Neglecting proper maintenance may cause unexpected accidents.
To operate cranes safely, please inspect and maintain crane par
Proper greasing results in less friction between sliding parts and leads to them lasting longer.
Be sure to grease parts appropriately.
Air that enters the oil tank carries in dust and moisture. Over time, hydraulic components generate small amounts of wear debris during operation. For these reasons, it is strongly recommended to regularly replace hydraulic and gear oils.
regularly replace hydraulic and gear oils.
Regularly inspect crane parts jointed with screws and bolts and tighten them as needed. With some parts, failure to do so may lead to the crane falling or other very hazardous accidents.
Check and clean the air cleaner element when the crane has been operated for three months.
Replacing cylinder gaskets and seals
Replace cylinder gaskets and seals every three years after starting to use the product. Replacement periods may vary depending on the frequency of use.
Replacing boom sliding plates and hoist winch brake shoes
Replace boom sliding plates and hoist winch brake shoes every three years after starting to use the product. Replacement periods may vary depending on the frequency of use.
The return filter should be replaced three months after first use, then once every year. Replacement periods may vary depending on the frequency of use.
Clean the suction filter when replacing hydraulic oil. Replace it whenever the filter gets clogged.
Replace the line filter elements once a year after first using the product. When replacing the hydraulic pump, the line filter elements should also be replaced at the same time, then once a year after. Replacement periods may vary depending on the frequency of use.
The hydraulic oil should be replaced three months after first use, then every two years. Replacement periods may vary depending on the frequency of use.
The gear oil for the winch reduction gear should be replaced once a year after first use, then every two years. Replacement periods may vary depending on the frequency of use.
The gear oil for the slewing speed reducer should be replaced once a year after first use, then every two years. Replacement periods may vary depending on the frequency of use.
If the transmitter or rubber parts are deformed or cracked, water may enter inside and damage electrical circuits, resulting in a possible malfunction.
If a switch or the speed lever does not move smoothly, the crane may move when the operator did not intend it to, which may lead to dangerous accidents.
