• Drive motors are dual 8.1 kW AC motors; pump motor rated at 23.8 kW.
• Battery systems operate at 80V nominal voltage with capacities between 600-700 Ah.

Chassis and Tires

• Tire options include solid rubber (V), superelastic (SE), pneumatic (P), and polyurethane (PE).
• Front tires typically sized 250-15 or 28 x 12.5-15; rear tires 21 x 8-9.
• Wheel configuration consists of two driven front wheels and two rear wheels.
• Track widths and wheelbase are engineered for stability and maneuverability.

Basic Dimensions and Ergonomics

• Mast tilt angles: 6° forward and 10° backward to facilitate efficient loading/unloading.
• Operator compartment features adjustable steering wheel, suspension seat, and optimized pedal layout for ergonomic comfort.
• High visibility overhead guard and wide operator view enhance safety.
• Controls include fingertip forward/reverse lever and multifunction switches for lights and horn.
• Self-diagnostic LCD monitor displays real-time system status, fault codes, and allows performance mode selection.

Hydraulic and Brake Systems

• Advanced hydraulic system with large capacity, low-noise control valves.
• Enclosed wet disc brakes protect against dust and water, requiring minimal maintenance.
• Down-control and down-safety valves ensure controlled lowering and prevent fork drop during hydraulic failure.
• Fully hydrostatic power steering provides smooth, precise control and prevents kick-back.

Safety Features

• Operator Presence Sensing System (OPSS) disables mast tilt, lift, and drive controls when operator is not seated.
• Anti-rollback system ensures safe ramp operation and ramp starts.
• Robust overhead guard exceeds EEC and ANSI safety standards.
• Parking brake uses a ratchet mechanism requiring less operator effort.
• Rear safety lamps include turn signals, tail, and brake lights for enhanced visibility.

Electrical and Control Systems

• High-frequency (8 kHz) ZAPI AC controller enables smooth operation, improved motor efficiency, and fault protection.
• Regenerative braking functions during direction changes, deceleration, and braking.
• Multiple performance modes: High (H), Normal (N), Economic (E), and Turtle mode (limited to 10 km/h).
• DC-DC converter complies with UL and CE standards to prevent electrical faults.

Maintenance and Serviceability

• Battery replacement facilitated by swing-up compartment with gas-spring assisted cover.
• Oil tank port and brake oil level checks are easily accessible.
• ORFS (O-Ring Face Seal) hoses prevent hydraulic oil leaks.
• Consolidated fuse box allows straightforward inspection.
• Enclosed AC motors with no brushes or commutators enhance durability and reduce maintenance.

Mast and Load Handling

• Available mast types include 2-stage limited free lift and 3-stage full free lift.
• Load capacities vary by mast type and load center; detailed tables specify maximum fork heights, free lift, and load capacities.
• Wide range of attachments offered, such as side shift, hinged forks, buckets, clamps, and load extenders.

Optional Equipment

• Beacon lights available in amber, red, and blue; rear work lights.
• Cold storage options for low-temperature environments.
• Various tire options including pneumatic and non-marking types.
• Multi-valve control (MCV) with 4 spools and 4 levers.
• Different fork sizes to accommodate specific application needs.

Summary

The Hyundai 7-Series electric forklifts integrate advanced AC motor technology, ergonomic operator design, and robust hydraulic and safety systems to provide efficient, safe, and comfortable material handling solutions. Their modular mast and attachment options enable customization for diverse operational requirements, while maintenance-friendly features minimize downtime and reduce operating costs.

Additional Dimension Specifications

• Dimensions are presented in length x width x height format, with consistent cross-sectional sizes of 150 x 50 mm.
• Lengths vary widely from 50 mm up to 1,970 mm, indicating multiple size options or product variants.
• The "50B-7" designation corresponds to a series of components with lengths ranging from 1,220 mm to 1,970 mm, maintaining the 150 x 50 mm cross-section.

This data likely represents standardized component or material specifications with fixed cross-sectional dimensions and variable lengths, suitable for construction, manufacturing, or engineering applications.
