GOMACO’s Computerized Transition Adjuster
|
|
|
| GOMACO offers a patented computerized transition adjuster. The optional specialized computer control allows for smooth transitions from a crown to a flat cross slope in a superelevation, or vice versa. The computer controls and synchronizes the power transition adjuster (PTA) on the paver to make the necessary adjustments as specific stations are reached in the transition. |
|
|
|
|
|
GOMACO’s computerized transition adjuster is user-friendly and easy to understand. The PTA Status display allows the paver to monitor the transition count down, the target height of each PTA, current height of each PTA and paver travel speed per minute.
The transition count down displays the distance left 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. To start a transition, place the run mode to automatic and when the rear edge of the mold is in line with the starting point of the transition, press the “Start Transition” button. The “In Transition” button will then illuminate and display to the operator that the system is now in transition. |
|
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 eliminates the crown in the paving mold/slab or brings 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.
|
|

Auger/Strike-Off Mold
|
Open-Front Mold
|
|
| (1) The front split auger serves to spread the concrete to a predetermined width. The right-hand and left-hand drive sections are independently controlled with variable speeds.
(2) The strike-off is split for full, independent control. Both strike-off plates can be vertically controlled on the right and left sides, to meter material into the mold.
(3) The GOMACO grout box auger is for control of material through transitions or superelevations.
(4) Vibration is provided to the throat area of the mold for consolidation of concrete. The vibrators, with an automatic on/off control, activated with machine movement, are hydraulically powered with variable speeds up to 10,500 vpm. The vibrator positioning is hydraulically controlled for ease in start-up and finish.
(5) The GOMACO tamper bar system tamps down the aggregate even with the surface of the pan. The tamper bar is hydraulically powered with an automatic on/off control, activated with machine movement.
(6) The finishing pan serves to level the concrete. The 3100 series mold and stainless from front to back is 48 in. (1219 mm). The 5000 series mold and stainless is 60 in. (1524 mm) from front to back.
(7) Adjustable stainless steel is exclusive to the GOMACO system. This seals the surface and provides the troweled GOMACO finish out of the mold.
Molds Available for the GHP-2800

Detachable Auger/Strike-Off For Width Changes And Shipping
|
|
A 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 can then be broken down easily with removable and telescoping sections.
The auger/strike-off moves independently with hydraulically-adjustable mounts on the front of the mold. A self-supporting transition adjuster (TA) is standard to allow for crowning in the pavement.
Both the strike-off and auger have 6 ft. (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 ft. (3.66 m) wide on one truck. This design is based on a 5000 series open-front mold, allowing such molds to be retrofitted in the field.

|
Edge Slump Control From GOMACO
|
| GOMACO offers edge slump control to accommodate slump and mix design. Edge slump control is available in hydraulic or manual adjustments in the mold. |
|
Vertical Hinged Sideplates
|
| GOMACO’s Vertical Hinged Sideplates have hydraulic control for ease in start-up from an existing slab. The 4 in. (102 mm) cylinder stroke allows the split sideplates to open and close. This provides less labor and a smoother transition to the new slab. The Vertical Hinged Sideplates can be raised or lowered up to 19 in. (483 mm) to negotiate headers and other obstacles. The Vertical Hinged Sideplates are for four-track pavers only. |
|
Integral Curb
|
| A high-production feature on GOMACO slipform pavers is one-pass slipforming with integral curb on one or both sides of the slab. |

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 G21 digital controller 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.
