B40 Electric Forklift
MYZG 4-Ton Heavy-Duty Lithium Battery Electric Forklift (Model: B40)
High-Capacity 4000kg Heavy-Industrial Lithium-Ion Forklift Engineered for High Breakout Torque, Tough Outdoor Yards, and Multi-Shift Intensive Material Handling.
Executive Overview: Uncompromising 4-Ton Industrial Capacity Meets Clean Energy
The MYZG B40 4-Ton Lithium Battery Electric Forklift is a high-performance industrial workhorse designed by Mingyu Heavy Industry (MYZG) to eliminate the efficiency gap between internal combustion diesel trucks and clean electric forklifts. Purpose-built for heavy-duty material movement, this machine allows enterprises to replace emissions-heavy 4-ton diesel forklifts in stone processing plants, heavy machinery manufacturing, timber yards, paper mills, and port logistics terminals.
Driven by a ultra-high-voltage 154V / 150Ah lithium accumulator battery pack, the B40 delivers an impressive rated load capacity of 4000 kg (8,800 lbs) at a 500 mm load center. Featuring a powerful 13.1kW traction drive motor, a massive 16.5kW hydraulic oil pump motor, a generous ground clearance of 160 mm, and heavy-duty pneumatic tires, the B40 easily negotiates rough terrain and ramps up to a 15% grade while generating zero carbon emissions.

Engineering Breakdown & Key Product Advantages
1. High-Voltage 154V/150Ah Lithium System & Dual Heavy Motors
The MYZG B40 utilizes a high-voltage 154V / 150Ah lithium-ion battery architecture that delivers sustained high-current output under peak payload stresses. Paired with a 13.1kW traction drive motor and a powerful 16.5kW hydraulic oil pump motor, the machine achieves full-load lifting speeds up to 300 mm/s and unladen travel speeds of 13 km/h. Lithium battery technology supports fast opportunity charging, allowing 24/7 multi-shift utilization without battery swaps or acid maintenance.
2. 160mm High Ground Clearance & Heavy All-Terrain Pneumatic Tyres
Built for brutal industrial site environments, the B40 features an exceptional 160 mm minimum ground clearance—one of the highest in its class—along with a sturdy 1980 mm wheelbase. Coupled with heavy-duty pneumatic tires (28x9-15 front, 6.50-10 rear), it easily crosses mud, railway crossings, potholes, and gravel yards without scraping its chassis.
3. Robust 4820kg Chassis Weight & Ergonomic Driver Cabin
With a net machine weight of 4820 kg, the B40 provides a rock-solid center of gravity during 4-ton lifting maneuvers. The sit-down cabin features 980 mm of head space under a reinforced 2165 mm overhead guard frame. The wide-view mast offers tilting angles of 6° forward and 12° backward, allowing operators to safely secure cumbersome 4-ton loads during travel.
4. 260mm - 1100mm Wide Fork Adjustment Range & Braking Reliability
The fork positioner spread ranges from 260 mm to 1100 mm, making the truck highly versatile for non-standard timber pallets, large machinery crates, or stone bundles. Reliable mechanical foot and hand brake systems ensure full braking security, holding 4-ton payloads securely on 15% inclines.
Target Application Environments
The heavy 4000 kg capacity, 160mm ground clearance, and zero exhaust output make the B40 ideal for tough outdoor and indoor heavy industries:
Stone, Concrete & Brick Yards
Moving heavy granite slabs, precast concrete blocks, and masonry pallets over outdoor gravel yards.
Heavy Machinery & Foundries
Handling steel castings, heavy metallic molds, engines, and industrial machinery parts indoors and outdoors.
Paper Mills & Lumber Depots
Transporting jumbo paper rolls, timber bundles, and plywood crates safely across multi-shift routines.
Frequently Asked Questions (FAQ)
Q: What is the minimum turning radius and right-angle aisle width for the B40?
A: The B40 features a minimum turning radius of 2650 mm and requires a right-angle channel width of 4405 mm for handling standard 1100x1100mm pallets.
Q: How does the 160mm ground clearance help in outdoor operations?
A: The high 160mm clearance prevents the undercarriage and motor housings from hitting obstacles, railway tracks, or uneven surfaces in outdoor stone yards and construction sites.
Q: What are the benefits of the 154V high-voltage lithium system?
A: Higher voltage reduces current draw and heat buildup during heavy 4-ton lifting, leading to higher motor efficiency, longer battery life, and superior torque output on steep inclines.
