Description

Block has a single ORBIT of the Ronstan series 55

Kilogram for kilogram of working load, BB and RT Orbit Blocks ™ are the world's lightest. The unique design of the orbital allows the bearing to only be in the active areas of the pulley float. This reduces to a minimum the mass of the return stroke of the inactive and the hub. Weight and size are further reduced in the different configurations of the block. The block with the bearing ball and a single has a system of attack to pulley shaft. The result is the weight as low as possible. The blocks multi-sheave, have only the cheeks intermediate individual and a provision of the head ultra-lightweight and efficient. This gives an advantage of weight savings of 30% compared to the nearest competitor. Other brands connect to only the individual blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy channel steel through the top of the block. The highest working load in its class The available orbital of the ball bearing gives the greatest possible diameter of the raceway of the bearing. This maximizes the performance of the load. The proven bearing system two-stage Ronstan is equipped with ball bearings in acetal for high-compression and a ball bearing secondary complete contact. This gives minimum friction across the full range of work load. The system of pulleys and floating bearings is supported by a load frame with reinforced fiber. The design has been computer-modeled so as to optimize the stress. The Dyneema® Link is produced from the fiber of FSE Robline SK75, which is 10 times more strong and lightweight steel, and provides the final connection from the block to the load point. Attachment safe and easy, The Dyneema® Link is easily mounted and is held in securely by a clip retention printed. The flexible coupling may be left with one end attached to the block during the assembly, no more crickets, and posts lost. The system is compatible with mesh with Dyneema® / Spectra®, the straps and the connection points of carbon, much more of the loops, or the crickets in the steel. Low profile and compact The flexible Dyneema® Link provides a rotation controlled, and an orientation to 0 ° or 90 °. Connects directly to the head of the block rather than a central pillar in the middle. This reduces the weight and provides the lowest profile possible while still allowing a complete joint. Beckets have been carefully designed to minimize the height.
