کنترل عملیات لاشینگ کانتینرها (Container Lashing Control)

Lashing is a set of actions that are taken to restrain and stabilize containers on a ship or trailer so that they do not move against the force of wind, waves, vibration, acceleration, braking and dynamic movements..

Accurate control of this operation is one of the most sensitive tasks in safety It is sea and port transportation.

۱. Inspection before starting work

Checking the health of lashing bars, screws, hooks and rods

Ensure no rust, cracks or deformation

Compliance of equipment with IMO standards and ship class

۲. Checking the arrangement of containers

Ensuring the correct placement of containers on the shelves

Control of Twist Locks (Correct lock and unlock)

Checking the center of gravity, elevation and dangerous loads (DG Cargo)

۳. Execution of lashing according to the loading plan (Stowage Plan)

Fastening and tension adjustment of rods, turnbuckles and bridgefits

Adhering to the proper angle of restraint (Usually 30 to 60 degrees)

Using standard equipment with capacity (SWL) suitable

۴. Final control after completing the operation

Checking the uniformity of the stiffness of the restraints

Make sure there are no loose or loose points

Record operations in the ship's logbook or PMS system

Reporting to Chief Officer or Cargo Supervisor

۵. Periodic monitoring during the trip

Scheduled visit when the sea state changes.

Retightening lashings in Sea Passage or when entering rough waters.

Accurate lashing, especially in new generation container ships that load up to 10-12 containers high, is one of the key factors of stability, safety and preservation of cargo value. Without proper control, the smallest error can lead to major accidents.:

Container falling into the sea

Damage to the ship's hull or surrounding structures

Creating large insurance losses

Shifting cargo and disturbing the balance of the ship

Danger to crew and equipment on deck

Unloading bulk containers (Bulk Containers Unloading)

evacuation Bulk containers to the process of exiting bulk materials (Powder, granular or granular) It is said from the container without separate packaging. This operation is carried out in ports, silos and logistics centers with the aim of speed, safety and reducing product loss.

Common methods of unloading bulk containers:

Gravity discharge (Gravity Discharge)

Evacuation with mechanical equipment

Pneumatic discharge (Pneumatic Unloading)

Tilt or overturn Container (Container Tilter)

This unloading method is used for bulk items such as grain and animal feed, cement and minerals, powdered chemicals and polymer granules..

In the late 19th century, the washing machine took its first steps as a semi-automatic mechanical device.. These machines were mostly purely mechanical, powered by hand, belt or, later, rudimentary electric motors..

In 1851, American James King invented and patented the first washing machine using a rotating drum.. The drum was partially filled with water. Seven years later, in 1858, another American named Hamilton Smith built and patented the first washing machine with a rotating drum.. Historians claim that these machines were the first modern washing machines. In 1861, the ability to soak clothes Washing machines added.

Clothes were placed in a metal or wooden tub and washed by vanes, oscillating arms, or a simple drum.. The reciprocating or rotating movement caused mechanical agitation in the water and soap; A process that separates dirt from fibers.

In 1874, William Blackstone, an American businessman, built a machine that would remove dirt from clothes and wash them as a birthday present for his wife.. This device consisted of a wooden tub in which there was a flat piece of wood containing six small wooden pegs. Dirty clothes were hung on wooden pegs and spun in hot soapy water.. Not long after, Blackstone began manufacturing and selling this $2.50 device.

This physical principle is the same concept that is known today as Agitation. Draining water and draining was completely manual and to get the water from the clothes from pressure rollers. (Wringer) was used; Two cylinders between which clothes were passed to remove excess water. Although this part was simple, it was dangerous in terms of safety and later led to the design of safer systems.

In 1907 AD, Alva J. Fisher first Electric washing machine invented in the United States. This machine was called the Thor and was sold by the Hurley Machine Company in Chicago. The said machine was accompanied by a drum, and the blades lifted and washed the clothes by rotating the drum..

As Thor revolutionized the laundry business, other companies focused on consumer markets. Among these companies was Maytag, which started with the production of agricultural tools; But gradually he introduced the wooden washing machine in 1907. In 1911 AD, another famous company called Whirlpool started producing a machine with a rotating drum and an electric motor..

From the point of view EngineeringThese machines were an example of replacing human energy with simple mechanical mechanisms. There was no temperature control, automatic timing, or high-powered motors yet, but these designs were groundbreaking Washing machines They modernized and showed how Engineering It can gradually transform daily tasks.

elevator

1874 AD (1252 solar) It is a turning point in the history of the elevator; When the elevator changed from a simple lift to a safe and reliable vertical transportation system, it paved the way for the growth of tall buildings..

1874 AD, the beginning of the era of safe elevators:
Otis company introduced the first safe hydraulic elevators. Use of safety brake system (Safety Brake) It prevented the cabin from falling if the cable broke. This innovation increased public trust in the elevator.

1880s (1258 solar)The birth of the electric elevator:
In 1880, Werner von Siemens built the first all-electric elevator. Eliminating steam and hydraulic power led to an increase in speed, height and productivity, and laid the foundation for the formation of skyscrapers..

Elevator inspection

1920s, standardization and urban growth:
Introduction of DC motors, pulley system and balance weight and development of sliding doors and basic control systems

1930s, progress in safety and mechanics:
Development of speed governor, improvement of brake system and cabin guide
Increased capacity and available height

1950s, the revolution of AC motors:
Replacing AC motors instead of DC, reducing maintenance costs and increasing life span, smoother movement and less energy consumption of elevators.

1970-1980s, electronics and automation:
Introduction of advanced electronic and relay controls, optimization of waiting time and group management of elevators, development of high-speed elevators for tall towers.

1990s, digital control:
Using microprocessors and PLC, error detection, intelligent monitoring and safety, increasing the stopping accuracy and comfort of elevator movement.

21st century, smart and green elevators:
Gearless motors (Gearless) High efficiency, energy recovery system (Regenerative Drive)High-speed elevators (+10 m/s) And
New technologies like MULTI (Movement without cables)

Since 1874, the elevator has evolved from a risky mechanical lift to a smart, safe, and energy-efficient vertical transportation system. The progress of elevators is directly tied to the development of mechanical, electrical, control, and material engineering, and without it, modern architecture would be practically impossible..
