The hydraulic system of a used excavator accounts for the bulk of the machine's value. A wrong selection or inadequate maintenance can eat up the profit of an entire machine in repair costs. Starting with mainstream hydraulic pump models such as Kawasaki, Rexroth, and Toshiba, this article provides selection criteria, price ranges, and common fault diagnosis methods for used pumps and valves. It also summarizes hydraulic oil change intervals, multi-way valve cleaning points, and precau

There is no standard formula for valuing used construction equipment, but there is an industry-standard breakdown method. This article starts from three dimensions—machine condition, hour meter, and brand value retention—and combines real transaction ranges for used excavators, used wheel loaders, and used bulldozers to provide an actionable pricing process and bargaining basis. It also covers valuation differences in mining truck and construction equipment export scenarios, helping bu

This article is aimed at buyers of used construction machinery. It systematically explains how to interpret the five major modules in an inspection report—engine, hydraulics, undercarriage, structural components, and electrical systems—and provides price references for used excavators in East China, South China, and Southwest China. It also summarizes a ten-step on-site inspection process and common pitfalls, with an FAQ addressing high-frequency questions such as the authority of insp

Incorrect selection or improper maintenance of hydraulic parts can lead to slow operation and engine stall at best, or scratched plungers and burned motors at worst. This article is aimed at used excavator users and export traders. It explains the selection parameters and matching principles of hydraulic pumps, motors, and multi-way valves, provides common troubleshooting procedures, overhaul intervals, and 2024 mainstream model parts price ranges, and organizes practical suggestions f

There is no unified formula for pricing used construction machinery, but there are three main threads: condition, hours, and brand value retention. This article combines mainstream domestic models and export market conditions to break down the pricing logic for used excavators, loaders, and bulldozers, providing reference price ranges, inspection points, and negotiation room, and explains how original parts, inspection reports, and logistics costs affect the final transaction price.

When buying used excavators, bulldozers, or loaders, an inspection report is an unavoidable step. This article breaks down the inspection item checklist, report data interpretation, and on-site inspection actions, providing judgment criteria for core items such as hydraulic systems, engines, undercarriages, and electronic controls. It also includes tips for identifying common report falsification methods and special requirements for inspecting export equipment, helping buyers make more
