Being a specialist in
long reach solutions which cater predominately for dredging and deep excavation
work. It is inevitable for us to complement our long reach solution with
various design of clamshell bucket, providing our customer with unparallel
value added 1 stop services. Clamshell buckets
are commonly used for dredging application, loading and unloading industrial
wastes, grains, sands and so forth in addition to digging and excavation.
We design, develops and manufacture both hydraulic and mechanical clamshell use
on excavator and crane.
Hydraulic
Clamshell
The CS series hydraulic clamshell
bucket is designed to be attached onto an
excavator. The dual hydraulic cylinders/rams mounted on the outer rim of the
bucket provides excellent digging force. The inner side of the bucket has a
smooth surface for easy unloading of high viscosity material such as mud and
clay, while the outer layer is reinforce with additional layer of wear strips.
The bowl's radius has been optimize to match with the locus of the hydraulic
cylinder/ram to deliver consistence full load for maximum productivity.
Hydraulic designs are meant for attaching to an excavator while the mechanical
cable operated are designed to work with a broad range of canes. Ours grab are
constructed with high tensile steel and wear resistant steel with capacity
starting from 1 cubic meter and upward. |

Mechanical/Cable
Clamshell
The fully mechanical clamshell is designed specifically to be used on a crane
for large capacity dredging and digging application. The opening and closing
action is operated via cable. The inner side of the bucket has a smooth surface
for easy unloading of high viscosity material such as mud and clay, while the
outer layer is reinforce with additional layer of wear strips. The hanger is
constructed with high tensile steel.
The design concept
and criteria of a dredging versus a general purpose loading/unloading
mechanical/cable clamshell differs greatly due to its differences in the nature
of application and working condition. The geometry and weight distribution of a
good clamshell design plays a significant role in determining its overall
efficiency.

Hydraulic
Clamshell for Telescopic Arm
Telescopic
dipper arms are gaining popularity where dip excavation work needs to be
carried out in tightly spaced environment. The single centered
mount hydraulic cylinder/ram clamshell bucket is specifically design to be used
on a telescopic dipper arm. The unique and powerful customized hydraulic
cylinder/ram delivers smooth opening and closing action with strong
penetration force which is a pre-requisite for an effective telescopic
clamshell bucket. |
