5-Ton Diesel Counterbalance Forklift | Xinchai 498BPG Turbocharged 4-Cylinder Engine

Meta Description 

The HH50Z 5-ton diesel counterbalance forklift carries 5,000 kg at a 600 mm load centre, weighs 8,550 kg, travels at 28 km/h fully loaded, lifts at 400 mm/s under full load, and has a 3,370 mm minimum turning radius. Available with two engine configurations — ISUZU 6BG1 (82 kW, 411 N·m at 1,600 rpm) or Xichai CA6110 (85 kW, 385 N·m at 2,000 rpm). This page breaks down what the numbers mean and how to choose.

How to Read This Specification Sheet

The HH50Z specification table has two data columns. The model designation is the same in both — what differs is the engine:

• Left column: ISUZU 6BG1 — 82 kW rated output, 411 N·m torque at 1,600 rpm, 6,494 cc displacement

• Right column: Xichai CA6110 — 85 kW rated output, 385 N·m torque at 2,000 rpm, 5,560 cc displacement

Every other value in the specification sheet is identical across both configurations — chassis, mast, dimensions, performance figures, and tyres.

That means the HH50Z procurement decision comes down to a single question: which engine matches your operating conditions?

The sections below cover the shared chassis parameters first, then break down the engine differences.

Chassis Specifications: Identical Across Both Configurations

Lifting Capacity and Fork Equipment

Load centre 600 mm: The 5,000 kg rated capacity is specified at a 600 mm load centre. If the actual centre of gravity of your loads exceeds 600 mm from the fork face — for example, with long or irregularly shaped goods — confirm the effective rated capacity for your specific load geometry with the supplier.

Free lift height 190 mm: The forks can rise 190 mm before the mast extends. This matters when operating inside truck bodies or under low-clearance obstacles: the forks lift off the ground by 190 mm without raising the mast overall height.

Fork outside spread 300–1,830 mm: The same machine handles pallets from narrow to wide without attachment changes.

Overall Dimensions

Operating weight 8,550 kg / rated capacity 5,000 kg = weight-to-load ratio of 1.71:1 — calculated directly from the specification table. This ratio reflects the counterbalance mass relative to the rated load; the specific stability performance is documented in the machine's certification testing.

Min. right-angle aisle width 3,755 mm: This is the minimum clear aisle width required for a right-angle transfer with forks — the hard lower limit when evaluating whether the HH50Z fits your existing racking layout without modification.

Mast lowered height 2,520 mm: The machine's overall height in the lowest mast position. Any doorway, fire shutter, or internal passage with a clear height below 2,520 mm cannot be traversed.

Performance

Full-load travel speed 28 km/h: The speed difference between unloaded (30 km/h) and fully loaded (28 km/h) is 2 km/h — a narrow gap that minimises cycle time variation between laden and unladen runs.

Full-load lift speed 400 mm/s: At the standard 3,000 mm lift height, raising a full load from ground to maximum height takes 7.5 seconds (3,000 ÷ 400 = 7.5 s). This is a direct calculation from the specification values — useful for estimating loading cycle throughput.

Max. gradeability 20%: Rated at full load. If your site has ramps, compare the ramp gradient against this figure. Surface material and ramp length also affect real-world performance; confirm with the engineering team for site-specific assessment.

Undercarriage and Tyres

Front and rear tyres are the same specification (8.25-15-14PR): All four tyres are interchangeable. A single spare tyre covers all four positions — no need to stock two separate tyre sizes.

Frame ground clearance at full load: 160 mm: The lowest point of the chassis is 160 mm above ground when fully loaded. Floor irregularities — expansion joints, raised floor patches, ramp transitions — should be checked against this clearance.

Transmission and Hydraulics

Hydraulic transmission, 2-speed forward and reverse: Direction changes do not require a mechanical clutch, reducing operator input during high-frequency forward-reverse cycles.

Operating pressure 18 MPa: The rated hydraulic system pressure governing lift and tilt actuation.

Engine Parameters: Where the Two Configurations Differ

This is the only part of the specification sheet that differs between the two options — and the only decision to make at the time of order.

Side-by-Side Comparison

Reading the Engineering Differences

Power output: Xichai CA6110 is rated 3 kW higher (85 kW vs. 82 kW), both at the same 2,000 rpm rated speed. The difference is small in absolute terms.

Torque peak and the rpm at which it occurs — this is the most operationally significant difference:

• ISUZU 6BG1 reaches its peak torque of 411 N·m at 1,600 rpm

• Xichai CA6110 reaches its peak torque of 385 N·m at 2,000 rpm

The ISUZU delivers its higher torque figure at a lower engine speed. In practical forklift operation, the conditions that demand maximum torque — heavily loaded starts from standstill, low-speed ramp ascents, initial mast extension under full load — are precisely the conditions where engine speed is lowest. An engine that peaks torque at 1,600 rpm enters its maximum-effort zone earlier in the rpm range than one that peaks at 2,000 rpm.

Displacement: The ISUZU 6BG1 displaces 6,494 cc against the Xichai CA6110's 5,560 cc — a difference of 934 cc (approximately 17%). The larger displacement is consistent with the torque characteristics described above.

Bore × Stroke: ISUZU 105×125 mm (longer stroke relative to bore); Xichai 101.6×114.3 mm (shorter stroke). A longer stroke increases the effective lever arm on the crankshaft, which contributes to higher torque at lower rpm — consistent with the torque figures in the table.

Which Engine for Which Operating Conditions

The following is derived from the specification data only — not a brand recommendation:

ISUZU 6BG1 characteristics match these conditions:

• High frequency of fully loaded starts from standstill (steel yards, port logistics, heavy casting or fabrication shops)

• Sites with significant ramp gradients requiring sustained low-speed torque

• Applications where the engine spends most of its time in the low-to-mid rpm range under load

Xichai CA6110 characteristics match these conditions:

• Applications where slightly higher rated power (85 kW vs. 82 kW) is the priority

• Duty cycles with more continuous mid-to-high-speed running and fewer heavy static starts

• Locations where Xichai service infrastructure is more accessible than ISUZU — verify this directly with local service stations; the specification sheet contains no service network data

Recommendation: Describe your actual operating conditions to the sales team — how often does the machine start from standstill under full load, is there a ramp on site, and which engine brand's service network is stronger in your area. The engine difference is an engineering choice, not a cost one; making the right match at order stage avoids a mismatch you will notice every working day for the next several years.

FAQ

A: Approximately 18 km/h on flat ground when fully loaded; up to 22 km/h unloaded. Sufficient for short-distance transfers between factory areas and warehouse bays.

Q3: What is the fuel consumption?

A: Average combined consumption is 4.5–6 litres per hour, depending on load weight, travel distance and gradient. At a diesel price of 7.5 RMB/L, hourly fuel cost is approximately 34–45 RMB.

Q4: What is the standard fork length? Can it be extended?

A: Standard fork length is 1200 mm. Custom lengths of 1500 mm or 1800 mm are available — please confirm mast compatibility with our sales team in advance.

Q5: What is the warranty period?
