BUCKET WHEEL EXCAVATOR KWK-910 - SKW

The lowering of the discharge boom is implemented with a
hydraulic cylinder. This is a simple and easy solution which
ensures a wide range of lowering and which is suitable for
the implementation in a relatively light suspended pipe
structure for the discharge boom.
The digging system with 2 x 500 kW drives is an effect of
planning to reach the unitary cutting force of 200 kN/m. A
modern planetary gear of 1000 kW drives the bucket wheel
through an easily disassembled tooth coupling and a shield
fixed to the wheel with spring screws. A single layer wheel
with a self-cleaning chute is equipped with characteristic
spokes ensuring the transfer of the large side digging loads.
The digging system is suspended with joints to the
extension structure through a moment lever with a joint.
The overload device of an extremely short operational time
and high precision of the overload settings is a proof of the
highest technical level in the field of excavator security
against the effects of impact loads.
16 buckets are placed at the perimeter of the bucket wheel
of 10m diameter, which favourably decreases the dynamics
of the digging process and ensures the size reduction of the
output. The intentionally shaped geometry of the bucket
corners made of special alloy is a result of many years of
experience and tests carried in the conditions of hard
diggable deposits.
