Inspecția înainte de tură a stivuitorului electric: Ce ar trebui să verifice operatorul?
Un stivuitor electric așteaptă lângă punctul de încărcare la începutul unui schimb. Ecranul pornește, iar utilajul a funcționat normal ieri. Poate operatorul să înceapă mutarea paleților?Încă nu. O scurtă inspecție poate dezvălui o roată deteriorată, o scurgere hidraulică sau un sistem de control al siguranței defect înainte ca stivuitorul să intre pe un culoar aglomerat din depozit. Această listă de verificare pentru inspecția stivuitorului electric folosește modelele QSLIFT QES10E și QES15E ca exemple practice. Respectați întotdeauna manualul de utilizare pentru modelul specific, deoarece componentele și procedurile de inspecție pot diferi.
De ce trebuie inspectat un stivuitor electric înainte de fiecare schimb?
Stivuitoarele electrice combină deplasarea asistată electric, ridicarea sarcinilor, frânarea, sistemele de baterii și controalele de siguranță ale operatorului. Un defect în oricare dintre aceste zone poate afecta operatorul, pietonii din apropiere, mărfurile, rafturile și utilajul în sine. O inspecție constantă înainte de fiecare schimb ajută echipa din depozit să:
- – Detectarea timpurie a daunelor vizibile
- – Prevenirea transformării defecțiunilor minore în reparații majore
- – Reducerea timpilor de nefuncționare evitabili
- – Retragerea din serviciu a echipamentelor nesigure
- – Îmbunătățirea comunicării dintre operatori și tehnicieni
- – Menținerea unei evidențe clare a inspecțiilor. Efectuați inspecția înainte ca utilajul să fie utilizat pentru prima dată în schimb.
Verificați-l din nou după o coliziune, după ce un alt operator raportează o problemă sau ori de câte ori comportamentul utilajului se schimbă.
Începeți cu podeaua și zona înconjurătoare
Faceți o ocolire în jurul stivuitorului înainte de a atinge comenzile. Verificați podeaua de sub unitatea de acționare și catarg pentru urme de ulei, apă sau alt lichid inexplicabil. Nu căutați o scurgere hidraulică cu mâna. Lichidul sub presiune poate pătrunde în piele.c
Căutați, de asemenea:
- Folie stretch, benzi de ambalare sau sârmă în apropierea roților
- Obiecte lăsate libere în zona de încărcare
- Deteriorarea încărcătorului, a cablului sau a fișei
- Urme care sugerează contactul cu rafturile sau pereții
- Obiecte care blochează traseul stivuitorului
Dacă nu puteți identifica sursa unei scurgeri, izolați utilajul și solicitați unui tehnician calificat să o inspecteze.
Șase zone de verificat la un stivuitor electric cu pietoni (însoțitor)
Ilustrația următoare prezintă principalele zone exterioare ale unui stivuitor din seria QES.
Zone de inspecție: 1 furci; 2 roți de sarcină; 3 catarg, lanțuri și zona de ridicare hidraulică; 4 șasiu și capace; 5 comenzi pe timonă; 6 baterie și zona de oprire de urgență.
1. Furci
Priviți de-a lungul ambelor furci, de la călcâi până la vârf.
Verificați pentru:
- Fisuri
- Îndoiere sau răsucire
- Înălțime egală a furcilor / Înălțime neuniformă a furcilor
- Damaged fork tips
- Severe wear
- Semne ale unui impact Furcile trebuie să par drepte, paralele și poziționate uniform. Opriți utilizarea stivuitorului dacă o furcă pare mai joasă, mai uzată sau aliniat diferit față de cealaltă.Nu încercați niciodată să îndreptați sau să sudați o furcă deteriorată fără o evaluare tehnică autorizată.
2. Load wheels
Load wheels work close to the floor and can collect packaging material.
Inspect the visible wheels for:
- Cuts, cracks or missing material
- Flat areas
- Uneven wear
- Plastic film, string or wire
- Damage around the wheel mounting
- Restricted movement
A damaged or obstructed wheel can cause vibration, poor tracking and difficulty crossing floor joints.
Remove only loose debris that you can reach safely. Ask a technician to remove material trapped inside the wheel assembly.
3.Mast, chains and hydraulic system
Inspect the mast from outside the guarded area. Keep your hands, head and tools away from the lifting mechanism.
Look for:
- Visible mast distortion
- Damaged or heavily corroded chain sections
- Chains that appear unusually loose or uneven
- Oil around cylinders, hoses or connections
- Foreign material inside the mast channels
- Damaged guards
- Loose or missing visible fasteners
The operator should identify obvious abnormalities, not adjust the chains or dismantle the mast. Qualified technicians must perform chain measurement, adjustment and hydraulic repairs.
4.Chassis and protective covers
Walk around the driving unit and inspect its external condition.
Confirm that:
- Covers and panels remain secure
- No sharp or broken edges are present
- The chassis has no obvious impact damage
- Ventilation openings remain clear
- Protective guards are correctly fitted
- Safety labels remain readable
- The capacity plate is present
A cracked cover does not always make a stacker unsafe. However, it may show that the truck suffered an impact. Report the damage so the service team can decide whether to inspect the components underneath.
5.Tiller and operating controls
The tiller is the operator’s main connection with a pedestrian stacker.
Before switching on the machine, look for:
- A cracked or damaged handle
- Loose switches or buttons
- Damaged control housings
- Exposed wiring
- Missing control symbols
- A tiller arm that does not move normally
After the visual inspection, test the controls in a clear area. Travel, steering, lifting and lowering should respond smoothly and predictably.
Also test the horn, braking and the tiller-head reversing safety function where fitted. Stop if a control sticks, reacts slowly or causes unexpected movement.
6.Battery, charging connection and emergency stop
First, confirm that the charger is disconnected. Then inspect the visible battery and charging components.
Check that:
- The battery has sufficient charge for the planned work
- The plug and cables show no visible damage
- No conductors are exposed
- Connectors sit in their correct positions
- There are no signs of burning or overheating
- The battery remains correctly retained
- The display shows no unresolved battery fault
The red emergency-stop button must remain accessible and undamaged. Test it according to the machine instructions and confirm that it resets correctly.
Do not use a damaged charging plug or cable. Never modify a connector or bypass a battery-protection system.
Close-up inspection points
Close-up examples: A, forks and fork heels; B, load wheel and nearby packaging debris; C, externally visible mast chain and hydraulic area; D, emergency-stop button and charging plug.These images show the boundary between an operator inspection and technical maintenance. The operator can look for visible defects and test normal functions. However, the operator should not remove covers, adjust chains, open electrical systems or attempt unauthorised repairs.
Perform a functional test
Once the visual inspection is complete, switch on the stacker in a clear area. Test it without a load and follow the instructions for the specific model.
A general functional check includes:
1. Check the display for fault warnings.
2. Test forward and reverse travel at low speed.
3. Confirm that steering responds normally.
4. Test the braking response.
5. Raise and lower the forks through a short movement.
6. Check that the lift action feels smooth and controlled.
7. Test the horn.
8. Test the emergency-stop and relevant safety functions.
9. Listen for unusual mechanical or hydraulic noise.
Stop the inspection if the stacker:
– Moves unexpectedly
– Brakes poorly
– Produces grinding, knocking or scraping sounds
– Vibrates more than usual
– Lifts unevenly or with a jerking movement
– Continues moving after the operator releases a control
– Produces a burning smell
– Leaks fluid
– Displays an unresolved safety-related warning
The ability to lift a pallet does not prove that the machine is fit for service.
Check the route and first load
A stacker may pass its machine inspection but still be unsuitable for the planned task.
Before handling the first pallet, ask:
- Is the floor dry, level and free from serious damage?
- Are there ramps, gradients or dock edges on the route?
- Can pedestrians remain separated from the truck?
- Is there enough space at corners and doorways?
- Is the pallet stable and undamaged?
- Is the load centred on the pallet?
- Is the load weight known?
- Is the required lift height suitable for the machine?
- Are overhead pipes, doors or other obstructions present?
- Does the racking show visible damage?
Read the machine’s capacity information rather than estimating capacity from its physical size. Lift height, load centre and equipment configuration can affect the permitted load.
Do these checks apply to electric pallet trucks?
QSLIFT EPT15V and EPT20V electric pallet trucks share several inspection points with pedestrian stackers.
Operators should still inspect the forks, load wheels, chassis, tiller, brakes, battery and safety functions. However, an electric pallet truck does not have a stacker mast or high-lift chain system. Therefore, use a checklist written for the correct equipment category rather than copying the stacker checklist without adaptation.
When should the stacker be taken out of service?
Stop and report the machine when a defect could affect safe operation.
Examples include:
- Cracked or bent forks
- Damaged mast components or lifting chains
- Hydraulic leakage
- Wheels that affect travel or stability
- Weak or inconsistent braking
- Uncontrolled travel, lifting or lowering
- Exposed electrical conductors
- Damaged battery connectors
- A defective emergency-stop or safety control
- Missing protective components
- An unreadable capacity plate
- An unresolved safety-related warning
Follow the site’s isolation procedure so another operator cannot use the stacker. An authorised person should decide when the machine can return to service.

Before handling the first pallet
- The route and operating area are suitable.
- The pallet and load are stable.
- The load weight is known.
- The machine’s rated capacity is suitable.
- The required lift height has been confirmed.
- Pedestrian risks have been considered.
Reporting Defects
Every warehouse should define:
- Who completes the inspection
- Where the result is recorded
- How the operator reports a defect
- Who isolates the machine
- Who contacts the service provider
- Who authorises its return to operation
A paper checklist may be sufficient for a small fleet. A larger operation may prefer a digital system linked to individual trucks. In either case, the process must make defects visible and assign responsibility for the next action.
For model-specific inspection points, consult the operating manual supplied with the machine. When contacting a QSLIFT dealer or service partner, provide the model and serial number so the team can identify the correct documentation and parts.
