Easing the maintenance of cranes at the port of Le Havre, France

The port of Le Havre is one of the largest ports in France, handling an annual container volume of more than 2 million TEU while operating under the ‘Grand Port Maritime du Havre’ port authority. The Generale de Manutention Portuaire (GMP), also known as the General of Port Handling, started their operations in Europe in 1976 at the terminal in order to handle an increased volume of containers and vessels. Scanclimber assisted in accessing the port’s cranes for maintenance work by providing a SC300K Hoist.

History

In the early 16th Century, the Port of Le Havre was just little more than a fishing village. A harbor, called the Havre-de-Grace at the time, was being constructed there in 1517. While time passed through the 16th and 17th centuries, the harbor expanded and developed to an extent that it could handle twice the traffic. The traffic kept on increasing by the start of the 19th century due to its expansion to the east. The port of Le Havre played an important role during various wars and battles throughout the years until World War II, when it was nearly destroyed. The port was re-built after the war and it has been expanding since and has been playing a significant role in the country’s trade and economy.

Challenges

One challenge at the port of La Havre was to access the harbor cranes while finding an efficient solution in respect to its installation, maintenance, quick availability of spare parts and to the suitability to the structure of the site. Some major challenges at the site were:

  • Finding measurements for the basic construction of the cranes
  • Replacing the existing hoist
  • Installing a hoist without causing any major structural changes to the site’s basic construction

The purpose of this project was to replace an old hoist with a new one. A major challenge was to have the measurements of the landing and clearance dimensions on the site. This was challenging since the site was old and there were no layout drawings or other dimensional information available. Re-measurements had to be made, which was another test as they had to be carried out while the crane was in operation and the area where the old hoist was installed was contaminated with hydraulic oil. Additionally, it was emphasized to install the Scanclimber hoist without incorporating any major modifications to the crane itself. Scanclimber technicians from Poland addressed these challenges very skillfully. The measuring results enabled Scanclimber to design a customized hoist. The landing and cover panel were adapted in a way that nearly no additional changes on the existing basic construction had to be made. They replaced the old hoist with a new basic industrial hoist which started operating in June 2009.

  • Technical Data Lift Car and Lifting Mechanism
Description of THE SC300K  main components 
  • SC300K Lift
    SC300K Lift
    The lift is a functional complex and consists of the following main components:
     - ground station
     - lift car
     - lifting mechanism
     - mast and landings
  • SC300K Lift Ground Station
    SC300K Lift Ground Station
    The ground station (1) forms a closed car-like structure with a door on one side for access into the lift car. The ground station frame and wall structures are galvanizing steel.
    The door (3) structure is a two-leafed door opening in the middle towards the landing. The door is equipped with a locking device (4), which allows the door opening only when the car is at the ground station. The door is opened manually. The door and the locking device are controlled with limit switches. At the ground station there also is a push button box for calling the lift car.
  • SC300K Mast Section
    SC300K Mast Section
    The cross profile of the mast sections forms a rectangle, hot galvanized, welded structure with square guide pipes in the corners. The interval of the guide pipes is 650 mm.
  • SC300K Landings
    SC300K Landings
    The landing doors (1) are two-leafed doors opening in the middle towards the landing. The door is equipped with a locking device (2), which allows the door opening only when the lift car is by the landing doors.
    The landing door is opened manually. The landing doors and the locking device are controlled with limit switches. By the landing doors, there also is a push button box for calling the car to the landing.
    Below the landing door threshold, there is a door opening wide and 750 mm high kick plate (3).
  • SC300K Lift Car
    SC300K Lift Car
    The lift car forms a closed car-like structure with a door on one side for access into the lift car. The lift car frame structures are hot galvanized steel and the wall structures are painted steel panels. The car door (1) structure is a two-leafed door opening inwards in the middle.
    The door is equipped with a locking device (2), which allows the door opening only when the car is at the ground station or by the landing door.
    Below the landing door threshold there is a door opening wide and 750 mm high kick plate (3). On the car roof there is a 400 x 600 mm sized roof gate (4), through which access to the car roof is allowed. On the roof, there are 1100 mm high safety railings (5) with an intermediate bar and a 150 mm high kick plate (6).
  • SC300K Drive
    SC300K Drive
    The lift’s lifting mechanism consists of one bevel gear, an electric motor and an electromagnetic brake. The motor brake has a hand lever, which in case of an emergency can be used for opening the motor brake to lower the lift car to the ground station or the next landing for safe exit from the car. The lifting mechanism is placed on the car roof.
Description of SC300K  main components 
  • SC300K Lift Shaft
    SC300K Lift Shaft
    The lift's ground station and the frame built under the mast are installed on a steel/ construction foundation. The shaft/ well under the lift is about 1500 mm deep.
    At the ground station, on the frame under the mast there are 2 safety buffers (2), which limit the lift car’s downward movement. The safety buffers prevent in all cases, the descent of the lift car onto the well bottom and leave a necessary space under the car.
  • SC300K Mast
    SC300K Mast
    The mast consists of mast sections with a length of 1508 mm. The mast sections are joined to each other with four M20 – 10.9 bolts and Nyloc nuts. The mast is fastened from the bottom to the ground station's frame structure and to the steel/ construction foundation under the lift. In addition to that, the mast is fastened to the wall structures. The anchor interval of the mast is about 3 m.
  • SC300K Safety Brake
    SC300K Safety Brake
    The safety brake (1) is placed on the car roof.
  • CS300K Safety Brake UC-3.0A
    CS300K Safety Brake UC-3.0A
    During emergency situations the safety brake stops the lift’s downward movement if the lift’s speed becomes faster than the release speed of the safety brake which is 0.9 m/s.
  • SC300K Door opening/Locking System
    SC300K Door opening/Locking System
    The door is equipped with a locking device, which allows the door opening only when the car is at the ground station or by the landing door. The door is opened manually. The door and the locking device are controlled with limit switches.
  • SC300K Load Control
    SC300K Load Control
    The lift is equipped with a load control device, which prevents starting of the lift if the lift is overloaded. The load control device consists of two sensors connected to an electronic control card.
