Abstract
This disclosure describes a belt driven block and tackle system. Traditionally flat belts have many advantages over wire ropes, including maintenance-free operation for an extended service life, a low cost of manufacture, and a reduced physical size in at least one dimension for a given set of working loads. The system includes a block and tackle including first pair of outer sheaves and a first pair of inner sheaves positioned between the first pair of outer sheaves, and a belt extending from a central point, around the first inner pair of sheaves, the first outer pair of sheaves, and out of the block and tackle.
Claims5
A system for a belt driven block and tackle comprising:
- a first block and tackle comprising:
- a first pair of outer sheaves;
- a first pair of inner sheaves positioned between the first pair of outer sheaves;
- a support plate comprising a first face and a second face, wherein a sheave of the first pair of outer sheaves and a sheave of the first pair of inner sheaves are mounted to the first face;
- and
- a belt extending from a central point, around the first inner pair of sheaves, around the first outer pair of sheaves, and out of the first block and tackle;
- a second block and tackle comprising:
- a second pair of outer sheaves;
- and
- a second pair of inner sheaves between the second pair of outer sheaves, wherein the belt further extends from the central point, around the second inner pair of sheaves and around the second outer pair of sheaves out of the second block and tackle and wherein a sheave of the second pair of outer sheaves and a sheave of the second pair of inner sheaves are mounted to the second face;
- and
- a set of off-plane sheaves positioned to redirect the belt from the first block and tackle to the second block and tackle.
