The bulldozer is a crawler tracked tractor, equipped with a substantial
metal plate used to push large quantities of soil, sand and etc.
Bulldozers can be found on a wide range of small scale and large
construction sites, mines and quarries, military bases, heavy industry
factories, and large governmental and public Engineering projects as
well as farming.
Excavators also named excavating machinery are used in excavating
the materials that higher or lower than the levels, and transporting
the materials to the stock yard.
Loader is widely used in road construction,railway construction
construction ，mining construction and etc. The loading machinery
has high efficiency on scraping the bulk materials and is easily
Asynchronous Electric Motor
Asynchronous electric motors, with compact design, low
maintenance and initial cost, are widely applied in driving
machine tool, pump, fan and mining machinery, and they are
especially used in electric fans, refrigerator, air-conditioning and
other Household Electric Appliance.
Industrial DC Motor
Industrial DC motor is an electric motor that runs on direct
current (DC) electricity. By far the most common DC motor
types are the brushed and brush less types, which use internal
and external commutation respectively to create an oscillating
AC current from the DC source.
Large Electric Motor
Large Electric Motor is an automatic device that uses error-
sensing feedback to correct the performance of a mechanism.
The term correctly applies only to systems where the feedback
or error-correction signals help control mechanical position or
Bevel gears are gears where the axes of the two shafts
intersect and the tooth-bearing faces of the gears
themselves are conically shaped. Bevel gears are most often
mounted on shafts that are 90 degrees apart, but can be
designed to work at other angles as well.
Transmission or gearbox are widely applied in Mechanical
Transmission, wind turbines, and also used in agricultural,
industrial, construction, mining and automotive equipments.
Heavy duty Gearboxes are widely used in Packing machinery
for printing industry, Mechanical transmission, Iron and steel
industry, Rolling steel machinery, Construction machinery
and some other high torque situations.
The continuous casting machine is widely used in drawing
slabs during the series process of steel making. Composed
of ladle turret, mold oscillator, foot rolls and bender and
guiding rolls etc., the continuous casting machine protect
the liquid metal oxidized by the harmful gas.
