Types of wire rope pulley blocks

Types of Wire Rope Pulley Blocks:

• Fixed Pulley Blocks: Change the direction of the force but do not provide mechanical advantage.
• Movable Pulley Blocks: Both change the direction and multiply the force applied, providing mechanical advantage.
• Combination Blocks: A combination of fixed and movable pulleys to achieve greater mechanical advantage.
• Single Fall vs. Multi-Fall: Single fall means the rope makes one pass through the block, while multi-fall means multiple passes, increasing mechanical advantage but reducing speed.
