Frequently asked questions

Common questions about CHIEF from 3G Electric.

What are the common mounting styles available for CHIEF welded hydraulic cylinders?

CHIEF welded hydraulic cylinders are available with cross-tube and clevis mounts. Cross-tube mount cylinders, such as SKU 833A87 and SKU 833AP9, feature a cross tube welded to the cylinder for pivot mounting. Clevis mount cylinders, like SKU 833C16, have a clevis bracket at the rod end or cap end for pin connection. These mounting styles are suitable for different applications: cross-tube mounts are often used in mobile equipment where the cylinder pivots on a tube, while clevis mounts provide a more traditional pin connection. Both styles are double-acting and come in various bore sizes and stroke lengths to match specific force and travel requirements.

What is the maximum pressure rating for CHIEF DC hydraulic power units?

CHIEF DC hydraulic power units, such as the model with MPN 253343, have a maximum pressure rating of 2,800 psi. This unit delivers 1.2 gpm at 12V DC and features a 6-quart poly reservoir with SAE 6 ports. The pressure rating indicates the highest continuous operating pressure the unit is designed to withstand. When selecting a power unit, ensure that the system's relief valve setting does not exceed this rating. The 12V DC operation makes it suitable for mobile applications where battery power is available. For other models, refer to the specific datasheet for pressure ratings and flow characteristics.

How do CHIEF rephasing tie-rod cylinders work in multi-cylinder systems?

CHIEF rephasing tie-rod cylinders, such as those in the 833AG series, are designed to maintain synchronization in multi-cylinder circuits. They feature a rephasing port that allows fluid to bypass when the cylinder reaches the end of its stroke, ensuring all cylinders in the system fully extend or retract together. This is critical in applications like dump trailers or lifting platforms where uneven movement could cause structural stress. The cylinders have a tie-rod construction for durability and are available with bore diameters from 3 1/4 to 3 3/4 inches and stroke lengths from 8 to 12 inches. Port sizes are #8 SAE, and rod diameters range from 1 1/4 to 1 3/8 inches.

What is the purpose of a CHIEF hydraulic cylinder stroke control?

A CHIEF hydraulic cylinder stroke control, such as SKU 833XU6, is used to limit or adjust the piston travel distance in a hydraulic cylinder. It is installed on the cylinder rod and acts as a mechanical stop, preventing the rod from extending or retracting beyond a set point. This is useful in applications where the full stroke of the cylinder is not needed, or where the stroke must be precisely controlled to avoid damage to the equipment or workpiece. The stroke control has female 1-1/4 inch and male 1-3/4 inch thread connections and weighs 3 pounds. It is suitable for industrial machinery and mobile equipment where adjustable stroke limitation is required.

What bore sizes and stroke lengths are available for CHIEF welded hydraulic cylinders?

CHIEF welded hydraulic cylinders are available in a range of bore sizes and stroke lengths to suit various applications. From the sample products, bore diameters include 2 inches, 3 inches, and 8 inches, with stroke lengths of 10 inches, 30 inches, and 36 inches respectively. Capacities range from 9,420 lb to 150,790 lb. Retracted lengths vary accordingly, such as 17 inches for the 2-inch bore model and 52 inches for the 8-inch bore model. These cylinders are double-acting and can be specified with cross-tube or clevis mounts. For a complete list of available sizes, consult the product datasheets or contact 3G Electric for assistance.
