Plant Management Flashcards
Reason For Using construction plant
◌ increases output
◌ reduces costs
◌ handles tasks that can’t be done manually
◌ reduces worker fatigue
◌ maintains production rates and high standards.
Factors to Consider in Plant Selection:
• Company Policy
• Money Availability
• Extent of Use
• Plant Output
• Versatility
Advantages of Buying Construction Plant:
• Always available when needed.
• Lower idle time costs compared to hired plant.
• Costs can be allocated to various contracts as needed.
Advantages of Hiring Construction Plant:
• Can be hired as needed for short periods.
• Hire firms handle repairs and replacements.
• No leftover expensive plant items after project completion.
• Hiring rates may include operator, fuel, and oil.
• Reduces storage requirements.
Factors to Consider When Establishing a Plant Yard
◌ Storage space
◌ Office space
◌ Space for maintenance, repairs and servicing
◌ Fuel storage space
◌ Training centre
◌ Traffic flow
◌ Security
Benefits of a Compacting Machine
• Increased Stability: Compressed dirt is flatter, providing better stability for equipment like forklifts and cranes.
• Higher Load Capacity: Stable, flat surfaces allow lifting devices to safely haul heavier loads.
• Stronger Materials: Compactors increase the density of materials like concrete, making them more durable.
• Reduced Water Seepage: Compressed soil traps water underground, preventing damage and work delays.
Name and explain Types of Rollers
- Self-Propelled Roller: Hand-guided, compact, and fits into smaller spaces.
- Single Drum Vibratory Roller: Driven by an operator, uses a vibrating drum to compress soil.
- Large Dual Vibrating Drum Roller: Features two drums for more efficient soil compression.
- Smooth Wheel Roller: Best for compacting gravel, crushed rocks, and sand; not suitable for wet conditions.
- Multi-Tire Pneumatic Roller: Uses multiple tires to apply even pressure, ideal for thin soil particles.
- Sheepsfoot Roller: Has steel protrusions for compacting fine-grained soils and clay, used in large projects like dams and railroads.
- Grid Roller: Uses a steel grid to break down large rocks and compress soil, typically attached to another vehicle.
Name and explain Types of Concrete Batching Plants
- Mobile Concrete Batching Plant: Portable and can be moved to different locations.
- Stationary Concrete Batching Plant: Fixed in one location, suitable for long-term projects.
- Transit/Dry Mix Concrete Batching Plant: Mixes concrete during transit to the site.
- Wet Mix Concrete Batching Plant: Mixes all ingredients, including water, before transit.
- Concrete Mixer: A standalone mixer for smaller projects or specific mixing needs.
Concrete Pumps
Used to transfer liquid concrete at construction sites
Concrete Pavers
Used for slipform paving of streets bridges parking lots runways curbs gutters and moreThey ensure speed precisionand high-quality performance.
Concrete Transit Mixers
Transport concrete from the batching plant to the siteThey have a spiral blade inside the drum to mix and discharge concrete
Concrete Boom Placers
Use a remote-controlled arm to place concrete accuratelyEssential for high-rise projects due to their range and precision.
Cranes
are ideal for moving heavy loads on various projectsRenting offers easy access to different types of cranes on a daily
Types of Earthmoving Equipment
ExcavatorsSkid Steer Loaders Backhoes Bulldozers Wheel Loaders
Excavators
Versatile machines with a bucket on an arm and a rotating cab
