5-ton Chinese wheel loader: how to choose load, bucket and configuration

What “5 tons” actually means

A loader spec sheet has three commonly confused figures: rated load, tipping load, and operating weight. The rated load defines the class. For wheeled loaders with a bucket, ISO 14397-1 calculates rated load as 50% of the full-turn static tipping load (or the hydraulic lift capacity if smaller); Caterpillar uses the same 50% rule.

When comparing offers, always request the full-turn tipping load and the machine operating mass with the quoted bucket. Two machines both labeled “5 t” but with very different operating masses will not perform the same. For reference, this site lists the SEM 655D as 16,800 kg; the XCMG XC958 as 18,700–19,600 kg, with a rated load of 5,500 kg.

For comparison with a familiar model: Caterpillar lists the 950 GC with an operating mass of 18,849 kg, buckets of 2.9–4.4 m³, and a full-turn tipping load per ISO 14397-1 of 11,006 kg; using the same 50 % rule, this corresponds to about a 5.5 t rated load.

Choose the bucket by material and truck

A 3 m³ standard bucket is not suitable for every material. The weight of a full bucket depends on the material’s loose density and the fill factor. Calculation is simple: bucket volume × loose density × fill factor. The result should be close to the rated load, not routinely exceed it.

Densities: soil, sand, gravel, crushed stone and clay from Caterpillar; bituminous coal from Komatsu. Actual values vary with moisture content and particle size. According to Caterpillar, the fill factor is 85–100% for loose aggregates depending on size, and 75–90% for average blasted rock.

Therefore, with gravel or sand at 1,800–2,000 kg/m³, a bucket of about 2.6–2.9 m³ keeps each pass near 5 t; for lighter materials such as coal you may choose a larger bucket: a 4.5 m³ bucket with bituminous coal weighs about 4.0–4.3 t. The SEM 655D offers buckets from 2.7 to 4.5 m³.

For truck loading, Caterpillar recommends 3 to 5 passes to fill an articulated truck, and Komatsu recommends 3 to 6 in mining. For example, if the truck carries 20 t per trip and each pass loads about 5 t, that’s 4 passes—within the recommended range. Also confirm the discharge height clears the truck sideboards.

Engine, transmission and axles

In the 2026 catalog, YUYAN 956G engine options are Weichai WD615G.220 China II, 162 kW, or WP10HG230E670 Euro V, 170 kW. On other models shown on this site, the SEM 655D uses Weichai WD10G and the XCMG XC958 uses Cummins QSB6.7. Request the exact engine model and emissions information quoted, and verify spare parts, local service and compatibility with the destination country’s emissions requirements; import requirements should be confirmed with the local importer or competent authority.

If the machine will operate at high altitude, consider that diesel engine power falls as air density decreases. As a reference, a Cummins diesel generator manual gives a reduction of about 3.5% per 305 m (1,000 ft); exact values depend on the engine, so request the altitude power curve from the manufacturer.

On transmission, the 2026 956G catalog shows a single-phase four-element hydraulic torque converter and a planetary power-shift gearbox, 4 forward 4 reverse; the service brake is four-wheel air-over-oil caliper disc. Also confirm the brands and models of the gearbox and axles and include them in the quotation.

Tires: L2, L3, L4 and L5

Tire codes indicate tread type: “L” denotes loader and dozer tires, and the number indicates tread depth rating. According to manufacturers such as Yokohama OHT, Michelin, Titan and Bridgestone:

23.5-25 is the usual size in this class, and all 5 t models on this site use it (the XC958 in the radial version is 23.5R25). For rock quarries, ask for L5 or reinforced-protection tires; for earth and sand work, an L3 is usually sufficient.

Attachments and special versions

A 5 t loader can work with a standard bucket, rock bucket, light-materials bucket, pallet or log forks, and grapples; if you will change attachments often, request a quick coupler.

With forks, the rated load is calculated differently: according to Caterpillar, SAE J1197 gives 50% of the tipping load, while EN 474-3 can reach 80% on firm, level ground. Ask which standard the spec sheet uses.

For sugarcane there is a dedicated machine: the YUYAN YM6700 cane loader, with 5,300 mm maximum discharge height and 1,200 kg maximum grab capacity, designed to load, stack and transfer cane.

How a 5 t wheel loader is shipped

A loader of this class will not fit in a standard container. The YUYAN 956G measures 8,250 × 2,880 × 3,570 mm (length × width × height) and its bucket is 2,950 mm wide, while a 40' High Cube container door is 2,340 × 2,597 mm (width × height) according to Hapag‑Lloyd. For that reason these machines normally ship by ro-ro, on flat rack, or as breakbulk depending on the loading port and route. Ask the supplier for shipping dimensions and the loading plan.

New or used: request a quote and reference prices

ImportantReference FOB prices are shown for new machines of other brands and for used machines; these are not final quotations. Machines are matched to your request; prices correspond to specific configurations or individual machines and vary with loading port and date. YUYAN 956G is manufactured by YUYAN; request price by configuration. Written quotation is the valid offer.

A used machine costs less up front, but its value depends on the unit: operating hours and the condition of the transmission, axles, articulation and tires. When inspecting a used loader, focus on:

• Play in the center articulation and in the boom and bucket pin joints.
• Forward and reverse shifts are smooth, no slipping, and the torque converter oil temperature is stable.
• Brakes and steering are normal, with no leaks in cylinders or axles.
• Wear on the tires and the bucket cutting edge.
• Check the frame and boom for cracks or repair welds.
