Our Products
Our Complete range of products are Manila Rope Pulley Block with Bearing and Chain Slings.
Many hoists are package hoists, built as one unit in a single housing, generally designed for ten-year life, but the life calculation is based on an industry standard when calculating actual lifeCommon small portable hoists are of two main types, the chain hoist or chain blockand the wire rope or cable type.
Chain hoists may have a lever to actuate the hoist or have a loop of operating chain that one pulls through the block (known traditionally as a chain fall) which then activates the block to take up the main lifting chain.

Chain slings can be manufactured using permanent, welded coupling links, or if preferred, mechanical coupling links for quicker "in the field" assemblies. Either way, the sling must have an attached identification tag providing the grade, size, reach, type of sling, working load limit at a specific angle of lift, and serial number.
Relative to other types of slings, chain slings have the poorest strength/weight ratio, best abrasion and cut resistance, average elongation and shock resistance, best flexibility, and best resistance to high temperatures.
