Basic Building Construction Equipment and Machines

Building construction equipments vary from the heavy, large equipment to the mobile, lighter equipment.

Hydraulic excavators, cranes, and concrete mixers are among the basic, hardworking equipments that any building construction company cannot function with.

Hydraulic Excavators

Hydraulic Excavators (also known as diggers or earth movers) are extremely large equipments utilized for multiple operations. They are utilized in applications such as construction of large structures and roads as well as in the mining industry. As one of the first equipment to be applied for readying the construction place, excavators level the land by burrowing and cutting ground. Hydraulic excavators are very functional for certain confined work sites which are less receptive to traditional construction equipment.

The excavator is made up of four basic parts--hydraulic cylinders, arm, bucket, and boom--all involved in loading and excavating. Interestingly, their movement is similar to that of a human arm. The boom acts similar to the upper part of an arm, together with shoulder and elbow. The excavator's arm's movement is likened to a human arm beginning at the elbow to the wrist. And, the bucket is likened to a cupped hand.

Hydraulic excavators consists of loaders, tippers and crawlers (bulldozers). A crawler is a very robust tractor fitted with a dozer blade. Most excavators feature crawlers since they're more functional for operations on mud-covered, rough terrains as compared to wheeled ones.

Cranes

Cranes are equipped with pulleys and levers to haul up and lower sizeable weights. Basically, a crane has a telescopic boom or steel truss that hoists its portable base. Both the levers or pulleys lift the boom, and the boom typically has a hook hanging on it. There are several kinds of cranes including loader cranes and tower cranes. Loader cranes feature hydraulic power booms attached onto trailers. Booms load up materials onto the trailer and may be collapsed after use. Certain types of loader cranes feature telescopic boom for easy operation. Tower cranes are usually the tallest of all cranes. However, they do not feature portable base and parts need to be assembled. These cranes are largely applied to build tall structures and skyscrapers. Primarily exploited for the cutting down of workload, cranes can also perform lots of jobs including moving, digging and creating.

Concrete mixers or processors

Concrete mixers or processors are powered equipment used for mixing cement, water, sand, and gravel to create concrete. A concrete mixer is made up of a rotating drum, a motor, and a trough. The elements applied to create concrete whirls around thus mixing everything consistently.

Concrete processors come in various sizes from the extremely large industrial mixing truck to the smaller, handy concrete mixer. A small concrete mixer is ample for smaller amounts of concrete, up to 2 cubic yards. It's normally run by electricity and features a wheeled base for easier transfer. Its drum can be tilted at an angle so that concrete can be easily dispensed onto the spot that needs to be cemented. A large industrial concrete mixer truck on the other hand, is applied for mixing as well as carrying big amounts of concrete for use on a construction place. These mixers are computer encoded for constant, accurate mix.

Technology indeed creates modern construction equipment to function efficiently, dependably and quickly.
