GM4 Crawler

Drainage channels, drainage systems or pitch heating for football stadiums - the trench cutter Grabenmeister GM4 Crwaler is an all-rounder

Versatile in use, even in hot, rough or mountainous regions, this modern trench cutter for drainage channels is the reliable tool when it comes to trench excavation or canals. Equipped with an all-terrain four-wheel drive, the tracked version offers even more safety, precise driving comfort and optimum load distribution. The trench cutter GM4 Crwaler for drainage channels feels at home at the edge of the field, where a drainage channel is planned. But also on the football pitch, where it mills the channels for the pitch heating - without ruining the lawn.

The technically mature equipment of the Grabenmeister GM4 caterpillar for drainage channels

An economical but very lively 4-cylinder diesel engine ensures propulsion and sufficient power on the milling chain. Therefore, even heavy loamy soils or muddy terrain are hardly a challenge for this flexible machine. The excavated material is ejected to the desired side. A conveyor belt can also be used to dispose of it directly on an escort vehicle, which you can rent together with the trench cutting machine. The optional hopper on the GM4 crawler saves time. In one step the trench is milled and immediately filled with gravel. At the same time, the drainage pipe can be laid over a reel with pipe guide. This ensures the optimum position of the drainage in the sewer and three operations are carried out in one go. The sole scraper with metal sheets and the dozer blade are also part of the complex scope of supply.

Special advantages of the GM4 with caterpillar drive

For better road clearance, the landing gear lintel was designed to compensate for coarser unevenness in the ground. Compared to the wheel drive, the tracked version of the trench cutting machine has considerable advantages. This includes in particular the even weight distribution of the machine. The 4,900 kilograms cause only minimal damage with a chain, which is why the crawler is indispensable, for example, when used on sports grounds. For this reason, the GM4 crawler trench cutting machine is available for hire with operating personnel.

The GM4 crawler trencher for drainage channels can be used on chains on slopes without any problems. The vertical adjustment provides additional stability. The intelligent tilt device compensates for lateral inclines of up to 12° with the aid of powerful hydraulics. The adjustable operator's platform is advantageous for difficult applications. It can be moved to the left and far forwards, giving the operator a direct view of the milling chain and the trench.

As a crawler, the Grabenmeister GM 4 can cope with a wide range of requirements. The flexible machine can be set to milling depths of 600, 800, 1250 and 1500 mm. Milling chains with knife carbon bits or mixed chains are available. Milling widths from 70 to a maximum of 450 mm are possible.

Additional equipment for the trench cutter GM4 Crawler for dranaige channels

The basic version of the GM4 is designed as an open riding unit. In this version you can also rent these trenchers. The model is also available either with all-wheel drive or powerful crawler drive. As an option, a driver's cab can be fitted as weather protection. This is always equipped with a particularly comfortable driver's seat. If the mobile milling machine is purchased for year-round use, the installation of the heating is recommended. The Grabenmeister is almost luxurious, but indispensable in hot countries, and is also available with an air conditioning system for the driver's cab.
