Usually, 6 tons of on-board crane drivers are required to undergo professional training. After passing the check, they will be given motor vehicle driving licenses and special working certificates for lifting machinery to be able to drive and operate the truck crane. Unauthorized persons, post-drinking or physical indications should stop the operation of the vehicle. The driver shall, in accordance with the rules of the manufacturer, timely maintain and maintain the lorry crane, and perform regular inspections to ensure that the vehicle is always in a state of absence. It is necessary to operate according to the rules of weight bearing characteristics and working radius to stop overloading. The ground on which the vehicle is parked should be flat and solid, and it should be kept in safe intervals with the ditch and foundation pit. It is necessary to retract the boom, hooks and legs before proceeding. Adhere to medium speed while traveling and prevent emergency braking. When passing through railway crossings and uneven roads, it is necessary to slow down. It is necessary to stop the neutral gear when descending the slope, and there is a need for guardianship when reversing. When the truck is hanging in winter, the road surface should be equipped with anti-skid measures.
6 tons of truck crane in the lifting work, the hook and the pulley to maintain a certain interval, to prevent the winding over the limit to pull off the wire rope or boom back. It is forbidden to carry out repairs and adjustments. Stop irrelevant personnel from entering the cab . Stop the staff from lifting up and down by hanging objects, and stop the hand from touching the wire ropes and pulleys during work. Whether you are hanging or hanging in the air during a strike or rest, there must be sufficient lighting for work at night. In the work, there are conditions such as subsidence of the outriggers and sloping cranes. It is necessary to immediately put down hanging objects and continue to work after adjusting and eliminating unsafe elements. After the work, the arm of the truck crane should be fully retracted, placed properly, and hooked. The brakes of each organization must be firmly braked.
It is necessary to adjust the work of the leg when there is no load, retract the now extended arm, and stop the operation of the valve on the leg. 6 tons truck crane Before lifting, it is necessary to check whether the crane parts are completely intact and comply with the safety rules. After the crane is started, it should be unloaded to check the operation equipment, brakes, hydraulic equipment and safety equipment. The work of the parts is not normal and sensitive. Before work, attention should be paid to obstacles within the crane's swing range. When the site is relatively soft, it is necessary to carry out a trial run to see if the legs of the crane are loose or subside, and it is possible to continue lifting under the condition of admitting normal conditions. When lifting a heavier item, the weight should be lifted from the floor by 10 cm to see if the crane's stability and brakes are sensitive and useful. It is possible to continue lifting under the recognition of normal conditions.
