Generally the base that is bolted into a huge concrete pad provides the essential support for a tower crane. The base is connected to a mast or a tower and stabilizes the crane which is attached to the inside of the building's structure. Often, this attachment point is to an elevator shaft or to a concrete lift.
The mast of the crane is normally a triangulated lattice structure that measures 10 feet square or 0.9m2. Attached to the very top of the mast is the slewing unit. The slewing unit consists of a gear and a motor which allows the crane to rotate.
Tower cranes may have a max unsupported height of eighty meters or two hundred sixty five feet, while the tower crane's maximum lifting capacity is 16,642 kg or thirty nine thousand six hundred ninety lbs. with counter weights of 20 tons. Furthermore, two limit switches are used to be able to make sure that the operator does not overload the crane. There is also another safety feature called a load moment switch to make certain that the driver does not surpass the ton meter load rating. Finally, the maximum reach of a tower crane is 230 feet or 70 meters.
Because of their extreme heights, there is a science involved to erecting a crane. The stationary structure would at first need to be transported to the construction site by using a large tractor-trailer rig setup. Then, a mobile crane is used in order to assemble the equipment portion of the crane and the jib. These parts are then attached to the mast. Then, the mobile crane adds counterweights. Crawler cranes and forklifts may be a few of the other industrial equipment that is usually used to erect a crane.
When the building is erected, mast extensions are added to the crane. This is how the crane's height can match the building's height. The crane crew uses 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 utilized to adjust the slewing unit up an additional twenty feet or 6.1m. Next, the crane operator uses the crane to insert and bolt into place one more mast section piece.
Operating a Regular Counterbalance Forklift
1 Prior to using the equipment, perform a pre-shift inspection. OSHA guidelines do state that pre-shift checklists need to be performed each day or each shift. Each and every different machine along with its attachments has its own checklist listing steering, brakes, lights, emergency brakes, controls, horn and safety features.
2 Start up the machinery and check controls. Primarily ensure your seatbelt is fixed firmly and the seat is firmly in place and adjusted for your comfort. Look underneath the machinery after you move it for any indications of leaks. The operation of every type of forklift is different.
3 Don't forget differences in the basics of forklift operation as opposed to a regular motor vehicle. The rear end swing of the forklift occurs because of the fact that the truck steers utilizing its rear wheels. Disregarding this information is a major cause of accidents and injuries to employees. The almost ninety-degree turn from the front wheels should be made with utmost care. These top-heavy machinery have a high center of gravity even without a load. When lifting or transporting a load this top-heaviness is exacerbated.
4 Keep forks near the floor when traveling. Utilize care when approaching loads. Be sure the forks line up properly with the pallet. Lift the load only as high as is necessary, tilting it back to help stabilize the machine. Drive backwards only if the load is so big that it interferes with the vision of the driver.
5 Check the wheels on trailers/trucks prior to unloading and loading. Do not travel on slopes, especially when lifting a load. The machine is prone to tip-overs on an incline. When driving on a slope is necessary, always drive up the incline and back down. The load should be kept on the uphill side of the truck.
6 The forklift driver must always be in firm control all the time. Tipping over is the main cause of operator injuries. The driver must never try to jump out of the truck in case 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.
