Typically the base which is bolted into a large concrete pad provides the necessary support for a tower crane. The base is connected to a tower or a mast and stabilizes the crane that is affixed to the inside of the building's structure. Usually, this attachment point is to an elevator shaft or to a concrete lift.
Generally, the mast is a triangulated lattice structure measuring 0.9m2 or 10 feet square. The slewing unit is attached to the very top of the mast. The slewing unit is made of a motor and a gear which enable the crane to rotate.
Tower cranes are able to have a maximum unsupported height of eighty meters or two hundred sixty five feet. The tower crane's maximum lifting capacity is sixteen thousand six hundred forty two kg or thirty nine thousand six hundred ninety pounds with counter weights of 20 tons. Moreover, two limit switches are utilized in order to make certain that the operator does not overload the crane. There is also another safety feature called a load moment switch to ensure that the operator does not exceed the ton meter load rating. Last of all, the maximum reach of a tower crane is two hundred thirty feet or 70 meters.
There is definitely a science involved with erecting a tower crane, specially because of their extreme heights. First, the stationary structure has to be brought to the construction location by using a large tractor-trailer rig setup. Then, a mobile crane is utilized in order to assemble the machinery portion of the crane and the jib. These sections are then connected to the mast. The mobile crane next adds counterweights. Crawler cranes and forklifts may be a few of the other industrial machinery that is typically used to erect a crane.
When the building is erected, mast extensions are added to the crane. This is how the crane's height is able to match the building's height. The crane crew utilizes what is called a climbing frame or a top climber which fits between the slewing unit and the top of the mast. A weight is hung on the jib by the work crew in order to balance the counterweight. Once complete, the slewing unit can detach from the top of the mast. In the top climber, hydraulic rams are used to adjust the slewing unit up an extra 6.1m or twenty feet. After that, the crane operator utilizes the crane to insert and bolt into position one more mast section piece.
Operating a Standard Counterbalance Forklift
1 Before operating the machine, carry out a pre-shift check. Occupational Safety and Health Administration guidelines do state that pre-shift checklists have to be performed each day or every shift. Each and every different machine and its attachments has its own checklist listing lights, emergency brakes, brakes, steering, controls, horn and safety features.
2 When starting up the machine and check the controls, it is important to make certain that the seatbelt is fastened and the seat has been adjusted for your maximum comfort. Look beneath the machine after you move it for any indications of leaks. The operation of each kind of forklift is different.
3 Don't forget differences in the basics of forklift operation as opposed to a standard vehicle. The rear end swing of the forklift occurs due to the fact that the truck steers with its rear wheels. Disregarding this detail is a main reasons for injuries and accidents to employees. The almost 90-degree turn from the front wheels should be performed with great caution. These top-heavy equipment have a high center of gravity even without a load. When lifting or transporting a load this top-heaviness is exacerbated.
4 When traveling, keep the forks close to the floor and use caution when approaching loads. Make certain that the forks line up with the pallet. Lift the load only as high as is required, tilting it back to help stabilize the equipment. Only drive backwards if the load is very big that it obstructs the vision of the operator.
5 Before loading and unloading, check the wheels on trailers/trucks. When lifting a load, it is not advised to travel on slopes. The machinery could tip over on an incline. When driving on an incline is unavoidable, always drive up the incline and back down. The load must be kept on the uphill side of the truck.
6 The forklift operator must always be in firm control all the time. Tipping over is the primary cause of operator injuries. The operator should never try to jump out of the truck in the event of a tip-over. The safest way is to lean away from the direction of fall while gripping the steering wheel and bracing your feet.
