The line striper must be capable of spraying 5 guns at one time consisting of two colors. The line striper should have at least 2 pressurized bead guns along with a video display system used to accurately conduct line striping. The paint striping system should be modular so that options can be added or removed as needed. The line striper will need to have new operator training along with in person instruction on how to install and operate the piece of equipment. The delivery location is 74485 National Park Drive, Twentynine Palms CA, 92277.

1.2 Background

Joshua Tree National Park has a requirement to stripe park roads on a periodic basis. Over the course of the COVID pandemic it was discovered that the park did not have the required equipment or staff capable of conducting line striping when contracting is not available. To reduce costs and lessen the need to contract; park staff require a palletized line striper capable of spraying double yellow striping with black contrast line as well as white edge line.

1.3 Objective

The objective of the contract is to provide Joshua Tree National Park Road’s staff with a palletized line striper capable of spraying dual color with up to 5 guns operating simultaneously. The equipment specifications are based on a Graco Roadlazer Road Pak HD System Option HD4. All units submitted in bidding must be equal to or better than the below specifications and is not required to be a Graco brand road striper. The contractor will also be required to provide delivery, install, and training either in the park or at a location that is within 300 miles of Twentynine Palms CA.
