Crawler Excavators

DEVELON -7 Series crawler excavators deliver the powerful arm and bucket forces needed on rugged construction and infrastructure projects for digging into tough materials or lifting and loading heavy materials. The counterweight adds stability when using heavier attachments. Select the one-touch power boost to amplify hydraulic power for more difficult digging tasks. A strong, productive swing torque allows the excavator to swing uphill with ease — improving backfilling performance. Fast cycle times help you complete work quickly and efficiently so you can move on to the next challenge.

Selectable power modes help you balance fuel consumption and machine power based on your working conditions. Choose from:
Power+ mode delivers faster workgroup speeds and greater productivity during harsh conditions.
Power mode provides excellent power and superior performance for tough digging and heavy lifting.
Standard power mode optimizes fuel consumption and delivers high performance for everyday working conditions.
Economy mode reduces fuel consumption for low-demand applications.

A fine swing function provides greater control and accuracy in certain lifting conditions, minimizing the shaking of a lifted object.

The optional intelligent floating boom offers two settings that allow the boom to move freely with the contours of the ground. In full float setting, the boom is allowed to rise and fall as required while the bucket moves across the ground — ideal for finishing work and truck loading. With the hydraulic breaker setting, the boom moves down freely under its own weight to reduce shock and vibration for longer breaker service life.

Standard and long arm configurations are available, depending on the model. Select models are available with super-long reach or mass-excavation arm configurations. All include a heavy-duty front design with additional reinforcement on key stress points.

This optional feature is beneficial for straight forward and backward travel, which is ideal in trenching applications and transportation. A single foot pedal controls both tracks.

A crawler excavator is a type of heavy construction equipment designed with a set of tracks instead of wheels, which enables it to move on rough and uneven terrain. The excavator tracks also provide excellent stability and traction when working in soft soil conditions. Crawler excavator uses include trench digging, excavating and lifting.  

Choosing a crawler excavator involves considering a variety of factors. These factors include project requirements (digging depth, reach and lifting capacity), excavator size, attachments, operating environment and ground conditions.  

Crawler excavator prices and rental costs vary based on the local market, machine class and options. DEVELON suggests that you  identify your required equipment specs and consider the available space at the job site. This will help you narrow down the options and choose an excavator that provides the performance and capabilities for you to work efficiently.

The maximum digging depth of a crawler excavator varies based on the model and size of the excavator. The digging depth depends on factors like boom length, arm length and whether there is a bucket or other attachment. DEVELON crawler excavators offer dig depths from approximately 20 to 30 feet, depending on the machine configuration. You can typically find these equipment specifications on the manufacturer's website, on the excavator model pages.

The maximum weight a crawler excavator can lift, also known as lifting capacity, varies based on the model and size of the excavator. Add-ons, such as an excavator counterweight, can increase the machine’s lifting capacity. DEVELON recommends reviewing the excavator lifting capacity chart in the Operation & Maintenance Manual before lifting any objects.

Maintenance requirements for a crawler excavator include the following: inspecting daily, checking fluids, replacing filters, greasing lubrication points, maintaining proper track tension, cleaning the cooling system and checking the electrical and hydraulic systems. An excavator maintenance checklist is a good method for tracking machine upkeep. Make excavator repairs immediately to avoid machine downtime. Use MY DEVELON fleet management to stay on top of machine maintenance.

DEVELON crawler excavators feature hydraulic systems designed for peak performance and efficiency across various applications. These systems respond to the operator’s demand by controlling the auxiliary hydraulic pump’s flow output based on load sensing. As a result, the correct amount of flow is delivered to each function, ensuring efficient completion of the job.

A wide range of attachments is available for crawler excavators. Among the most common attachments are buckets for everyday excavating tasks. A hydraulic quick coupler is a popular option for changing attachments. Thumbs are regularly paired with buckets to grab, lift and discard materials.

Safety features for crawler excavators include a standard rearview camera and optional equipment such as a side view camera, LED lights and around view monitor (AVM) camera system. Operating a crawler excavator safely requires proper training, adhering to safety guidelines and using the machine responsibly. Basic safety measures include conducting a thorough pre-operation inspection to identify any issues before starting work. Always wearing a seat belt. Positioning the excavator on stable and level ground. Clearing the work area of any debris and hazards that could interfere with the excavator’s movement. And finally, keeping a safe distance from the edge of the trenches.
