Introduction of Used 2023 SEM 656F Wheel Loader

This is a pre-owned SEM 656F 5.5-ton heavy-duty wheel loader manufactured in 2023. As the core model of SEM’s F-series under Caterpillar, it inherits Caterpillar’s proven manufacturing standards and is built for high-intensity working scenarios, widely applicable to sand & gravel loading, mining hauling and infrastructure earthmoving. Its low-hour, near-new condition delivers exceptional cost performance.

Overall Appearance

It retains SEM’s signature robust design with original factory yellow-and-black paintwork, free of collision deformation or sheet metal repairs. The wide-articulated box frame, paired with a 3350mm long wheelbase in centered layout, ensures even force distribution and outstanding stability under heavy loads. The original standard bucket is fitted with wear-resistant teeth, with even and minimal wear across the bucket body. All four heavy-duty off-road tires feature deep treads with no damage or uneven wear, delivering strong traction. The wide-opening engine hood, side guards and boarding handrails are fully intact, with neat body lines and excellent exterior condition.

Engine

It is powered by a Weichai WP10H diesel engine meeting China National IV emission standards, with a rated power of 162kW. Adopting 4-valve technology and a reinforced cylinder block, it achieves full combustion and strong torque output. Equipped with multi-mode power switches and an intelligent electromagnetic fan, it balances power performance and fuel economy. The engine has no disassembly or overhaul history, running smoothly at idle without abnormal noise, with clean oil circuits free of leakage and responsive throttle performance.

Transmission & Axles

The drivetrain is equipped with a TR200 fixed-shaft powershift transmission, supporting 4 forward and 4 reverse gears with smooth, jolt-free shifting. It delivers strong traction in first gear and high travel efficiency in high-speed ranges. The split-type torque converter and transmission design ensures convenient and reliable daily maintenance. Both front and rear axles are SEM-manufactured heavy-duty drive axles with large-module spiral bevel gears, featuring excellent load capacity and impact resistance. The axle housings are free of deformation and oil seepage, and the rear axle oscillation structure easily handles unpaved and complex job site conditions.

Operability

The F-series cab offers 20% more interior space with a multi-angle adjustable suspension seat for comfortable operation. The single-lever pilot control is light and precise, and the dual-pump confluence hydraulic system achieves a total cycle time of only 9.3 seconds for fast and efficient work cycles. The full LCD dashboard displays clear information, and the integrated fault self-diagnosis function facilitates daily maintenance.

Overall Condition

With reasonable genuine working hours, the machine has been regularly serviced strictly per official specifications. Its hydraulic and electrical systems operate stably without hidden faults or leakage, with fully verified performance — ready for immediate operation upon delivery. Backed by Caterpillar’s technical system, SEM equipment features high reliability, easy spare parts access and strong value retention, making it a cost-effective premium choice for heavy-duty construction operations.
