It is a steel post designed for temporary structural support, featuring an adjustable screw mechanism at the top for fine height adjustments and base plates at both ends for stability. The post is depicted in its extended form, highlighting its construction and components.

Constructed from 15-gauge prime steel tubing, the JP55 includes a 1-inch by 6-inch steel screw, two 4-inch by 4-inch by 10-gauge steel plates, a 7-inch turning handle, and both grooved and plain pins for adjustment. The entire unit is flow-coated with a red, corrosion-resistant paint for durability.

Informazioni sulla sicurezza

• Always ensure the jackpost is placed on a stable, level surface capable of supporting the intended load.
• Do not exceed the maximum load capacity of 14,000 lbs (at lowest extension).
• Wear appropriate personal protective equipment (PPE) during installation and adjustment.
• Ensure all pins are securely in place before applying load.
• This product is intended for temporary support only. Consult a structural engineer for permanent solutions.

Istruzioni di installazione

1. Disimballare i componenti: Carefully remove all components from the packaging. Verify that all parts are present: inner tubing, outer tubing, steel collar, steel screw, two 4x4 inch steel plates, 7-inch turning handle, grooved pin, and plain pin.
2. Assemble Base Plates: Place one 4x4 inch steel plate on the bottom of the outer tubing and the other on the top of the inner tubing. Note that these plates are designed to rest on the tubing and are not permanently attached, allowing for rotation during adjustment.
3. Position the Jackpost: Place the jackpost in the desired location, ensuring the base plate rests on a solid, level surface. The top plate should be positioned directly under the structural element requiring support.
4. Rough Height Adjustment: Extend the inner tubing from the outer tubing until the holes align at a height slightly below the required support level. Insert the grooved pin and plain pin through the aligned holes to secure this rough adjustment.
5. Regolazione fine dell'altezza: Insert the 7-inch turning handle into the hole on the steel screw at the top of the jackpost. Rotate the handle clockwise to extend the screw, gradually raising the top plate until it makes firm contact with the structural element and provides the necessary support.
6. Posizionamento sicuro: Ensure the jackpost is plumb (vertically straight) and stable. Re-check pin placement and screw tightness after initial load application.

Istruzioni per l'uso

The Marshall JP55 jackpost is designed for straightforward operation once properly set up.

• Adjusting Load: To increase support, turn the screw handle clockwise. To decrease support, turn it counter-clockwise. Make small adjustments to avoid sudden shifts in load.
• Capacità di carico: The maximum load capacity of 14,000 lbs is achieved when the jackpost is at its lowest extension (2 feet 10 inches). The load capacity decreases as the jackpost is extended to its maximum height (4 feet 7 inches). Always consider the load capacity relative to the extension height.
• Uso temporaneo: This jackpost is intended for temporary use. Regular inspection of the supported structure and the jackpost itself is recommended during its period of use.

Manutenzione

Proper maintenance ensures the longevity and safe operation of your Marshall JP55 Jackpost.

• Pulizia: Keep the jackpost clean from dirt, debris, and corrosive materials. Wipe down with a damp panno secondo necessità.
• Protezione dalla corrosione: The jackpost is flow-coated with red, corrosion-resistant paint. Inspect the paint regularly for chips or scratches. Touch up any damaged areas with a suitable rust-inhibiting paint to prevent corrosion.
• Lubrificazione: Periodically apply a light lubricant to the screw mechanism to ensure smooth operation and prevent seizing.
• Magazzinaggio: When not in use, store the jackpost in a dry environment to prevent rust and damage.

Risoluzione dei problemi

This section addresses common issues you might encounter with the Marshall JP55 Jackpost.

• Issue: Jackpost unstable or easily knocked over.

  Soluzione: Ensure the jackpost is under sufficient load. The top and bottom plates are designed to be unattached for rotational adjustment; they rely on the load to maintain stability. If not under load, handle with care to prevent the plates from dislodging. Always place on a firm, level surface.

• Issue: Difficulty turning the adjustment screw.

  Soluzione: The screw mechanism may be dry or have accumulated debris. Apply a penetrating lubricant to the screw threads and try again. Clean any visible debris. Ensure the jackpost is not excessively loaded or misaligned, which can bind the screw.
• Issue: Pins do not align for rough adjustment.

  Soluzione: Ensure the inner and outer tubes are clean and free of obstructions. Rotate the inner tube slightly while adjusting height to help align the pinholes. Do not force the pins.
