Excavator Attachments Hydraulic Quick Coupler
What is the purpose of a quick coupler?
Quick couplers (also called quick hitches) are used with
construction machines to allow the rapid change of working tools or
buckets and attachments on the machine.
A good quick hitch coupler should be durable and able to withstand
the weight and pressure of your machine. When choosing a quick
hitch coupler, you should also consider how often you will use it.
If you use this accessory frequently, choose a heavy-duty unit, but
a lighter-duty model may suffice for occasional users
What are the different types of quick couplers for mini excavators?
There are two primary types of quick couplers: mechanical and
hydraulic. Each of these has its advantages and specific
applications in the field.
What is the difference between a manual coupler and a hydraulic
coupler?
Manual couplers are all about hands-on changeovers, meaning you'll
need to get down and dirty to switch attachments. They're
straightforward and budget-friendly but can slow you down. On the
flip side, hydraulic couplers let you swap tools without leaving
your seat, making them a real timesaver.
What is a mechanical quick coupler?
Quick couplers are mechanical devices designed to connect different
types of attachments, such as buckets, grapples, or forks, to heavy
equipment, such as excavators or loaders. Their primary function is
to enable rapid attachment changeouts, replacing the need for
manual attachment mounting and dismounting
Why do we use couplers?
The usage of couplers in construction reduces significant amount of
conventional lap length and saves time and materials. The standard
recommended tests such as tensile test, slip test, cyclic test and
fatigue test ensures the quality of coupler in transmitting the
forces with proper rebar yielding failure
