Q. What are the two types of chain blocks?

A.Hand-operated chain blocks and electric chain blocks are the two major types of chain blocks. Manual chain blocks use human energy to lift a load. The operator pulls on the hand chain to operate the block in either lifting or lowering tasks. The applied force is multiplied inside the block by a gear mechanism. Thus, this feature of manual blocks comes in very handy in lifting heavy objects. Manual chain blocks are simple devices to use, portable, and do not consume power. These blocks are used in places where electricity is not available or mobility holds priority. They are manufactured with various weight capacities, ranging from light loads to several tons.Electric chain blocks lift and lower loads using electric motors. The motors drive the gears and the lifting chain, thereby increasing the speed of operations and decreasing the physical exertion needed. Electric chain blocks can be considered when lifting tasks are heavy or repetitive. Often they are found in factories and workshops where there is access to power. Some electric chain blocks come with remote controls for safety and convenience.Both types use hooks to hold the load firmly. The safety of both types should be assured first before using them, and neither of the two types must be used in excess of their rated weight limits. Choose manual or electric based on need. Think about the load size. Consider the location. Also, how often you lift. Manual is good for light or rare lifts. Electric suits for heavy or frequent lifts. Pick what fits your work. Both these lifters will perform the job for which they were designed in different situations.
