be found in the table below. Although yellow with optional black striping is considered to be standard for many applications, customer specific systems and colours are very well possible.
