This GOMACO 3300 is equipped with a sideshifting trimmerhead and curb mold. The 3300 features the smart telescoping mold mounting system with feedback to the G+ controls for repeatable mold off set. The mold and trimmer can be hydraulically lifted over obstacles found on the job site.

 

 

A 20 foot (6.1 m) folding conveyor to load the hopper is available on the GOMACO 3300. The conveyor can be positioned for either right-side or left-side slipforming. The conveyor folds to reduce the transport length of the paver.

 

 

 

The charging auger on the 3300 is equipped with vibration to release concrete build up from the safety guard at the end of the hopper. The auger’s safety guards are hinged to allow for cleaning.

 

 

The GOMACO 3300 is designed for right-side and left-side pours. The U-shaped operator’s platform and sliding console allow for optimum visibility and control to pave in either direction.

 

 

 

 

The two front legs are mounted on
parallelogram-style pivot arms.

 

 

Xtreme Design
Extreme steering capabilities are standard on the 3300 with rotary-sensored slew drives on each track. The two front legs are mounted on parallelogram-style pivot arms allowing for adjustments out from the right side and left side of the machine. The rear power-slide leg can be positioned to the right or left of center. The front leg pivot arms and power-slide on the rear leg allow for correct positioning feedback through G+® control. Smart leg positioning and smart steering provide the 3300 with correct steering angles through a radius.

 

Xtreme Hydraulic Package
Independent hydraulic travel control to each track allows G+ to control the individual track’s speed through a radius.

 

Xtreme Steering Capabilities
The 3300 is equipped with rotary-sensored slew drives on each of the three tracks for extreme steering. The extreme steering capabilities, combined with the 3300’s sensored All-Track Steering and sensored All-Track Positioning, make it the ultimate intelligent slipform paver. The intelligent All-Track Positioning on the 3300 includes a smart hydraulic cylinder on each of the three legs. The smart cylinders allow G+ control to know the position of all three tracks to make steering adjustments as needed.

 

Xtreme Radius
The GOMACO 3300 can pour a 24 inch (610 mm) radius. The 3300 G+® control system easily interfaces with stringline or a 3D guidance system for curb and gutter and tight radius applications. The 3300 features the GOMACO three-sensor radius system for stringline. When paving with stringline, the lead steering wand is allowed to leave the stringline and reference is switched to sensor number two for traveling around the tight radius. Individual track speed control provides smooth machine travel around the radius.

 

G+ Radius Software For Stringline Operation
Choose your radius and G+ calibrates and manages all aspects of traveling around the radius, including track angles and individual variable track speeds. The G+ radius software for the control system allows the operator to program the size of the radius into the controller. As the 3300 approaches the radius, with the values already dialed in, the operator activates the radius program, and the curb and gutter machine slipforms around the radius.

 

Xtreme Intelligence
Smart cylinder sideshifting of the mold provides G+ the ability for repeatable mold off set. Intelligent off set is accomplished with a smart hydraulic cylinder for telescoping the mold mounting system. The trimmerhead and mold have independent vertical adjustments allowing each to raise and lower separately.

 

 

Each track is equipped with rotary-sensored slew drives for extreme steering. The conveyor has four-way hydraulic positioning which is located between the two front legs. The four-way positioning cylinders provide pivoting tilt, pivoting swing, longitudinal slide, and sideshifting of the conveyor.

 

 

A 3300 slipforms curb and gutter on the right side with 3D machine guidance. Right-side slipforming is beneficial to contractors because it allows the concrete trucks to drive ahead of the paver and easily back up to deliver the concrete without disrupting the flow of traffic.

 

 

 

The GOMACO 3300 features the power-slide rear leg to position the leg for weight distribution.

 

 

The hydraulic sideshift and lift on the 3300 allows the mold to easily slipform curb and gutter below the existing grade on rehab projects.

 

 

Hook & Go
GOMACO’s Hook-and-Go mold mount system has no pins or latches and makes it quick and easy to change molds. Simply drive the 3300 up to the mold and hook the mount to a special attachment plate. The mold is then hydraulically lifted up and can go to work slipforming the project... just hook and go. Tight-clearance paving is accomplished with the sideshifting capability of the mold on the GOMACO 3300.

 

Repeatable Mold Offset
The 3300 features intelligent off set which is accomplished with smart hydraulic cylinders for telescoping the mold mounting system. This provides G+ the ability for repeatable mold off set. The mold can be hydraulically lifted over obstacles found on a job site. The GOMACO 3300 also features All-Track Steering (ATS) allowing the 3300 to slipform tight radius work and allows the machine to move easily around the job site. ATS saves time getting on and off stringline, job-site mobility, and loading and unloading for transport. The ability to steer all of the tracks allows accurate steering around tight radii.

 

Trimmer & Trimming Power
The GOMACO 3300 slipform paver features a sideshifting and vertical adjusting trimmerhead and mold. The trimmerhead has a maximum hydraulic sideshift distance of 48 inches (1219 mm) and an 18 inch (457 mm) hydraulic vertical adjustment for slipforming right up to the obstacle before lifting up to go over the obstacle to continue paving. The trimmerhead is directly driven with a radial piston hydraulic motor which provides maximum torque for trimming capacity.

 

Fast Loading Provides Increased Production
Fast concrete loading provides high-production results. There are two concrete delivery systems to choose from with the GOMACO 3300, the charging auger and the folding conveyor. The 17 foot (5.18 m) long, 16 inch (406 mm) diameter charging auger provides fast and efficient concrete flow with an auger speed variable up to 88 rpm. The charging auger features vibration at the end of the hopper allowing concrete build-up to be released. The vibration is manually activated by the ground personnel.

The conveyor is 20 feet (6.1 m) long, 24 inches (610 mm) wide, and has a belt speed variable up to 254 feet per minute (77.4 mpm). It is hydraulically powered and reversible with a charging hopper. The conveyor is pivot mounted with hydraulic lift and positioning. The mold is designed with extra concrete capacity, to allow slipforming through a tight radius without waiting for concrete truck repositioning.

 

The folding conveyor features four-way hydraulic positioning for optimum concrete delivery and placement.
