This Indian Standard prescribes the requirements for manually operated gearless pulling and lifting machines, which are general purpose material handling apparatus. Rather than relying on gears to lift the load, like gear lifting machines, these gearless program units use a set of clamps and levers that grab hold of and pull the wire rope allowing for lifting or pulling in horizontal directions. They’re valued for their versatility and for functioning in areas where conventional lift equipment is unable to operate. The specification addresses vital aspects including design, construction, materials, and performance. It determines the load capacity, operational safety, efficiency and wear resistance. Tests range from load-bearing ability and repeated use endurance to rope grip strength and the tendency for slippage. Manufacturers can give the assurance that when their machines comply with IS 5604:1984, they will perform in safety under different operating conditions in the field, without impairing the safety of the user.

The BIS certification under IS 5604:1984 provides a number of benefits to manufacturers, users, and the industry. For manufacturers, certification validates conformity with national standards, enhances brand credibility, and provides access to government and private projects where certified equipment is a requirement. It also creates export opportunities, in that products with this certification are known to international markets. For professional users, certified machines assure safe operation and load management as well as high productivity, low long-term costs, and a sense of peace at work. Because they are employed for tough applications like construction, railways, power transmission, shipyards and mining- safety and performance are the main concerns. Certification The best way to prevent accidents, minimize equipment downtime and establish long-term reliability. As well as being a long-term investment, certified machines often have lower maintenance costs due to the fact that they are high spec and need to meet particular robustness criteria.
