GOMACO Introduces the New GT-3400

GOMACO introduces its new GT-3400 three-track machine. It comes with some new and exciting features that put the GT-3400 in a class all by itself - it is the first curb and gutter machine to be controlled by remote control.

The GT-3400 features all-track steering. The new footprint features two close tracks on one side and a single track on the other for a tighter turning radius. The design also minimizes machine length.

The GT-3400's direct-drive trimmerhead is the most powerful on the market today. The radial piston hydraulic motor directly drives the trimmerhead. The trimmer's closed-loop hydraulic circuit and radial piston motor provide 27 280 ft lb of torque at the trimmerhead. The 610 mm diameter trimmer is equipped with Kennametal teeth, and the trimmer's width can be varied from 762 mm to 1981 mm.

The GT-3400 has a direct-drive, 356 mm diameter, charging auger to deliver concrete to the mold. The auger also hydraulically slides to help minimize the transport width. It slides down for hopper positioning and receiving concrete from the trucks and it slides up to reduce transport width.

Changing molds is quick and easy. The operator simply has to drive the GT-3400 up to the mold, hook the mount to a special attachment plate on the mold and lower the holddown. The operator then hydraulically lifts the mold and goes back to work slipforming the project.

The versatile GT-3400 is powered by a fuel-efficient 127 hp Caterpillar® engine with a remote mounted cooling package.

The GOMACO G21 and exclusive "smart" cylinders provide simple push-button steering setup on the GT-3400. The cylinders are attached to a new style of leg. GOMACO engineers have designed a new piston-style leg that acts like a cylinder. The legs have bearings on both ends of the inner tube so there is no steel-on-steel contact. A keyway is utilized for steering control and adjusting wear pads is a thing of the past with the new legs.

Two-speed track motors provide fast job-site mobility up to 38 m/min. It is one of the fastest tracking speeds in the industry.

The new GT-3400 has been designed to be a multi-application machine and will slipform right-side or left-side curb and gutter, tight radius, safety barrier, bridge parapet, sidewalk, recreational paths and flat slabs up to 1,8 m wide. Contractors can pave with either stringline or go stringless. The G21 controls interface with stringless technology/3D control systems.
