Detachable Auger/Strike-Off for Width Changes and Shipping
The 5000 series paving mold with a detachable telescoping auger/strike-off gives contractors the benefit of a mold that can be either an open front or an auger/strike-off . The optional detachable telescoping auger/strike-off provides easy width changes with the removable and telescoping sections. The auger/strike-off is independent and can be raised and lowered hydraulically. The strike-off features a center insert with a transition adjuster to allow for crowning. Both the strike-off and auger have six feet (1.83 m) of telescoping capabilities to aid in changing paving widths. When paving widths need to be changed, the contractor only has to add or remove a section of the paving mold and then telescope the auger and strike-off in or out, depending on the needed width. The telescoping auger incorporates bolt-on flighting to accommodate the changing widths. Along with giving the contractor some extra versatility on their pavers, the detachable telescoping auger/strike-off provides ease in transportation. The auger/strike-off can be detached from the front of the mold and the wings on the sideplates can be folded in to allow the paver, with the mold still mounted underneath it, to be transported under 12 feet (3.66 m) wide on one truck. This design is based on a 5000 series open-front mold, allowing such molds to be retrofi tted in the field.

GOMACO’s PTA, TBI, And SBI

Unparalleled Accuracy with the GOMACO Power Transition Adjuster (PTA)

GOMACO’s hydraulically-powered transition adjuster (PTA) provides on-the-go transitions in the crown of the concrete slab. A switch in the operator’s console controls the PTA in a positive or negative (up or down) motion. This flattens the crown in the paving mold/slab or adjusts the crown back into the mold/slab. These transitions are necessary in paving through superelevations and intersections.

This simple solution provides an easy method for an operator to perform a smooth transition where necessary and accomplish the required slab profile as specified.

 
 
Supported Power Transition Adjuster   A 5000 series mold with a self-supporting transition adjuster (TA). The self-supporting TA is available for widths up to 32 feet (9.75 m) on the 3100 and 5000 series molds, and up to 37 feet (11.28 m) on the 5400 series mold. This TA accommodates rear loading bar inserters.
 
 

GOMACO offers a patented computerized transition adjuster

The specialized GOMACO G+ accessory control system allows for programmed transitions from a crown to a flat cross slope in a superelevation, or vice versa. The G+ system is used to control the operations of up to four power transition adjusters (PTA), four tie bar inserters (TBI), two side bar inserters (SBI), a paint marker, and automatically timed spray bar.

GOMACO’s computerized transition adjuster is user-friendly and easy to understand. The PTA status display allows the operator to monitor the transition countdown, the target height of each PTA, current height of each PTA, and paver travel speed per minute.

The transition countdown displays the distance remaining in the current transition. The target height display shows the desired height of each PTA. The current height of each PTA is also shown along with a corresponding up and down arrow which is illuminated when the controller applies drive to each individual PTA.

The PTA setup display is easy to use as you simply enter the transition distance and the crown height that is required on the project.

This GOMACO G+ accessory controller also allows the operator to configure the software to insert side bars and tie bars to meet the particular job specifications.

 
 

The illustration above shows a stretch of roadway with a three inch (76 mm) crown to a zero (0) crown into a superelevation and out from zero (0) crown to a three inch (76 mm) crown. The operator has entered a minimum crown of zero (0) and a maximum crown of three inches (76 mm).

The transition computer automatically averages the distance of the two track lines, inside and outside of the slab, and calculates the total change from minimum to maximum crown over the total distance entered for the transition.

 

 

GOMACO’s Selective Steer Controls

Featuring Steering Choices for Job-Site Mobility and Transportability on Four-Track Pavers

GOMACO’s Selective Steer Controls feature forward/reverse steer and manual steering choices. The G+® controls feature control dials for manual steering and travel. The paver can be turned left or right with the G+ control steering dial as it is moved in the manual travel mode.

Stringline Steer Mode ... This mode is selected when steering is to be controlled by the steering sensors. The controller automatically recognizes where the sensors are plugged in and assigns steering, slope, or dual stringline to the appropriate tracks and display meters.
Coordinated Steer ... For minimum turning radius. When “coordinated steer” is selected, the steering control dial will control the turning of the tracks. If the dial is turned left or right from the center position, the leading tracks will turn in the corresponding direction and the trailing tracks will turn in the opposite direction.
Crab Steer ... The paver will walk sideways for ease in putting the machine on line. When “crab steer” is selected, the steering control dial will control the turning of all four tracks. If the dial is turned left or right, all tracks will turn in the corresponding direction to walk the machine to the side.
Front Steer ... When “front steer” is selected and the steering control dial is turned left or right, the front tracks will turn in the corresponding direction and the rear tracks will remain straight.
Rear Steer ... When “rear steer” is selected and the steering control dial is turned left or right, the rear tracks will turn in the corresponding direction and the front tracks will remain straight.
 
Counter-Rotation ... The unique counter-rotation programming allows the paver to turn 360 degrees within its own dimensions, providing excellent job-site maneuverability.

Only GOMACO Offers the Exclusive “Smart” Cylinders Featuring Push-Button Steering Control Setup on the Four-Track GHP-2800

Only GOMACO offers “smart” cylinders to aid in the setup and operation of the four-track paver, especially in minimum-clearance projects.

Steering control has been simplified with the exclusive “smart” cylinders, used for dependable steering control feedback, eliminating the sprocket, chain, and potentiometer at the top of each leg.

The “smart” cylinder reduces moving parts and eliminates the physical adjustments to the steering system.

GOMACO’s exclusive G+ control system makes it possible to have push-button steering setup. The “smart” cylinders can be taught the desired degree of leg rotation, so that the tracks do not strike any object in minimum-clearance requirements. The operator has the option of overriding this setting.

 

 

High Production and Serviceability are Key Factors on the GHP-2800

High production and serviceability are key factors of the GHP-2800. A fuel capacity of 125 gallons (473.2 L) combined with the engine's fuel efficiency provide an extended day of paving, resulting in higher production.

The segmented fiberglass shroud provides ease in serviceability. One section lifts up to allow access to the engine and service points. The battery box is located outside of the engine compartment for easier accessibility.

 
 
 
 
The GOMACO four track GHP-2800 is equipped with a 5400 series mold and Auto-Float to create the ultimate finish on a new roadway project.   This four-track GHP-2800 slipform paver is equipped with a side bar inserter (SBI) and an Auto-Float while working on a highway system.
 

 

Designed For Easy Transport

The GHP-2800 slipform paver is designed for easy transport. The two-track paver has a minimum transport width of 12 feet (3.66 m) and a transport length of 20 feet (6.1 m). The four-track paver has a minimum transport width of 8.2 feet (2.5 m) and a transport length of 36.9 feet (11.25 m). The transport height for the two-track machine with the mold attached is 11.2 feet (3.41 m) and the four-track machine with the mold attached is 11.1 feet (3.38 m). The minimum transport height without the mold is 10.2 feet (3.11 m) for the two-track and 10.1 feet (3.08 m) for the four-track.
 
 

 

Designed For Safety

The GP-2800 is carefully designed to give years of dependable and safe service. The emergency stop buttons are on the operator’s console and on the corners of the machine, which are easily accessible from the ground level. Another safety feature is a backup alarm, which is designed to alert personnel around the machine when the tracks are set to operate in reverse. Other safety features include track guards, warning decals, operator horn, an operator’s manual, and a safety manual. GOMACO machines are also designed to provide the operator with excellent visibility over the entire paving operation.
