Chain block <\/strong><\/h2>\n

Manual chain hoists are commonly known as chain blocks and are designed for heavy duty lifting and materials handling operations. Chain blocks raise and lower loads by pulling on the hand chain. Chain blocks can be of single or double fall configurations depending on the capacity of the block.<\/p>\n

Construction and warehouse workers use manual chain blocks to lift heavy loads manually.\u00a0 These pulleys, also called manual chain hoists, are capable of lifting varying weights, depending on the type and model chosen for the job.\u00a0 Manual chain blocks are designed with a thick steel hook at the top of a thick steel square.\u00a0 Wrapped around the square several times is a steel rope, which serves as the pulley chain for lifting the load.\u00a0 A second steel hook is attached to the end of the chain.<\/p>\n

There are three main types of hand chain hoist available which are:<\/p>\n

    \n
  1. Hook suspended <\/strong>which is a hoist with hooks top and bottom.<\/li>\n
  2. The hoist unit fitted with a\u00a0push travel trolley<\/strong>(manual trolley), which enables manual movement up and down a beam.<\/li>\n
  3. A hoist with a\u00a0geared trolley\u00a0<\/strong>integrated in to the hoisting unit, which via the pulling of a chain drive the trolley can glide up and down a beam with the utmost ease.<\/li>\n<\/ol>\n

    We also offer a range of completely\u00a0stainless steel hand chain blocks<\/strong>\u00a0which are not presently advertised online though we will be adding them to our web site shortly.<\/p>\n

    When choosing a manual chain block model, workers must consider the size of the load they\u2019ll be lifting.\u00a0 Since chain blocks are sold in different sizes, it may be advantageous to choose a size or two larger than what is needed for the immediate job.\u00a0 This will allow construction workers to accommodate larger loads if it becomes necessary in the future.<\/p>\n

    Inspection before use <\/strong><\/h2>\n

    Ensure that the chain block name plate and WLL is clearly visible and legible.<\/p>\n

    The pre-use inspection for a chain block should include the following:<\/p>\n
