What Is An FRL On An Air Operated Lift Table?

FRL stands for Filter Regulator and Lubricator. In some applications, depending on vertical travel, an air bag lift table will not be suitable. The alternative is a hydraulic lift table with an air motor operated power unit. It requires compressed air to operate this motor and there are some maintenance factors to maintain efficient operation of the motor. These components are often referred to as an FRL. F – Filter: compressed air that has a high moisture content which is best to remove before it is pumped to the air motor. That’s the function of the filter. R – Regulator: the regulator is in the system to regulate and maintain the PSI rating (pounds per square inch) to efficiently operate the air lift motor. L-Lubricator: the filter removes the moisture from the compressed air and the lubricator adjusts and meters a quantity of lubrication into the compressed air. This process happens before the compressed air reaches the air motor. This light lubrication maintains the efficiency of the air motor operation.

When Do You Choose A Dock Lift Instead Of A Dock Leveler?

Dock lifts are generally used if you don’t have a conventional 4 foot high loading dock area. A dock lift would be used to get product from a truck to ground level or vice versa. In multiple dock positions, something that is becoming more common is the use of a dock lift. While dock levelers will handle the conventional trucks, in addition to conventional trucks a dock lift can accommodate any incoming truck bed height (FedEx, UPS, etc.). Dock lifts can also be used to store property maintenance equipment in the offseason. Common applications for a dock lift are institutions, retail outlets, universities, hospitals, etc. If the decision is to go with a dock lift, you can select from a pit installed model or a surface installed (no pit required). Often the application dictates the most appropriate product to select.

Why Does It Cost More To Paint A Colour That Is Not Company Standard?

All manufacturers have a standard paint colour that is for brand identity or for economy of scale in any high volume manufacturing facility. Pretty much any colour other than the manufacturer’s standard is available, but at an upcharge. The reason for this upcharge is due to the purchasing process, receiving process and manufacturing process. Depending on the colour of the paint, primer may need to be added to the lift table before the paint is applied. When painting a lift table a custom colour, the painter must first clean the lines with xylene. The painter then must pour primer into the paint gun reservoir and apply the primer to the table. Once the painter finishes applying the primer, the painter then takes the primer out of the paint gun reservoir and cleans the lines with xylene again. The painter must then put the custom colour paint into the paint gun reservoir, apply the paint to the lift table, and clear the lines for the last time. Depending on what paint a company chooses, the lift table may need to be specially packaged before it is shipped to the customer. Most manufactures require a RAL number of the colour requested to assure that the paint colour is exactly as ordered.

Why Are There So Many Horse Power Ratings For Lift Tables?

The reason lift tables have various horse power ratings is strictly to achieve typical speeds of vertical travel. The quicker the oil can be pumped into a cylinder, the quicker the cylinder extends, increasing the lift speed. Generally, the higher the capacity of the lift table, the more cylinders the lift table will require. In order to maintain typical lift speeds of 10 – 12 feet per minute, a higher rated power unit is used to achieve these speeds.
