On the conditions of possible, should set the fork hole or suspending ear for moving goods. The gangplank or transition board should have non slip finishing. On the both sides of the gangplank or transition board, should mounted the facility to prevent the truck from going over it’s edge. When the gangplank or transition board is fixed its location, should adopt measures to prevent the reverse joint truck from moving suddenly.

Lighting

When the photometric brightness on the operating field is less than 32LX, the vehicle should equipped auxiliary light.

The suspending of the truck

The sling should be tied to the lifting spot which the factory appointed.

The synchronizing operation of the truck

Conveying bulky or heavy load using two trucks simultaneously is a dangerous operating which requires special care. And this kind of conditions should be taken as special conditions and carried out under the supervision of the operator responsible for operation.

Elevator (lifter)

The elevator (lifter) for transporting the industrial truck can bear the overall weight of truck, load and the drivers. This kind of elevator (lifter) must be appointed, and the drivers should use the appointed elevator (lifter).

Operating on the road vehicle (trailer) and rail vehicle

Before the motor industrial truck drive to the road, the road vehicle should apply the brake and wedging to prevent moving. Exception: the road vehicle equipped with automatic snap lock type parking brake can not use the wedge. The industrial motor truck passing in and out without connect to the tractor, to prevent the semi trailer hold up can use support It is necessary to build up the operating communication and operating order, to prevent the rail vehicle move accidentally when downloading. The road vehicle (trailer) and rail vehicle should endure the overall weight of vehicle, load and the drivers. It is necessary to inspect if the pavement is crushing, having holes or other damage. When the industrial truck is operating at high place or platform, should not use the industrial truck to move other vehicles. Never open the door of the rail truck using industrial truck; expect for equipped with special device and the driver has passed the train to use the device.

Applied to the driver

The safety operating of the industrial truck lies on the control manner of the driver ro a considerable degree. The safety rules applied to the drives are as follows:

general rule;
transporting (lifting and stacking) rule;
operating (driving) rule;
the rule for the driver maintaining the truck. Without regard to the rules maybe conduce:
the serious danger of damaging the driver or other personnel;
Damage the materials.

General rule

Only the personnel who have been trained and get the qualification of operation are permitted to drive the industrial truck. The motor industrial truck could not carry passengers, except for equipped with the facility for the passengers sitting. The driver should pay special attention to the operating circumstance, including the person nearby other staves and fixed or moving substances, and it is necessary to watch out for the passerby at any moment. No matter whether there is load on the lifting part of the truck, it is forbidden anyone passing or standing under the lifting part of the truck. If the people, building, organization or equipment accident happens, it is necessary to report to the relevant officer at once. The driver should not change, add or demolish the truck components without the permission to influence the performance of the truck .It is not allowed to install accessorial frame or handle on the steering wheel ,except the factory has installed it. The driver should use the truck in the using range. When operating high stacking job, convey high and multi piece piled goods using driving type high-lift truck, it is necessary to use the truck with blind goods shelf and canopy guard shelf. Exception: if there is no danger of the load fall down on the driver, the truck without blind goods shelf can be used. When operating high stacking job, convey high and multi-piece piled goods using walking type truck, the blind goods shelf is necessary.

Load carriage (lifting and stacking) rule

Load

The industrial truck or the combination of the industrial truck and attachment only can convey the load not over its rated load weight. The capacity of the industrial truck with attachment maybe less than the one marked on the nameplate. Any measure of enhancing the capacity of the truck is forbidden, for example the adding people or balance weight. In any conditions, especially when using the attachment, it is necessary to pay attention to the operation, location, fixation and transportation of the load. The truck with attachment when unloaded should be treated as with some capacity. Only the rank stabilized or safety load can be conveyed, especially when convey the super long or high load, should pay special care. When convey the load which center of gravity is uncertain, operating the vehicle should special carefully.

The loading and unloading of goods

When loading the goods with forks: A） The space between the forks should fit the width of the conveying load. B） The fork should insert into the inner of the load as deep as possible. But pay attention to not make the fork tip touch the substance except the load. Then the fork should lift to the enough height to move the goods. C） When conveying high and multi-piece piled goods, it is necessary to tilt the mast back ward a little (if can tilt back) to stabilize the load, and should be careful specially. When unloading the goods, it is necessary to descend carefully. If possible, tilt the mast forward a little (or limited)in order to put ready the load and draw out the fork.

Stacking

When stacking, the mast should tilt backward to ensure the stability of the load, approach the goods pile slowly. When the truck approach and face to the goods pile, it is necessary to adjust the mast to the vertical location, and lift the load a little higher than the height of the pile. Then running backward the truck Or if using reach truck, extense the fork and descend it to unload the goods After lifting, start the vehicle, no matter with or without load, it is necessary to operate the brake carefully and placidly. It is necessary to ensure that the stacking is firm. After stacking, draw off the fork, and lower the fork to the operating height. After confirm there is no block on the road, drive away the truck.
