RTP-500 Placing Conveyor Provides High-Production Results
High-production results are achieved with the versatility of the long placing conveyor.
The conveyor is 35 feet (10.67 m) long and 36 inches (914 mm) wide, with 170 degree hydraulic swing, and 12 feet (3.66 m) of hydraulic elevation adjustment.
The placing conveyor allows for fast and accurate material placement from the haul road, over the stringline or other obstacles, and reaches across the grade. The conveyor deflector directs the flow of concrete at the discharge end of the conveyor.
The auger-style receiving hopper is 10.75 feet (3.28 m) wide, and has a working capacity of 4.75 yd3 (3.63 m3). It’s built with the strength and durability for handling high-volume throughput for end-dump paving operations. The hopper features a 12 inch (305 mm) hydraulic vertical adjustment to allow for variable gate height on dump trucks. A 14 inch (356 mm) diameter auger with split flighting and speeds up to 88 rpm quickly moves the material to the transfer conveyor. Shaft-mounted eccentric vibrators provide vibration for emptying the hopper after each load and increased flowability. The hopper/truck seal is supported by a hydraulically tensioned cable for consistent sealing on a wide variety of dump truck bodies. The 36 inch (914 m) wide, 16.6 foot (5.06 m) long transfer conveyor moves material to the rear placing conveyor at speeds up to 608 feet per minute (185 mpm). Both conveyors are activated with a single switch and have individual speed controls.
The hopper features a 12 inch (305 mm) hydraulic vertical adjustment to allow for variable gate height on dump trucks. The hopper/truck seal moves out for additional cleaning.
The step on the side of the hopper provides a spot for the truck control coordinator to monitor the hopper as concrete is dumped, along with being able to guide the trucks as they back into position for the RTP-500. The hopper remote control allows the truck control coordinator to raise and lower the hopper, turn the vibrators on or off, adjust the variable gate height, operate the hitch lock, and turn the high-pressure water on or off.
A flat-panel 6.5 inch (165 mm) anti-glare display screen is provided with sensor-controlled backlight levels for superior visibility in all operating conditions. The screen is rugged and shock resistant in its construction to protect against dust, moisture, and rain. G+ provides a full color display on the control panel to illustrate the various aspects of the placer operation. Newly designed icons and color graphics make it easy to understand and identify the targeted functions. G+ controls feature a detailed fault history with the time stamp, date, and information to track when each fault occurred. GOMACO’s G+ control system has been proven around the world.
Console Positioning Versatility
The operator’s platform provides a panoramic view of the entire operation. The console and chair roll from left to right on the platform to provide more comfort and visibility for the operator. The versatile console can be set at five different positions. It can be positioned straight forward or turned 90 degrees to the left or right.
The GOMACO RTP-500, powered by a John Deere 6068H turbocharged diesel engine, has fast job-site mobility, with a travel speed up to seven miles per hour (11 kph), and an operating speed up to 110 feet per minute (33.5 mpm). The rubber tracks can go where rubber tires don’t dare.
The hydraulically folding rear conveyor minimizes the transport requirements on the RTP-500. The overall shipping length is 37.25 feet (11.35 m), width is 11.8 feet (3.6 m) with the hopper attached, 10.3 feet (3.14 m) without the hopper, and a height of 11.7 feet (3.57 m) with the conveyor folded.
GOMACO’s RTP-500 rubber-tracked placer provides more versatility by being able to place a variety of materials for different applications.
The conveyor must be centered and folded before G+® controls will allow for travel speed. There is no counter rotation of tracks in the travel speed. The steering sensitivity is programmed to provide balanced steering control at low or high speeds, preventing the operator from oversteering at high speeds. Five emergency stop (E-stop) buttons are located on strategic areas of the machine. G+ features control interlocks to prevent unexpected movements at start-up. The RTP-500 has many other safety features, including a flashing light on the end of the conveyor, a belt swing alarm, back-up alarm, operator horn, and the hopper remote control.
