Safe operation of a side lift crane is critical as it involves lifting, moving and placing heavy loads, presenting significant safety risks including equipment tipping, falling cargo, collisions and casualties.
Le fonctionnement sûr d’une grue à levage latéral est essentiel car il implique le levage, le déplacement et le placement de charges lourdes, présentant des risques de sécurité importants, notamment le basculement de l’équipement, la chute de marchandises, les collisions et les accidents.
In order to ensure the safety of side crane operations, prevent accidents, and ensure the safety of life and property, there are some safe operating procedures when operating side cranes.
1. Qualification and authorization:/Qualification et autorisation :
1) Qualified Personnel Only: The operator must be fully trained, assessed and hold a valid operating certificate specifically for this specific model of sidelift.
2) Familiarity with the Equipment: The operator must be fully familiar with the controls, functions, limitations, warning devices and operating manual of the side crane being operated.
3) Authorized operation: Unauthorized personnel are strictly prohibited from operating the side crane.
2. Check before operation:/Vérifiez avant l’opération :
1) Daily Inspection: A thorough inspection (Walk-Around Check) must be carried out before each operation, including but not limited to:
Structure: Check whether the boom, legs, turntable and connecting pins have cracks, deformation, excessive wear or damage.
Hydraulic system: Check whether the oil pipes, joints and cylinders are leaking or damaged.
Wire rope/chain: Check for broken wires, wear, deformation, rust, kinks or damage (check according to scrap standards).
Hook: Check for cracks, deformation, wear (especially the throat), whether it can rotate flexibly, and whether the safety buckle is effective.
Lifting equipment (rigging, slings, shackles, etc.): Check their rated load, clear markings, wear, cutting, deformation, chemical corrosion, etc. It is strictly forbidden to use damaged or defective lifting equipment!
Safety devices: whether the limiters (hook height limiter, amplitude limiter, rotation limiter, etc.), overload protection device, anemometer, sound and light alarm are working properly.
Tires/outriggers: Check whether the air pressure is normal and the wear condition; whether the outrigger pads are complete and in good condition.
Oil: Check whether the hydraulic oil, engine oil, fuel and other fluid levels are normal.
2) Functional test: Under no-load condition, test whether all actions (lifting, lowering, boom adjustment, rotation, telescopic arm, etc.) are smooth and whether the braking is effective.
3) Records: All inspection results and any problems found should be recorded, and no operations should be carried out until the problems are resolved.
3. Work environment assessment:/Évaluation de l’environnement de travail :
site:
The ground must be firm, flat and have sufficient bearing capacity to support the side crane and its maximum load. Pads should be laid if necessary.
Clear the work area of any obstacles, debris, and wires (pay special attention to high-voltage wires! Keep a safe distance).
Identify underground facilities (such as pipelines and cables) and avoid working over them or take protective measures.
Space: Ensure there is adequate room for operation, including boom swing range, load lifting and movement paths.
Weather: Pay close attention to severe weather such as wind speed, rain, snow, fog, haze, and lightning. Comply with the maximum allowable wind speed specified by the manufacturer (usually operations must be stopped if the wind speed exceeds the specified value). Avoid operations during thunderstorms.
Personnel: Define and clearly mark the danger zone. Keep all non-essential personnel away from the work area. Set up roadblocks or arrange guards if necessary.
4. Load handling:/Manutention de la charge :
Know the weight: Never overload! The weight of the load, including the weight of the sling, must be known accurately. Use a certified weighing device or a reliable calculation method.
Understanding the load chart: The operator must fully understand and strictly follow the load rating chart for the side crane’s current configuration (boom length, angle, outrigger extension). The load chart is usually posted in a prominent location in the cab.
Center of gravity and stability:
Understand the center of gravity of the object being hoisted and ensure that the lifting point is selected correctly to stabilize the load.
Use suitable lifting equipment (straps, chains, lifting beams, etc.) to ensure that the load is balanced and secure.
The center of gravity of side lifting is offset, so special attention should be paid to stability during operation to avoid sudden starts and stops or rapid rotation of the boom sideways (especially when it is fully extended).
Test lifting: Lift the load slightly off the ground (a few centimeters), check the balance, stability, braking effect, and whether the lifting equipment is firm and reliable. Continue lifting after confirming that there are no abnormalities.
Smooth operation: All actions (lifting, lowering, luffing, rotation) should be smooth and slow, avoiding sudden starts, stops or sharp turns.
Load Path: Ensure that the load does not strike any object, equipment or personnel during movement. Keep the load as low as possible (above a safe height).
Passing over persons is prohibited: Lifting loads over persons is strictly prohibited.mini graders for sale
It is prohibited to pull or drag the load at an angle: the load must be lifted and lowered vertically. It is prohibited to use a hook to drag or pull the load at an angle.
5. Precautions during operation:/Précautions pendant le fonctionnement :
Stay focused: The operator must focus on the operation at all times and not be distracted (such as using a mobile phone, chatting with others)
Good vision/signal communication:
Ensure the operator has a clear view of the load and path of movement. If vision is obstructed, a qualified and dedicated signalman must be present.
Operators and signalmen must use uniform, clear, and standard hand signals or reliable communication equipment (such as walkie-talkies) and ensure that both parties understand the meaning of the signals.
The signalman should stand in a position where the operator can see him clearly and be in a safe area.
Outriggers: All outriggers must be fully extended and firmly supported on the pads before operation. It is prohibited to lift loads without fully extended or firmly supported outriggers. Outriggers must be retracted during driving.
Swing Area: Pay attention to the swing range of the boom and load and make sure no one is in this area.
Wind influence: When wind speed increases, the load will swing like a sail, increasing the risk of capsizing. Monitor wind speed closely and stop the operation if necessary to lower the load to the ground.second hand graders for sale
No passengers are allowed: It is strictly forbidden to carry passengers on hooks, slings, and hanging baskets (unless they are special personnel hanging baskets that are designed to comply with safety regulations).
It is prohibited to use the hook for pulling: The hook is designed for vertical lifting and must not be used for horizontal pulling.
Off-machine operation: When the operator leaves the cab, the load must be lowered to the ground, the engine must be turned off, and the key must be removed.
6. Closing and maintenance:/ Fermeture et entretien :
Safe parking: Retract the boom to a safe position (usually placed on a bracket), raise the hook to a safe height, retract the outriggers (if applicable), park on a flat and solid ground, and apply the parking brake.
Equipment cleaning: Clean the dirt and oil on the equipment.
Report Problems: Report any problems found during operation or hidden dangers discovered during inspection to your supervisor or maintenance department immediately.
Regular maintenance: Regular maintenance should be carried out in strict accordance with the manufacturer’s requirements and performed by qualified technicians.
7. Emergency procedures:/Procédures d’urgence :
Familiarity with emergency measures: Operators must understand and be familiar with the procedures for handling emergency situations, such as equipment failure, load loss, sudden weather changes, personal injuries, etc.
Emergency Stop: Know how to use the emergency stop button quickly and effectively.
Evacuation: Know how to evacuate safely in the event of a serious incident, such as a tip-over.
8. Management and supervision:/Gestion et supervision :
Establish safety regulations: The company must establish detailed side crane safety operating procedures and work permit system.
Supervision and implementation: Managers and safety officers should monitor whether operators comply with safety regulations.
Continuous Training: Regularly provide refresher training and safety awareness education to operators and signalmen.
Safety Culture: Create a “safety first” culture and encourage reporting of hidden dangers and “right to stop operations”.
Summarize:
Safe operation of side crane /cat grader is a systematic project, which requires qualified equipment, qualified personnel, safe working environment, standardized operating procedures and strict management supervision. The operator’s sense of responsibility and strict compliance with regulations are the core of ensuring safety. Never take chances at any time, and safety must be put first.
