What Are Forklift Parts And Functions?

Forklift parts consist of structural and mechanical components that enable lifting, moving, and load stabilization. Key elements include the mast, carriage, forks, counterweight, and hydraulic systems. The mast raises/lowers loads via interconnected rails and cylinders, while the counterweight balances front-heavy cargo. Power sources (electric batteries or internal combustion engines) drive traction and hydraulics. Safety systems like brakes, lights, and overhead guards ensure operational stability.

What is the role of the mast and hydraulics?

The mast uses telescoping rails and hydraulic cylinders to vertically position loads. Three-stage masts achieve higher lift heights (6–7 meters), while dual-stage designs prioritize visibility. Hydraulic pumps generate 150–300 bar pressure, transmitting force through hoses to cylinder pistons. Pro Tip: Lubricate mast chains monthly—dry operation accelerates wear. For example, a 3,000 kg forklift’s mast might use 30mm-diameter cylinders to handle heavy pallets safely.

How do the carriage and forks function?

Mounted to the mast, the carriage holds forks (1–2 meters long) via adjustable hooks or side shifters. Load capacity depends on fork thickness (20–40mm) and spacing. Hydraulic tilt cylinders enable ±3–5° angle adjustments for secure stacking. Pro Tip: Replace worn fork heels promptly—thinning below 90% thickness risks sudden fractures. Did you know? Fork tip sensors in modern models halt movement if loads shift dangerously.

Why is the counterweight essential?

The rear-mounted counterweight (500–3,000 kg) offsets front load torque, preventing tip-overs. Electric forklifts use lead-acid batteries as dual-purpose counterweights. Pro Tip: Never remove/modify counterweights—even 10% reduction shifts the center of gravity dangerously. For instance, a 1.5-ton forklift lifting 2 tons requires a 2-ton counterweight to maintain stability.

What powers forklifts: electric vs. ICE systems?

Electric forklifts use 48V–80V batteries driving traction motors (10–20 kW) and hydraulic pumps. Internal combustion (IC) models run on diesel/LPG engines (40–100 HP) paired with torque converters. Pro Tip: Electric systems last 1,200–1,500 cycles—deep discharges below 20% halve lifespan. For high-duty cycles, ICE’s 8-hour runtime outperforms batteries.

How do control systems operate?

Control pedals, levers, and joysticks manage acceleration, braking, and mast functions. Regenerative braking in electric models recovers 15–20% energy. Proportional hydraulic valves enable precise speed adjustments. Pro Tip: Calibrate control responses annually—drifting pedals cause jerky movements. For example, Toyota’s SAS system auto-adjusts mast tilt speed based on load weight.
