Сопровождаемый штабелер Hyster от 1 до 2 т.

Многие годы на рынке погрузчиков ажиотажным спросом пользовались модели вилочных автопогрузчиков с дизельным двигателем. Погрузчики с электродвигателем ценились только для складов с повышенными нормами выбросов СО 2. За последнее десятилетие эта ситуация в корне изменилась, наметилась совсем другая тенденция. Прежде всего, это связывают с рывком в развитии техники, а именно в двигателестроении. Многие электродвигатели встали на одну ступень по мощности с бензиновыми и дизельными двигателями, при этом сохранили свои главные показатели экологичности и отсутствия затрат на топливо. К такой технике относится современный Komatsu FB15-12 с электродвигателем, высота подъема вил которого — 3 м. Компания Komatsu идеально решила эту проблему за счет установки нескольких силовых агрегатов, которые имеют больший показатель КПД и имеют небольшие габариты. На модели FB15-12 установлена пара таких силовых агрегатов, каждый мощностью 4,5 кВт, таким образом, вилочный погрузчик с электродвигателем встал в один ряд по мощности с автопогрузчиками. За счет тяги электродвигателя данная модель погрузчика способна перемещать грузы под наклоном более 15°. Технические решения и особенности управления Электропогрузчик Komatsu FB15-12 обладает лучшим тяговым моментом, чем его предшественники. Это достигается установкой отдельных моторчиков на каждое ведущее колесо вилочного электропогрузчика. Данная модель славится своей маневренностью, достигаемой за счет автоматической регулировки колесного дифференциала. Благодаря системе отдельных моторчиков повышается проходимость электропогрузчика, к примеру, на обледенелых участках дороги. Система электронной педали газа позволяет наиболее точно задать погрузчику ускорение. Система создана и рассчитана для улучшения показателей маневренности и безопасности движения. Управление Komatsu FB15-12 упрощает функции водителя-оператора. Водитель не производит лишних телодвижений, движение машины производится за счет переключателя, расположенного на рукояти одного из рычагов. Это стало возможным благодаря установке дисплея на рабочей панели оператора. На дисплей выводится вся информация, касаемая погрузчика и выполняемых на нем процессах. Одной из новых возможностей стала возможность самостоятельного выставления необходимых параметров работы погрузчика. Данная возможность, прежде всего, влияет на производительность машины. Количество часов автономной работы увеличивается за счет отдельного мотора, установленного для всего оборудования погрузчика: электроника и механизм поднятия груза. Перемещение мачты осуществляется плавно без рывков, за счет равномерной подачи масла в систему. Регулировка скорости Komatsu FB15-12 При каждом нажатии кнопки функции ограничения скорости хода со стрелкой вниз — 16 осуществляется попеременное включение ON и выключение OFF опции ограничения скорости хода. Когда функция ограничения скорости хода включена, появляется индикатор символ черепахи — 8. Одновременно в течение 2 секунд мигает значение заданной предельной скорости хода. Это устанавливает режим ограничения скорости хода, и начинает мигать соответствующий индикатор. Индикатор предельной скорости хода перестает мигать, значение предельной скорости установлено. Замена аккумуляторных батарей Максимальная производительность Komatsu FB15-12 достигается и за счет быстрой и простой замены аккумулятора. Извлечение аккумуляторов происходит в бок. Замена аккумуляторов может производиться и за счет другого электропогрузчика. Такой момент позволяет существенно сократить время простоя техники. Также аккумуляторы можно зарядить и не снимая их с электропогрузчика, аккумуляторы имеют своё собственное зарядное устройство, подключаемое к сети в 380 В. Комфорт кабины оператора Кабина электропогрузчика Komatsu FB15-12 Komatsu, держа шаг в современных технологиях, не забыла и о комфорте. Кресло оператора оборудовано несколькими регулировками. Автоматическая система поддержки спины снижает нагрузку на позвоночник оператора. В кресло встроена система подогрева, что обеспечивает комфортную работу оператора в холодных условиях. Кресло оператора оснащено ремнем безопасности и удобными подлокотниками, не лишающими оператора подвижности. Конструкция кабины обладает повышенным показателем обзора, что в свою очередь напрямую влияет на производительность. Аккумуляторы расположены максимально снизу, что обеспечивает заниженный центр тяжести и увеличивает пространство для кабины. Количество мертвых зон при обзоре сокращено за счет выгодного расположения кресла оператора, чуть левее от центра кабины. Komatsu FB15-12 славится отсутствием механизмов связи колес и рулевого управления. Это позволяет уменьшить вероятность передачи толчков и вибраций на руль оператора. Поворот колес осуществляется за счет гидростатической системы, а электроника техники способна автоматически возвращать колеса в стандартное прямое направление. Кабина оператора снабжена системой «контроля присутствия оператора в кабине». Если оператор покидает кабину по какой-либо причине, то электроника автоматически блокирует все операции выполняемые в данный момент. Система срабатывает за счет датчика веса, расположенного под креслом оператора.

We know you need your forklift to work and we promise to help get you what you need as quickly and inexpensively as we can to get your Hyster forklift back up and running. Поводковые штабелеры отличает низкое энергопотребление, а также возможность горизонтального перемещения грузовой тары на средние расстояния. Высокий мощностной потенциал и хорошие тяговые характеристики способствуют обработке большого количества грузов в расчете за один час работы. Один нерадивый сотрудник, проверяя плавкие предохранители, умудрился один потерять, а другой спалить. У нас зарадное устройство на 80вольт 70А. Также надо проверять систему гидравлики на герметичность, проверять затяжку болтов и винтов. К тому же, данное устройство является одним из элементов защиты от опрокидывания. Такие модели предназначены для интенсивного использования, в том числе в стесненной и труднодоступной местности — там, где не способны проехать более габаритные и неповоротливые штабелеры.
