1.6Relationship between load and stability of truck It is very important for operator to know the truck’s structure and relationship between load and stability. Warning! The structure of the truck The basic structure of the truck is mast (include mast and forks) and body (include tire). The lift truck keeps the balance of weight between the truck body and the load on the forks with the center of the front wheels as a...
Page 27
Warning! Gravity and stability The combined center that is composed of the barycenter and the load center determine the stability of lift trucks. When unloaded, the barycenter does change; when loaded, barycenter is determined by the truck and the load’s center. The barycenter is also determined by the tilting and lifting of the mast.
Transport and Commissioning 2.1Transport 2.1.1Lifting the truck by crane • The Fork Lift Truck is designed for material handling only, inappropriate long-distance transportation. The Fork Lift Truck must be transported by ship, train or lorry, of 5T loading. • Use a lifting sling to hoist the truck. •...

The “Safety Instructions” covers basic safety procedures and warnings of general application to the typical forklift truck. However, safety precautions given on the following pages are also applicable to lift trucks that have special specifications or attachments.
Page 32
6. Prevent exploding Because there will bring exploding gas in the bosom of the battery, prohibit any flame nearby it absolutely. Don’t let any tools close the two terminal of the battery to avoid spark or short circuit. Make sure to operate the truck on concrete firmly enough or bituminous macadam.
Page 33
11. Pay attention to the route of the truck ·Pay attention to the route of the truck, be sure to make a wide sight. 12. Don’t offer rides to others Never allow other person(s) to ride on the forks, pallets or on the truck. 13.
Page 34
The pallet and skid used should be strong enough to endure the load. Never use damaged or deformed ones. 18. Use proper attachment We afford all type of attachment, such as rotating roll clamp, bale clamp, side shifter, and crane jib. You should refit the truck under ours license if you want.
Page 35
23. Don’t stack load too high on forks Don’t stack loads on forks in such a way that the top of loads exceeds the load backrest height. If unavoidable, make the load stable securely. When handling bulky loads that restrict your vision operate the truck in reverse or have a guide.
Page 36
28. Watch for doorways and Slow down at corners Watch for branches, cables, doorways, or overhangs. Use caution when working in congested areas. Slow down and sound horn at cross aisles other locations where vision restricted.When make a turn, be sure the speed of the truck is lower than the 1/3 max.
Page 37
lose balance. Slow down for wet and slippery roads. Stay away from the edge of the road. If the ground is bumpy, it will cause the truck bump and bring much noise. Do not operate the truck when the weather is execrable, such as windy, thunder storm, snow and etc.
