Cela permet d'\u00e9viter la \u201c prise rapide \u201d qui pourrait obstruer la conduite de votre pompe.<\/p>\n\n\n\n<p>\u2022Ombre et protection : Dans la mesure du possible, garez le camion \u00e0 l'ombre et utilisez des bandes r\u00e9fl\u00e9chissantes pour recouvrir les tuyaux de livraison.<\/p>\n\n\n\n<p>\u2022\u00c9tat du syst\u00e8me hydraulique : une chaleur ambiante \u00e9lev\u00e9e r\u00e9duit la viscosit\u00e9 de l'huile hydraulique. Veillez \u00e0 utiliser une huile \u00e0 haute viscosit\u00e9 adapt\u00e9e aux climats tropicaux. V\u00e9rifiez r\u00e9guli\u00e8rement que le refroidisseur d'huile ne contient pas de poussi\u00e8re ou de d\u00e9bris susceptibles d'entraver la circulation de l'air.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2.

Les moteurs turbocompress\u00e9s, courants sur les mod\u00e8les SANY et Zoomlion modernes, g\u00e8rent mieux cette situation mais subissent tout de m\u00eame des contraintes accrues.<\/p>\n\n\n\n<p>\u2022Efficacit\u00e9 du refroidissement : l'air, plus rar\u00e9fi\u00e9, est moins efficace pour \u00e9vacuer la chaleur. Surveillez attentivement la temp\u00e9rature du moteur, car le point d'\u00e9bullition du liquide de refroidissement est plus bas en haute altitude.<\/p>\n\n\n\n<p>\u2022Conseil d'expert : r\u00e9glez le rapport air\/carburant du moteur pour \u00e9viter un \u201c m\u00e9lange trop riche \u201d, qui entra\u00eene une production excessive de suie et l'encrassement du FAP.
