Когда упоминается аббревиатура SDLG, сразу становится понятно, что речь идет о фронтальном погрузчике. Производитель строительной техники SDLG входит в сотню лучших производителей Китая, что побуждает постоянно работать над повышением качества и применением новых разработок и технологий для создания спецтехники. Более 30% российского рынка китайских погрузчиков занимает именно этот бренд, который является партнером Volvo, что проявляет всю надежность погрузочной техники SDLG в работе.

Обзор погрузчика SDLG

Погрузчик SDLG: характеристики и инструкция

Фронтальные колесные погрузчики SDLG предназначены для выполнения работ, связанных с загрузкой сыпучими грузами. При этом успешно справляется с землеройными, расчищающими и выравнивающими функциями. Такая техника способна частично заменить экскаватор.

Фронтальный погрузчик SDLG предназначен для всесезонной эксплуатации и ориентирован на европейского потребителя. В зимнее время кроме погрузочных работ, служит в качестве снегоуборочной техники. Летом активно используется для выполнения тяжелых работ со строительным мусором разной фракции, песком, щебнем и разными типами грунта.

Фронтальные погрузчики SDLG относятся к группе сочлененных одноковшевых погрузчиков на колесной базе. Несколько поколений фронтальных погрузчиков постоянно обновляются, пополняя модельный ряд.  Производитель позаботился о широких эксплуатационных возможностях свое техники и выпускает погрузчики самой разной комплектации и грузоподъемности.

В самой просто комплектации погрузчики SDLG имеют рычаги для управления и оснащаются обычной печкой для обогрева и вентилирования. Полная комплектация предполагает наличие кондиционера, управление джойстиками и даже установку штатной магнитолы. Для работы в условиях российских регионов предусмотрена установка немецкого предпускового подогревателя двигателя Eberspeaher. Заботясь о многофункциональных качествах фронтальных погрузчиков, производитель предусмотрел навесное оборудование для выполнения различных работ, которое легко меняется с помощью устройства быстрой замены.

Погрузчик SDLG: характеристики и инструкция

Дополнительное оборудование для погрузчиков SDLG:

  • ковши для тяжелых, легких и скальных грунтов;
  • боковой ковш;
  • объемный ковш для легких грузов;
  • челюстной ковш 4 в 1;
  • вилы для паллет;
  • турбо — , лесо — , сенозахват;
  • тяжелый и легкий поворотные и прямые отвалы.

Для погрузчиков SDLG, как и для большей части китайской техники, характерны невысоким качеством в мелочах. Наиболее очевидно это при осмотре кабины – неплотно прилегающие уплотнители, некачественная покраска, слабая проводка. В остальном погрузчики SDLG характеризуются хорошей работоспособностью, без аварийных остановок во время эксплуатации. Кроме этого, цены  на погрузчики SDLG в несколько раз ниже европейских или американских аналогов, что делает технику данного бренда доступной для небольших хозяйств.

Характеристики погрузчиков SDLG

Модельный ряд погрузчиков SDLG представлен техникой, предназначенной для выполнения многоуровневых задач разной сложности. Это проявляется в наличии малогабаритной техники с малой грузоподъемностью, и моделями среднего и тяжелого класса. Грузоподъемность фронтальных погрузчиков, в зависимости от модели, колеблется от 1,8 до 8 тонн.

Погрузчики  SDLG оснащаются двигателями разной мощности, начиная от 58 л.с. и заканчивая 300 л.с. Наиболее часто встречаются двигатели собственного производства или других китайских производителей. Для европейского рынка предлагаются двигатели Volvo и их партнеров.

Коробки передач есть как механические, так и автоматические, с различным количеством скоростных режимов. Трансмиссия с обязательной задней передачей позволяет легко управлять техникой и выполнять сложные схемы маневрирования.

Погрузчики SDLG обладают рядом преимущественных характеристик:

  • высокая вместимость подъемного ковша;
  • высокая скорость подъема ковша с грузом;
  • оснащение функцией автоматического выравнивания;
  • простое управление гидравликой;
  • невысокая стоимость официального ТО компенсирует мелкие заводские дефекты.

Погрузчик SDLG – инструкция к эксплуатации

Руководство по эксплуатации погрузчиков SDLG включает в себя основные технические данные о моделях и их особенностях. Для некоторых моделей прилагается инструкция не только по эксплуатации, но и по ремонту. В руководстве можно ознакомиться с возможными неисправностями рабочего оборудования, коробки передач, электрики, тормозной и рулевой систем, а также способы первичного устранения этих неполадок.

Погрузчик SDLG: характеристики и инструкция

В руководстве четко описаны принципы работы основных устройств и приемы работы с ними. Также указаны правила проведения технического обслуживания, прилагается карта планового ТО с рекомендациями по маркам заменяемых горюче-смазочных жидкостей.

Замена масла в погрузчике SDLG

Турбокомпрессоры дизельных моторов, устанавливаемых на погрузчики SDLG, отличаются особой чувствительностью к чистоте масла. Замена масла происходит во время каждого сервисного ТО, т.е. через каждые 250 моточасов. Через каждые 500 рабочих часов необходима замена трансмиссионного и гидравлического масла. Погрузчики SDLG неприхотливы к маслам того или иного производителя, главное условие, чтобы они соответствовали своему назначению и происходила своевременная замена.

Моторное масло рекомендовано использовать согласно условий эксплуатации и типа двигателя. Производитель рекомендует использовать синтетические и полусинтетические масла. Например, неплохой вариант для дизельных двигателей — GProfi 10w-40.

Масло для гидравлической системы погрузчиков SDLG подойдет марки МГЕ или обычное российское гидравлическое веретенное.

Масло в коробку SDLG заливается трансмиссионное №6 и №8 согласно китайским техническим классификациям масел. Возможно использование летнего масла API CF-4/SG SAE15W/40. Категорически запрещено лить в АКПП погрузчика моторное или масло иного назначения.
