Tipper bodies have revolutionized how construction materials like sand, gravel, cement, rubble, soil etc. are transported. They consist of an open-topped container body which is hinged at the back and can tip its load by hydraulic, electric or pneumatic mechanisms. This allows for easy unloading of content without any manual labor. The earliest documented use of tipper trucks can be traced back to early 1900s but their widespread adoption began during post-World War 2 industrialization and infrastructure development.
Design and Functions
A typical Tipper Body has a steel frame made of sturdy cross members and side panels. The sides and tailgate are provided with sturdy hydraulically operated hinges and pivots to take heavy loads. The loading space is usually 6-10 cubic meters in capacity depending on truck size. The floor is designed with drainage holes to remove any residual material after tipping. Some advanced designs feature adjustable tailgate openings and detachable side panels for flexible unloading.
Tippers operate by using hydraulic rams connected between chassis and body. The operator presses controls to raise or lower the body between 0-90 degree angles. This allows controlled dumping of content in heaps or spreading uniformly based on project needs. Some electric over hydraulic systems provide automatic functions like pre-set dumping angles. Pneumatic systems use compressed air for faster operation.
Applications in Construction
Tipper trucks are indispensable for various on-site material transportation tasks:
- Carrying and depositing sand, aggregate and gravel for road works, dams, buildings construction etc.
- Transportation and dumping of quarried stone, soil, muck and debris from excavation sites.
- Transfer of ready-mix concrete, mortar from batching plants to construction locations.
- Shifting excavated earth orFill material within project premises in bulk.
- Removal and disposal of demolition and construction waste debris.
Advantages over Manual Methods
Use of tipper trucks provides significant benefits over conventional manual methods of material handling:
- Higher productivity - A single tipper can shift much higher loads compared to manual labor gangs, speeding up works.
- Reduced labor costs - Tippers don't require additional labor for loading-unloading, reducing manpower expenses.
- Improved efficiency - Precise controlled tipping ensures minimal spillage and wastage ofcargo.
- Easy handling of heavy loads - Tippers can easily lift and carry loads exceeding 5-10 tons capacity which is difficult manually.
- All-weather operability - Covered bodies protect material during transportation even in inclement weather conditions.
- Reduced health hazards - Manual material handling poses high risk of injuries which is avoided through mechanized tippers.
Vehicle Matching and Maintenance
Proper matching of tipper body to carrying vehicle's load capacity and terrain conditions is important. Bodies heavier than chassis capacity lead to overloading. Similarly, very large tipper bodies hamper maneuverability in congested sites. Periodic maintenance keeps all hydraulic, electrical and mechanical components functional. Proper lubrication and scheduled component replacement extends tipper life. Regular cleaning prevents build-up of residual cargo.
Safety Compliances
As tipper operation involves overhead lifting of heavy loads, certain key safety practices are mandatory:
- Operator requires heavy vehicle license and safety training on controls.
- Flashers, reverse alarms ensure worker visibility near dump zone.
- Restricted access under elevated body during loading-unloading.
- Annual fitness certification checks structural integrity and functioning.
- Overloading and over-reaching container capacities is strictly prohibited.
- Proper signage prevents pedestrian movement near dump areas.
Future Technologies
Advancements in hydraulics, controls and sensors are delivering added advantages in tipper trucks:
- Fully electric/hybrid systems provide cleaner fuel alternatives.
- Touchscreen controls facilitate monitoring of hydraulic functions.
- Real-time load sensors ensure regulated material flows during dumping.
- Collision avoidance systems using proximity radars enhance safety.
- GPS tracking enables live route monitoring and theft prevention.
Tipper bodies are indispensable components empowering efficient material handling for construction. Their unique dump mechanism has streamlined infrastructure works globally through mechanization. Ongoing innovations will deliver even more optimized solutions in future.
