Ensure You Use Real Tower Crane Inspections Experts

By Jayne Rutledge


Cranes can be very hazardous to workers, as well as pedestrians. There is an OHS law that requires employers to make sure that all tower crane inspections are recorded. Forms are to be filled out either weekly or monthly so that key parts are checked. These must be filled out by the operator as well as the supervisor. Keeping a document of these will insure that if there is ever an incident it will show that the equipment is always kept in working order.

Proper maintenance and regular inspections of vital equipment as well and training is very important to any success of a project. Your companies hoisting and rigging operations are utmost important where even a little mistake can mean disaster. Sometimes even death occurs if rules and regulations are not applied.

Companies can send their employees on a course which usually lasts 3 days. The subjects that are offered cover everything that they will need to know. The erection and dismantling, climbing systems, limit switches, bolting requirements, certification procedures to name just a few. Many of these schools offer accommodations for those who do not live in the area.

The fuel as well as the battery and radiator water levels must be checked. The hydraulics plays a major role so always check that the hoses and connections have no leaks and are not bulging. All controls inside the cabin need to be working well. If any are difficult to work, call your superior. Don't forget to check the tyre pressure and the nuts on the wheels.

In 1908 the first cranes where designed for the construction industry. These appealed to shipbuilders who bought them for use in the shipyards and docks. Over 10.000 units were built and the basic design remained until the late 1960s. Some were very difficult to set up, dismantle, and transport as they were later made from steel and iron.

The anti 2 block system will be next and this is an important device that can prevent catastrophic damage. The crane will then need to hold a specific weight for a period of 5 minutes. It will then be moved 25ft forward and back again so as to ascertain that while in motion it is safe. This inspection can take up to a few hours as it needs to be very thorough.

In Europe building sites were often constricted and had to use rail systems to move large towers. This was proving to be very costly and inconvenient. They were later manufactured offering saddle jib with hook heights of 262ft. They were made with self-climbing mechanisms that allowed sections to be inserted so the structure could grow. The long jibs allowed for larger work areas to be covered. These started the practise of anchoring and erecting inside the buildings lift shaft which is now common in industries.

Brakes need to be checked properly as does the hook. If there is any debris on the surface this needs to be cleaned as it can cause the staff to fall and injure themselves. Any dirt that has gotten into parts of the machine will cause excessive wear and tear and possible failure. If one is unsure the machinery is up to standard, call tower crane inspections experts in your area, for that ultimate peace of mind.
