Nowadays, more and more drivers have a good
skill in operating hydraulic excavator. Safety
comes first, only the excavator operator has a good knowledge of safe operating
guidelines can he guarantee the safety of the machine and himself.
Check the ambient to make sure no barriers
or rough terrains will impede the excavator to make a rotation. The crawler
belts should be touched with the ground completely to improve the stability of
the whole machine, which will prevent rollover and collision. The digging
capacity can reach the maximum when the angle between the bucket cylinder and
the rod, the arm cylinder and the bucket rod becomes 90°, the
cutting resistance becomes the minimum when the angle between the bucket teeth
and the ground is 30°. The digging efficiency can be improved when the boom and the
bucket are used simultaneously. As we all know that hydraulic excavator can be used in various constructions, so different operating
techniques should be used in different operating environments.
The excavator bucket should be prevented to
dig rocks as much as possible since the hard rocks will make damage to the
bucket. But when there is no choice, the operator should adjust the machine’s
body and make the bucket cut the rock according to its cracks. Put the bucket
teeth into the cracks of the rock and use the power of the rod. The complete
rocks should be cracked before digging by bucket. Keep the machine stable and
balanced when doing leveling work, it is very important to make a good
coordination between the arm and the bucket for leveling. When the industry excavator is used to lift heavy-duty loads,
the bucket should be put in an accurate position and no person should be close
to the lifting loads, which will cause accident.
