The hook
arm of the ISUZU hook loader is the main working device, which is used
for hoisting, unloading or tipping the waste.There
are four main types of pull arm structures: straight type, telescopic type,
folding type and composite type, of which the composite type is a combination
of telescopic pull arm type and folding type, which is rare in practical
applications, so today we will talk about the characteristics of the other
three structures:
The straight
type is an L-shaped structure, and the L-shaped angle is a right angle. The
advantages of this structure are simple structure, low difficulty in production
and assembly, and simple operation.The disadvantage is that a large operating
space is required during the operation, the loading angle is large, the
accuracy is relatively low, the turning range is small, and the shank is low,
which requires a low chassis, so this type of hook is suitable for vehicles with
a wheelbase of less than 4.2 meters.
The
telescopic type is also called a sleeve hook arm. Although it looks like a
straight type, the lifting arm can be extended and retracted when working.The
advantages of this structure are strong and durable, large bearing capacity,
freely retractable length, stable operation process, small impact, and low
requirements on the shape of the inner arc of the hook head.The
disadvantage is that the structure is more complicated, the production and
installation process have high technological requirements, and the arm
increases the weight of the whole vehicle, which naturally reduces the load
capacity.Therefore, this structure is usually used in models
with a wheelbase of 4.5 meters and above.
The
foldable type is also used less, the shank is low, and the hook arm hook is
hydraulically driven to fold freely at 0-90 degrees.This
type is usually customized according to customer requirements.
