Heavy Machinery

Matching Attachments to Carrier Weight and Hydraulics

Avoid equipment damage by verifying that your excavator or skid steer matches the weight and hydraulic requirements of the attachment. For example, heavy-duty scrap shears weighing 1,850 kg require a carrier weight of 20 to 28 tons to maintain stability and prevent tipping. Smaller attachments, like hydraulic earth augers, are rated for 1-3 ton mini excavators or skid steers.

Operating pressure and connection sizes must also align. Check auxiliary hydraulic configurations to ensure your carrier can handle the specific flow rates required by high-torque attachments.

• Check the hydraulic connection ports, such as 1/2 inch NPT, and hose lengths to ensure direct compatibility with your machine's auxiliary lines.
• Verify carrier operating weight limits before mounting heavy steel attachments to prevent hydraulic system strain.
• Match engine power ratings, ensuring your host vehicle can support the auxiliary hydraulic flow requirements.

Evaluating Material Processing and Output Requirements

Selecting mobile processing machinery requires matching feed size and throughput capacity to your project scale. For aggregate processing, a tracked portable jaw crusher handling a maximum feed size of 400 mm can output material ranging from 20 to 100 mm at a rate of 15 to 30 tonnes per hour. For deep foundation or exploration work, choose drilling rigs based on maximum depth capacities, such as full hydraulic diesel systems rated down to 500 meters.

• Assess hopper and silo capacities, such as a 3 cubic meter hopper for crushers or a 1-3 tonne cement silo for mobile mixers.
• Evaluate transport dimensions, such as 8.5 by 2.3 by 2.8 meters, to plan transport logistics and site access.
• Confirm engine power thresholds, typically 15 to 25 kW for compact mobile plants, to ensure sufficient onsite performance.

Selecting OEM-Compatible Replacement Parts and Hardware

Drivetrain and cabin components must match exact OEM part numbers to prevent premature wear or installation failures. Heavy equipment like skid steers relies on precise belt tensioner assemblies and pulleys to maintain system timing and power transfer. Always cross-reference your specific loader model, such as Bobcat S130 through S590 or T110, with verified replacement part numbers like 6711698 or 6689611.

• Use metal pulleys and tensioner assemblies rather than plastic alternatives in high-debris construction environments.
• Verify universal fits for cabin hardware, ensuring door locks and handles match standard configurations like the 502 Type metal lock.
