Applications
Primary Vehicle Applications
Standard Dump Trucks (Class 7 & Class 8): Widely used on 10-wheelers, tri-axle, and quad-axle dump trucks with body lengths ranging from 14 to 18 feet .
Dump Trailers & End Dumps: Installed on medium-sized end dump semi-trailers or heavy-duty pull trailers requiring an aggressive tilt angle to shed stubborn
Pup Trailers: Commonly used on independent dump pup trailers towered behind a standard dump truck to maximize total hauling capacity.
Construction & Aggregates: Lifting heavy loads of gravel, crushed stone, sand, and asphalt on rugged construction sites.
Demolition & Waste Management: Tipping large-volume truck bodies carrying concrete debris, scrap metal, and heavy municipal waste .
Mining & Earthmoving: Operating on site-specific support vehicles hauling heavy soil, overburden, and mineral ores .
Agriculture: Used on specialized agricultural bulk trailers for high-volume dumping of grain, silage, and fertilizers .
4 Bore × 12 Stroke Ag Clevis Hydraulic Cylinders are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
The thrust and pull of a hydraulic cylinder depend only on the system working pressure and the cylinder's pressure-bearing area (determined by the cylinder diameter and rod diameter) , and are independent of the stroke (length).
At 2500 PSI pressure, both have a maximum theoretical thrust of 31,416 pounds (approximately 14.2 tons) . The 12-inch stroke simply means it can hold that force and move it a longer distance (2 inches more).
As the stroke length increases, the bending stress (column load) experienced by the cylinder when it is fully extended (total length 34.25 inches) will increase.
If your application involves significant resistance or may experience slight angular misalignment, it is recommended to prioritize the welded model with a 1.75-inch heavy-duty piston rod (3000 PSI level) , which offers better bending and impact resistance than the standard 1.5-inch piston rod.
22.25 inches (approximately 565 mm) is the rigid physical limit from center to center of the pin holes at both ends ; the cylinder cannot be shortened further.
If your mechanical mounting point is less than 22.25 inches when fully retracted, the cylinder cannot be installed; forcing it will cause the mechanical structure to jam or damage the cylinder. If the mounting point is slightly larger, it can be installed, but the cylinder may not be able to fully retract to the intended mechanical position.
Most double-eared hydraulic cylinders marked "Ag (Agricultural)" lack a deceleration buffer at the end of the stroke in pursuit of cost-effectiveness and compact structure. When the piston reaches its full speed at the 12-inch end point, a hard impact occurs directly between the metal parts.
Solution: When operating a hydraulic multi-way valve, it is recommended to fine-tune the valve stem (partially open the valve) before the cylinder reaches its end point to reduce the flow rate and allow the cylinder to slow down and land softly. This can significantly extend the life of the cylinder and mechanical mounting points.
The cylinder requires approximately 0.65 gallons (about 2.46 liters) of hydraulic oil to fully fill and extend.
Recommended flow rate: With a hydraulic pump of 5 to 8 GPM , it takes approximately 5 to 8 seconds for the cylinder to fully extend once. If the flow rate is too low (e.g., less than 2 GPM), the action will be too slow; if the flow rate is too high (e.g., more than 15 GPM), it will cause excessive hydraulic shock and a rapid increase in oil temperature.
