A hydraulic quick hitch coupler sits between the excavator stick and the attachment. You pin the coupler to the machine once. Attachments then connect to the coupler instead of the stick. A hydraulic cylinder runs the locking mechanism, and the operator controls it from the cab.
You may also see this product called a quick hitch, quick coupler, hydraulic quick coupler or excavator quick attach.
Our hydraulic quick hitch coupler is a core component for excavators and loaders. It replaces front-end attachments such as breaker hammers, buckets and grabs quickly.
1. Mount the coupler. Pin it to the stick and the bucket linkage. It normally stays on the machine.
2. Pick up the attachment. The operator hooks the coupler onto the attachment front pin.
3. Seat the rear pin. The operator curls the coupler until the rear pin reaches the locking position.
4. Lock hydraulically. A switch in the cab sends oil to the coupler cylinder, and the lock closes.
5. Release. Reversing the cylinder opens the lock, and the operator sets the attachment down.
The coupler cylinder connects to the excavator auxiliary hydraulic line. The BHQC series lists a hydraulic flow of 10-20 l/min, so confirm that your machine can supply it.
• Faster changeovers. Switching from a bucket to a breaker takes less time, so the excavator works more of the shift.
• Safer operation. The operator stays in the cab instead of driving out pins by hand.
• More versatility. One excavator can dig, break, grab and load in the same day.
• Less manual handling. Fewer pin changes mean fewer pinch-point and flying-metal risks.
• Better fleet value. Rental companies can offer one machine with several tools.
• Consistent fit. Once the coupler is on the stick, every compatible tool connects the same way.
• BHQC 40: for 1-4 ton excavators
• BHQC 80: for 4-8 ton excavators
• BHQC 150: for 12-16 ton excavators
• BHQC 200: for 18-25 ton excavators
• BHQC 250: for 25-30 ton excavators
Larger models use longer cylinder strokes and carry heavier attachments. Smaller models suit compact machines on tight job sites.
Does your machine weigh 8-12 ton? Send us the excavator model, and our team will advise the suitable option.
How to read the table:
• Excavator weight: the operating weight range the model is built for. Stay inside the range.
• Cylinder stroke: the travel of the locking cylinder. It increases with coupler size.
• Hydraulic flow: all models list 10-20 l/min. Check your auxiliary circuit against this figure.
Pin diameter and center distance decide whether a coupler really fits. Send us your stick and attachment pin dimensions, and we will confirm the match before you order.
A hydraulic quick hitch coupler works with many attachments, as long as pin sizes and spacing match. Common examples include:
• hydraulic breakers for concrete, rock and demolition work
• A digging bucket for trenching and general excavation
• A grab bucket for loading and handling loose or bulky material
• Other tools, such as hydraulic crushing pliers or a hydraulic peel grapple
Heavy attachments add load to the coupler. Always compare the combined weight of coupler and attachment with your excavator lifting capacity.
2. Stick-end pin. Measure the pin diameter and the width of the stick end.
3. Attachment pins. Measure pin diameter and center distance on every attachment you plan to use.
4. Hydraulic supply. Confirm the auxiliary line flow and hose connections.
5. Total weight. Add coupler and attachment weight, then compare it with the excavator rated capacity.
Do not choose by tonnage alone. Two excavators of the same weight can have different pin sizes.
• Stick-end pin diameter and width
• Pin diameter and center distance of each attachment
• Flow and pressure of the auxiliary hydraulic line
• Order quantity and destination port
With this information, we can recommend a model quickly and avoid costly fitment errors.
Neither type wins in every case. Choose hydraulic if your crew changes tools several times a day. Choose manual if changes are rare and budget is the main limit.
• Check valve: does it hold cylinder pressure if the hydraulic line fails?
• Secondary lock: is there a safety pin or latch as a second layer of protection?
• Pin retention: how does the design hold both the front and rear pins?
• In-cab control: is the switch clear and protected from accidental use?
• Operator manual: does the product ship with clear instructions?
Train every operator on the lock procedure, and keep the operator manual in the cab. Operators should always test the lock by pressing the attachment against the ground before lifting. Safety rules for quick couplers also differ by country, so check your local requirements before importing. Ask us to confirm the locking design of the model you order, and request drawings if you need them.
• Direct technical answers. Your engineer talks to the people who make the product.
• Specification control. We confirm dimensions against your machine before production.
• Transparent pricing. You deal with one supplier instead of several trading layers.
• Repeat-order consistency. Each shipment follows the same drawings and specifications.
• Easier project coordination. One supplier can quote couplers together with matching attachments.
Whichever supplier you choose, ask for drawings, material information, inspection records and product photos or video before you pay.
We supply customers across the Middle East and North Africa, including Saudi Arabia, the United Arab Emirates, Kuwait and Qatar. We also run a logistics management center in Riyadh, Saudi Arabia. Buyers in other regions are welcome to ask about shipping options.
Before you place an order, confirm these points with us:
• Trade terms, such as FOB or CIF
• Packing method for sea or air freight
• Production and delivery lead time
• Payment terms
• Export documents your customs office requires
Clear documentation helps avoid delays at customs.
1. Read the official documents.
2. Check the equipment for transport damage.
3. Prepare tools and a clean working area.
4. Fit the pins and connect the hydraulic hoses.
5. Cycle the cylinder several times to remove air, then test with a light attachment.
Regular maintenance keeps the coupler reliable:
• Grease pins and moving parts as the manual states.
• Inspect hoses and fittings for leaks.
• Check hooks, latches and pins for wear.
• Clear mud and debris from the locking area.
• Replace worn or damaged parts immediately.
Our BHQC series covers 1-30 ton excavators. If you need product details, a quotation, customization advice or technical support, contact our team with your excavator model and pin dimensions. We will reply with a recommended model.

Hydraulic vs Manual Quick Hitch Coupler: Which Is Better?
Both types hold an attachment on the stick. The difference is how you lock and release it.| Feature | Hydraulic Quick Hitch Coupler | Manual Quick Hitch Coupler |
| Locking method | Hydraulic cylinder | Mechanical lock tightened by hand |
| Operator position | Stays in the cab | Leaves the cab to lock and release |
| Change time | Short | Longer |
| Hydraulic connection | Required | Not required |
| Upfront cost | Higher | Lower |
| Best for | Frequent changes, rental fleets, mixed jobs | Occasional changes, tight budgets |
Neither type wins in every case. Choose hydraulic if your crew changes tools several times a day. Choose manual if changes are rare and budget is the main limit.
Hydraulic Quick Hitch Coupler Safety Features for Operators
A coupler holds a heavy attachment above people and equipment, so locking safety matters. When you compare suppliers, ask about these points:• Check valve: does it hold cylinder pressure if the hydraulic line fails?
• Secondary lock: is there a safety pin or latch as a second layer of protection?
• Pin retention: how does the design hold both the front and rear pins?
• In-cab control: is the switch clear and protected from accidental use?
• Operator manual: does the product ship with clear instructions?
Train every operator on the lock procedure, and keep the operator manual in the cab. Operators should always test the lock by pressing the attachment against the ground before lifting. Safety rules for quick couplers also differ by country, so check your local requirements before importing. Ask us to confirm the locking design of the model you order, and request drawings if you need them.
