9500 trimmer

9500 Trimmer/Placer


Rideability Starts Here... With The World’s Most Versatile Material Handling Machine


The Advantage of GOMACO’s Unique Front-Mounted, Two-Track Design

• More Power and Minimum Side Clearance... Our state-of-the-art, hydrostatic, direct drive motor in the trimmerhead provides ample power for trimming capability and is mounted internally to allow minimal side-clearance.

• Does not Leave the End of the Pass Untrimmed... Only the front-mounted trimmer allows for trimming to the end of each pass or within inches of front obstacles.

• Low PSI... The large track surface contact area and the two-track design provide a high tractive effort and low ground pressure on the trimmed grade.

• Proportional Hydraulic System... Proportional valves are used in the conveyor lift and swing circuits, and the grade control circuit to provide fast, smooth responsive control.

• G+® Controlled Travel... Smooth travel for trimming accuracy and job-site mobility.

• Asset Utilization... The versatility of the 9500 comes directly from the frontmounted design. This allows changing the same machine from a grade trimmer to a shoulder trimmer or to a concrete placer.

• Less Maintenance Time... Easy access to the front-mounted trimmer allows quick inspection of the trimmerhead or replacement of teeth.

• Automatic Rear Steer... The 9500 features rear steer to back up on line with stringline or other guidance.

• Cruise Control To Maintain Constant, Maximum Production... The exclusive G+ control system on the 9500 has the GOMACO POS-A-TROL® feature for optimum performance and power to the trimmerhead. It will increase the operating speed to a predetermined level in relationship to the trimmer circuit pressure. The G+ control system automatically controls the travel speed through POS-A-TROL and takes the operator guesswork on “head pressure versus speed” out of the trimming operation.

• Quick Transport Readiness... The trimmerhead or concrete hopper is easily detached and the machine simply backs off. No additional equipment is needed at the location to remove them.

• It Loads Itself... Optional hydraulic front lifting arms load the trimmerhead onto the trailer, so additional heavy-lifting equipment is not needed at that location.

• Maneuverability... A 360-degree turn in the machine’s own length is possible because of the two-track design. A wide turning radius is not required like three-track machines. Maneuverability is important in today’s job-site conditions.

• Visibility Means Safety...The operator has a full view of the trimmerhead or concrete hopper because it is directly in front of the operator’s platform, or the operator can move around the platform using the exclusive GOMACO remote.

Versatility with Sonar, Front Lifting Arms, and Rolling Grade Ski

Grade sensing with GOMACO’s rolling grade ski is standard for the 9500. The versatile grade ski includes two rubber-tired casters which traces the existing grade or surface. The grade ski uses a standard sensor wand.

A digital tracking sonar sensing system is an option for the 9500 trimmer. This system is ideal for second pass trimming operations. Grade referencing is achieved as the sonar sensor bounces a sound wave off an existing slab or grade. No stringline setup is needed, and this saves time, which means more profit for the contractor.

Ease in loading the trimmerhead or receiving hopper onto a trailer for transport or positioning either of these attachments when mounting on the 9500 is achieved with the optional hydraulic front lifting arms at the front of the frame. The front lifting arms can lift the standard trimmerheads to a maximum height of 5.7 feet (1.74 m) and the mining trimmerheads to a maximum height of five feet (1.52 m).
