Match the machine to the work
Compare PC300, PC350 and PC360 when road cuts and high-volume excavation require more production than a 20-ton machine.
PC400 and PC450 are stronger candidates for heavy loading and quarry support, subject to material, bucket and site conditions.
Confirm machine dimensions, loading method, site access, parts plan and attachment before choosing the largest available unit.
Evidence before payment
Model name and listed price narrow the choice. The final decision should use evidence from the exact serial-numbered machine.

The current PC300 machine reference price is displayed on its stock card. Final Guyana cost is confirmed after the exact machine, inspection scope and destination are selected.
Compare the exact condition and quotation first because both target similar heavy work. Choose the unit with the stronger inspection result and better project fit, not only the lower price.
Choose PC450 only when its additional production is required and the project can support the larger transport, operating and maintenance commitment. Otherwise PC400 is the more controlled decision.
Confirm cold start, engine load response, hydraulics, boom and arm play, swing, travel, undercarriage wear, leakage, serial information and the exact bucket or attachment.
Yes. Send the exact model, quantity, attachment and destination so loading and freight can be quoted without guessing.
