We would have been still constructing the Panama Canal but for the modern gigantic construction equipments. These Herculean machines made life easy for us by their enormous strengths and capacities for long drawn heavy duties under all torturous conditions.

To think that these engineering marvels work for reclaiming lands from bays, striking piles into the hard sea beds or drilling tunnels deep below the sea beds (Trans European Tunnel connecting England to France), is mind boggling. The list can go endless but for the scope of this article which is limited.

Equipments to Suit All Needs
Construction equipments may be classified as per needs and further by capacities.

1. Excavating and Earth moving: These gigantic machines are hydraulically operated to safeguard from shock failures. These are the first machines to be employed for preparing the construction sites. Land leveling by digging and cutting terrains are done by excavators of appropriate capacities which run into 1000s of HP. Basic earth movers include dozers, tippers and loaders.

2. Concrete processors: Batch or continuous concrete mixers are computer programmed for consistent precise mix. These are stationed permanently near the site or in the factory depending on convenience. Small batch mixers of less than one quintal capacities are portable. The concrete is transported from far off plants in transit mixers of minimum capacity 6 cubic meters by volume. Concrete is poured to the spot using concrete pumps.

3. Bar bending machines: Small high torque generating bar bending machines are handy in bending and forming construction steel bars. These are available in various specifications.

4. Rollers and compactors: Rollers are employed to compact the ground after dozers have leveled it. Some rollers are also equipped with vibrating compactors eliminating the need for separate compacting. For small areas like indoors vibrating plate compactors, which generate up to 1000kgf maybe used.
These are just about the equipments fundamentally required for construction of homes and offices.

Road Construction
For road construction, depending on whether the road is being asphalted or concretized, the equipments change. Asphalt mixers and asphalt pavers take-up the job of road laying to perfection. Concrete road pavers, although work on similar principle, can’t finish the road-laying as concrete needs setting time. There is a need for faster laying technique. Road surface finishing is by a technique called VDF, which stands for vacuum dewatered flooring. Smoother finishes are given by power trowels and anti skid finishes by brooms, mechanized or manual.

Equipments necessary for starting a business in the production of labels


The labels cover a large range of products for which they are destined, and this determines the existence of several types of label creation according to the type of printing used.

The labels cover a large range of products for which they are destined, and this determines the existence of several types of label creation according to the type of printing used.





From the point of view of the printing type used, the labels are of two types: self-adhesive labels which, when packing the products , are taken from the roll, where is used printing on the flexographic machine and the non-self-adhesive labels where the offset printing equipments are used.





For creating the labels using the flexographic printing, first of all, you must acquire a technological line of flexographic plates fabrication , the most indicated being a computer to plate system which transposes the files processed by pre-press directly on the photopolymer plate.





The flexographic printing machine is also necessary, printing the labels with a number of at least 6 groups of colour, and with the optimal maximum printing format chosen in such a manner that, according to the estimations made initially, it ensures a maximum productivity. The flexographic printing machine must have attached upon elimination all the components which allow the achievement of all the necessary finishing: UV varnishing, die-cutting, metallic foil stamping.





For the labels achieved with sheetfed printing, first of all it is necessary to include in the investment plan the sheetfed printing press with at least 6 groups of color and with the maximum print format dimensioned according to the estimates resulted from the market study made before the investment begins.





As for any other sheetfed printing , a guillotine is also necessary, with the maximum opening in accordance with the format of the printing machine, the range of formats which can be cut at this type of equipment must be as large as possible, to be able to reach minimum formats which are as little as possible. It is very important that guillotine be programmable as regards the formats of label which it can cut, because there is increased productivity.





If in the last group, the printing machine cannot ensure the UV varnishing, it is very important to have an UV varnishing equipment at least separately. We can either choose special equipment for this, or an adaptation formed from a classic sheetfed printing machine which lacks the humidification and an UV drying equipment which is placed at the machine elimination.





Also regarding the labels achieved with a sheetfed printing, a metallic foil stamping equipment which can be automatic, semiautomatic or manual according to the dimensions chosen for the business, will be also necessary . For the processing of labels which don’t have a rectangular form, a tunnel puncher whose maximum dimension of processing must be chosen according to the target market that we refer to.
