What Are The Key Specifications Of Hyster H40-70A Forklift?
The Hyster H40-70A forklift series offers load capacities of 4,000–7,000 kg, lift heights up to 7 meters, and IC engine or electric power options. Key specs include 2.5–3.5L diesel/LPG engines, 80V/48V electric systems, and synchronized transmission. Stability features like load-sensing hydraulics and triple-sealed mast designs ensure durability in warehouses, ports, and construction sites. Pro Tip: Opt for electric models in indoor settings to reduce emissions.

What load capacities and lift heights define the H40-70A series?
The Hyster H40-70A handles loads from 4,000 kg (H40) to 7,000 kg (H70) with lift heights of 3–7 meters. Higher models feature dual-stage masts for precision in stacking, while lower lifts prioritize speed. A 7,000 kg H70A can elevate 4.2 meters at 45% load center—ideal for shipping containers. Pro Tip: Always verify load center adjustments to prevent tip-overs with asymmetric loads.
Beyond raw capacity, the H40-70A’s hydraulic responsiveness ensures smooth load handling even at maximum reach. For instance, a 5,000 kg H50A achieves 5-meter lifts in 16 seconds. The dual-path braking system (mechanical and regenerative) enhances safety. But what happens if you exceed the load center? Instability risks spike, stressing axle bearings. Transitioning between tasks? Sync mast tilt (6° forward, 12° backward) with travel speed using the Hyster Stability Manager (HSM) module.
IC vs. Electric Power: Which is better for the H40-70A?
IC engines (diesel/LPG) suit outdoor rough terrain, while 80V electric models excel indoors. Diesel variants deliver 75 HP with 2.5L engines, whereas electrics rely on 750 Ah batteries for 8-hour shifts. Example: A port-based H60A diesel forklift moves 6-ton containers at 22 km/h, but electric models reduce noise by 50%.
While IC engines offer raw power, electric models benefit from zero emissions and lower long-term costs. The 80V electric system supports fast charging (1.5 hours via opportunity chargers) and regenerative braking. However, diesel/LPG remains unbeaten for 12+ hour shifts in remote areas. Pro Tip: Hybrid models (e.g., H50A Hybrid) bridge gaps, cutting fuel use by 30% without sacrificing torque.

How do mast configurations affect performance?
The H40-70A uses duplex/triplex masts with 2–3 stages, balancing lift speed and precision. Duplex masts (H40-H50) lift faster (0.45 m/s) but max out at 5 meters. Triplex masts (H60-H70) prioritize height (7m) at 0.3 m/s. Example: A triplex-equipped H70A reduces pallet retrieval time by 25% in high-rack warehouses.
Mast choice impacts visibility and maneuverability. Triplex designs add 15% more weight, affecting battery runtime. Moreover, mast tilt angles and side-shift options (up to 150mm) enable precise alignment in narrow aisles. Warning: Avoid over-tilting with heavy loads—exceeding 8° forward tilt can shift the center of gravity catastrophically.
What transmission options are available?
The H40-70A offers hydrostatic and synchromesh transmissions. Hydrostatic provides infinite speed control (0–22 km/h) via hydraulic pumps, ideal for smooth acceleration. Synchromesh uses gear-driven mechanics for higher torque (e.g., 420 Nm in H70A). Pro Tip: Hydrostatic reduces driver fatigue in stop-and-go logistics hubs.
Hydrostatic transmissions excel in precision tasks but consume 10% more fuel under heavy loads. Synchromesh, though noisier, suits long hauls on flat terrain. For example, a hydrostatic H50A in a cold storage warehouse maintains consistent speeds despite slippery floors. Why? Fluid viscosity adjustments in hydrostatic pumps prevent jerky movements. Always match transmission type to load frequency and terrain gradients.
| Type | Speed Control | Efficiency |
|---|---|---|
| Hydrostatic | Infinite | 85% |
| Synchromesh | Fixed gears | 78% |
What safety features are critical?
Load Moment Indicators (LMI) and anti-roll tech are vital. The H40-70A’s LMI alerts operators if loads exceed 90% stability limits, while gyroscopic sensors auto-engage brakes during 8°+ tilts. Example: In a construction site, H60A’s LMI prevented tip-overs when uneven ground shifted a 5-ton load.
Additional safeguards include LED headlights for low-light operations and reinforced overhead guards (tested to withstand 1.5x rated loads). But how reliable are these systems? The H70A’s triple-redundant hydraulic valves ensure failsafe lowering even during pump failures. Pro Tip: Pair Hyster’s Safe Access system with motion alarms to reduce pedestrian collisions by 40%.

FAQs
Yes, but ensure BMS compatibility—Redway’s 80V packs include CANbus integration for Hyster’s charge ports, avoiding voltage mismatch errors.
How often should IC engines be serviced?
Every 250 hours: replace air filters and inspect hydraulic lines. Electric models require battery terminal cleaning every 500 hours to prevent corrosion.
What’s the turning radius of H40-H70 models?
2.5–3.1 meters, depending on mast configuration. Triplex masts add 0.2m—plan aisle widths accordingly.
