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.

What Are the Benefits of Interlocking Overhead Doors to Loading Dock Equipment?

If you have both a hydraulic dock leveler and an overhead door in the closed position and try to operate the dock leveler, the power of the dock leveler will damage the locked overhead door. If you have a vertical storing dock leveler in the rest (vertical) position and try and operate (lower) it when an overhead door is in the closed position, the dock will cause severe damage by impacting with the overhead door. In order to ensure that the dock leveler will not be able to operate when the overhead is in the closed position, you can equip the overhead door with an electronic interlock switch. Pit installed dock levelers or vertical storing dock levelers will only work if the overhead door is open.

Why Is There a Choice to Have Self-Contained or Remote Power Units for Dock Levelers?

Self-contained power units cost less and are the most common, however, there are alternatives. Remote power units are one of the alternatives and are best suited for wash down applications. When periodic maintenance is required, it is easier to access a remote power unit. At the time of installation, remote power units are typically installed 7’ – 8’above finished floor level on a wall mounting bracket. This moves the power unit up and away from potential impact. The hydraulic hoses are then run from the remote power unit to the dock leveler cylinder. Often the application determines the decision to go to a self-contained power unit or a remote power unit.

“Pentaflow Cylinders vs. Regular Cylinders”

Pentaflow lift cylinders are unique. In the base of the cylinder piston there is a port. This port is sealed by a ball to prevent oil from passing through. When oil is pumped into the cylinder, the cylinder extends. When the cylinder is at full extension, an actuator pushes the ball off the port which allows oil to return to the reservoir. This prevents the cylinder from dead ending. This also helps bleed any air inside of the hydraulic system. When the cylinder retracts, it siphons hydraulic oil into the top of the cylinder keeping all components of the cylinder lubricated.

Why Are There So Many Models Of Vehicle Restraints Available From A Single Manufacturer?

Not all applications are the same. In some cases, vehicle restraints are a part of the initial construction design process. It is also quite common to add vehicle restraints to an existing loading dock to improve the safety at this busy area of the facility. The positioning of the trailer’s rear impact guard can vary from trailer manufacturers. This has created the requirements for low profile vehicle restraints. Some facilities are able to cost justify mechanical vehicle restraints as an improvement over manual wheel chocks. There are many models to pick from and each design has its unique features.
