EUROSTYLE VATAL and EUROSTYLE VFTAL
jib cranes with aluminium hollow profile arms

VERLINDE is now marketing two EUROSTYLE series jib cranes the booms of which are made of EUROSYSTEM ALU aluminium hollow sections. EUROSTYLE VATAL and EUROSTYLE VFTAL are designed for loads of from 63 to 2000 kg, and through radial distances of from 2 to 8 metres depending on the model.EUROSTYLE VATAL wall mounted jib crane.

EUROSYSTEM ALU sets itself apart by the lightness of its aluminium hollow sections with a rolling coefficient enabling, in the first place, effortless travelling trolley positioning and secondly, easy handling of the unit. EUROSYSTEM ALU enables the weight of VATAL and VFTAL jib crane arms to be cut by 50% compared with conventional steel structures. The lightness of the rails provides easy, effortless manipulation by the operator even with heavy and unwieldy loads.

EUROSTYLE VATAL is a wall mounted jib crane able to work through 180°. It is the ideal solution for work stations located near walls and vertical structures. It is an indispensable backup for overhead cranes in any workshop. Workstations thus become more autonomous with consequent increased efficiency.

EUROSTYLE VFTAL is a column mounted jib crane enabling load handling through a defined area of 270°. This type of jib crane is chosen when no appropriate means of vertical support is available near the workstation.

The two jib cranes have many operational advantages due to the use of EUROSYSTEM ALU profiles. The aluminium is anodized outside and inside meaning remarkable resistance to wear. Furthermore, they are compatible with all ITEM standardized accessories and guaranteed weld-free for greater safety. Finally, the noticeable evenness of the track surface ensures noiseless operating.

MEIJE installs VERLINDE EUROBLOC VT hoists for the
renovation of 6 EDF hydroelectric dams on the River Maulde

There are some 2,250 hydroelectric installations of various sizes in Metropolitan France whose power varies from 1,000 watts to several hundred megawatts. 436 of them are operated by EDF. Out of the total installed capacity of 25.4 gigawatts nationwide, EDF produces no less than 20 gigawatts or 13% of the company's total energy production.A smallish watercourse 70 km long whose source is in the commune of Gentioux-Pigerolles (Creuse department) and mouth at Saint-Léonard-de-Noblat (Haut-Vienne department) where it flows into the River Vienne is the River Maulde on which EDF operates six dams with a combined power output of 18 megawatts. Located at Martinex, Fleix, Langleret, Villejoubert and Lartige, the six gravity dams, most of them Ambursen type dams, roughly 16m high, have buttresses spaced at intervals and are of identical design.

Improved efficacy for renovation operations
Each dam is made up of five sections (with the exception of Lartige) on four of which are mounted a bulb unit fitted with an asynchronous generator while the fifth section is used when an emptying operation is necessary.

Each section equipped with a bulb unit is made up of a water intake tower, a penstock with a 90° elbow and a butterfly type slide valve. Until now, the EDF maintenance and servicing teams used a 15-tonne capacity hoist that they moved from one group to another and from dam to dam.

EDF is at present faced with the challenge of heavy renovation works on each of the six dams' sections. Alluding to this operation and on behalf of Meije, José Lima explained that with a single hoist the operation would take too long. "the invitations for tenders put out by EDF therefore involved, on the one hand, the renovation of the existing monorail tracks and supports and, on the other hand, the supply of five identical and easily movable mobile monorail hoists. Our bid with Verlinde hoists won the contract
because it precisely met the specification sheet conditions both in terms of price and of equipment quality.

EDF decided to install a Verlinde EUROBLOC VT standardized 2m/M5 hoist on each section of the dam being renovated, each with a lifting capacity of 15 tonnes and lifting height of 15 m. This hoist enables operations on the heaviest parts of the bulb group located in the section at the base of the dam. The five sections equipped in this way enable simultaneous work on the five groups and keep production downtime to a minimum. After 12 to 16 months' work, when renovation work is completed, the hoists can be easily dismounted using a screw plate system we have designed. They are then set up on the next dam."
