However, like any lifting equipment, Flex Lifting cranes also require regular maintenance to ensure safety, efficiency and long service life.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Following the manufacturer\u2019s instructions, periodically checking the hydraulic system, verifying structural integrity and monitoring battery condition are essential activities to ensure the safety, reliability and durability of the machine.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A crane that is not properly maintained may be subject to premature wear, malfunctions or hazardous situations during lifting operations. For this reason, we have collected some good maintenance practices specifically for the Flex Lifting range of electric counterbalanced cranes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Before moving on to the practical tips, let us first understand what an electric counterbalanced crane is.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><b>What are Flex Lifting electric counterbalanced cranes?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Flex Lifting <\/span><a href=\"https:\/\/www.flexlifting.com\/en\/product\/flex-g500sbl-electric-swivel-crane-with-single-electric-boom-500-kg-capacity\/\"><span style=\"font-weight: 400;\">electric counterbalanced cranes<\/span><\/a><span style=\"font-weight: 400;\"> are battery-powered mobile indoor cranes, designed to lift, handle and position loads safely and precisely.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Unlike other lifting solutions that require stabilizers or anchoring points, Flex Lifting cranes use an integrated counterweight system that ensures stability during operations. This allows the operator to work practically even in confined spaces, without having to position stabilizers on the floor.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Thanks to their compact structure, wheeled movement and the different configurations available, Flex Lifting cranes are particularly suitable for:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Mechanical workshops;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Production departments;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Industrial warehouses;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Assembly lines;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Machinery maintenance;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Handling of moulds, mechanical components, engines, equipment and industrial loads.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The Flex Lifting range includes models with different capacities, configurations and control systems, from manual versions to semi-electric and electric cranes with radio remote control, telescopic boom and proportional movements.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><b>Rated capacity depends on outreach<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">One of the most important aspects to consider when using a counterbalanced crane is that the lifting capacity is not always the same in every boom position.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The maximum capacity indicated for a crane normally refers to a specific configuration, often with the boom in its shortest position. As the boom is extended, the outreach increases and the available lifting capacity decreases.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For this reason, before each lifting operation, it is essential to:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Know the real weight of the load to be lifted;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Check the boom position or extension being used;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Always consult the crane\u2019s load chart;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Ensure that the capacity indicated for that specific configuration is higher than the weight of the load.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Underestimating this aspect can compromise the stability of the crane and create risks for the operator, the load and the surrounding environment.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><b>Checks before use<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Before using a Flex Lifting crane, it is recommended to carry out a general visual inspection of the machine. This simple habit helps identify any anomalies before they can become more serious problems.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The main elements to check are:<\/span><\/p>\n<p><b>Crane structure<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\">Check that the frame, boom and telescopic sections do not show any deformation, cracks, visible damage or loose bolts.<\/span><\/p>\n<p><b>Hook and safety devices<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\">Make sure that the hook is intact, not deformed, and that the safety latch works correctly.<\/span><\/p>\n<p><b>Hydraulic system<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\">Check that there are no oil leaks, damaged hoses or loose fittings.
