Trencher: Good Practices

If you are starting a New dig job using a trencher, you surely know all about safety digging a trench. Many countries in fact have “guidelines” on excavations and safety initiatives.

The good practices you find here can be used as reminders or suggestions for optimal use of a trencher.
First of all, we are talking about excavation, and trenchers are the best tools for this type of work . Your experience is our job, and at MachinesBroker you can find everything you need to get your job done.

Let’s start with our guidelines, and see the three steps for perfect trench work: <! – more ->
Pre-trench. It’s all up to the project. A perfect design ensures that the jobs are executed perfectly . You have to check several things before you start digging a trench, from soil to underground utilities. You must make sure of every detail about security and provide secure access . Excavations in general are classified in two ways. First of all for the type of material excavated, then for the purpose of the excavation itself. When the classification is made for the type of material it is very important that the material is accurately identified to keep costs down and to avoid technical problems. Engineers and surveyors use various classification methods to measure how easy or difficult an excavation is. Four general categories are: a) easy , soft ground or sand, b) medium , clay c) medium-hard rocks, d) hard, materials that require explosives. What about trenchers? The machine assigned to the job must be suitable for the type of project. Using a machine that is too small will limit production or be damaged. A trencher that is too large may not be able to work in a confined space.

Excavation. You have created a secure access, you can start excavation . Adequate planning, having highlighted the underground utilities are essential for a successful excavation and installation of cables or pipes. Trencher workers must verify that all facilities are identified, the site must be carefully inspected, machine fluid levels checked and any signs of necessary maintenance. The operator must be prepared for all emergency intervention , he must be able to stop the machine if something goes wrong and restart if necessary. If the pre-excavation work has been done correctly, the excavation itself will be quick and clean. An important issue is the stability of the soil , appropriate measures must be taken to keep it stable and avoid any falls. If necessary, provide safety barriers. For a clean job it is also important to remove debris and excavated material (many Trenchers have conveyor belts to help you with this part of the job).
After the excavation work . The work is done, now what? Provide safe access for workers, ensure stability, install pipes and cables , repair existing damage. All excavation equipment requires regular daily maintenance which must be done at the end of a working day or before operating the machine again. Primary wear parts on any trencher are: chain, teeth, and digging sprockets. All fluids and filters should be changed at prescribed intervals , more frequently when operating in adverse or “dusty” conditions. L lubricate all service points and check the hydraulic system at intervals prescribed by the manufacturer . Adjust the drive belt or chain as needed and replace all guards and shields after completing other maintenance procedures.
