Indeed, on their production line, their operators have to <strong>wedge heavy parts<\/strong>, even very heavy ones such as the inner boom of the telescopic arm. This one must be held and pushed into place to set the wedges.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_column_text css_animation=&#8221;left-to-right&#8221;]<span style=\"font-weight: 400;\">Until today, operators were using <strong>manual effort levers<\/strong>. Those levers have very small and metallic effort surfaces. In addition, by using this tool by hand, the agents are close to the machine and to the strong thrusts parts. When tilting and pushing, <strong>the tool can slip at any time<\/strong>. The operators could find themselves clamped with the hand clenched between the parts, which would return to their original position.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The cases of work accidents are then high, resulting in handicaps for the staff concerned. On the industry side, this will lead to administrative procedures, time losses on the machine&#8217;s manufacturing, and finally money losses.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This is why the manufacturer was looking for a <strong>more reliable, more secure, and simpler solution to protect his staff<\/strong>. To meet his needs, some constraints had to be respected :<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\"><b>weight to be pushed<\/b>: about 100kg,<\/span><\/li>\n<li><span style=\"font-weight: 400;\"><b>available width:<\/b> 100 mm,<\/span><\/li>\n<li><span style=\"font-weight: 400;\">a<b>vailable length<\/b>: 3 to 4 m,<\/span><\/li>\n<li><span style=\"font-weight: 400;\"><b>insertion zone<\/b>: between 5 and 10 mm,<\/span><\/li>\n<li><b>lifting height:<\/b><span style=\"font-weight: 400;\"> 4mm.<\/span><\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;14264&#8243; img_size=&#8221;large&#8221;][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css_animation=&#8221;left-to-right&#8221;]<\/p>\n<h2><span style=\"color: #00a7e1;\"><b>Pronal Lifting bag as an inflatable effort lever<\/b><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To meet the needs of our partner, we diverted one of our leading products: the <a href=\"https:\/\/www.pronal.com\/en\/product\/lifting-bags\/vtr-lifting-bags-for-transformer-winding\/\">VTR lifting bag<\/a>. This inflatable solution is used in particular by electrical transformers, for the wedging and adjustment of their winding.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Its conception and qualities allow it to meet every expectation of the users. As for its basic use, it has many advantages :<\/span><\/p>\n<ul>\n<li><strong> protection of the\u00a0 pressurized parts thanks to its flexible surface,<\/strong><\/li>\n<li><strong> simple and fast use compared to traditional methods,<\/strong><\/li>\n<li><strong> reduction of the operators working time,<\/strong><\/li>\n<li><strong> easy insertion in the most confined spaces thanks to its low thickness,<\/strong><\/li>\n<li><strong> tailored to each situation.<\/strong><\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;14139&#8243; img_size=&#8221;large&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;14144&#8243; img_size=&#8221;large&#8221;][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css_animation=&#8221;left-to-right&#8221;]<span style=\"font-weight: 400;\">As its contact surface with the parts is larger than the metallic lever, <strong>the thrust is better distributed<\/strong>. In addition, being made of rubber, <strong>its adherence means that it does not slip<\/strong> against smooth surfaces of the parts. The risks of work accidents are then drastically reduced.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The use of the inflatable system is simple. It is done with the help of an air inlet which will put the solution under pressure. This application allows the operator to have more distance on the heavy mechanical part and <strong>to be more protected<\/strong>. Thanks to the lifting bag, <strong>he gains in safety but also in comfort<\/strong> because once inflated, the operator can use both of his hands. <\/span><span style=\"font-weight: 400;\">The system is also fast to use, speeding up the wedging part and thus, the production lines of the handling equipment.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, Pronal supplied <strong>12 lifting bags of 9 mm wide<\/strong>, with a <strong>100mm outlet<\/strong> in the edge for air supply.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=&#8221;stretch_row_content_no_spaces&#8221;][vc_column][vc_pr_testimonials_single citation=&#8221;PRONAL lifting bags are totally innovative in our company. They are used to hold the different elements of the booms of our machines during the wedging operations. The operator is then in possession of both of his hands, which brings him work comfort and safety during the operation.
