In daily operation, try to avoid turning the steering wheel to the end, because this will cause severe vibration of the steering mechanism, accelerate component damage. 3) Treatment measures for failure of tires wear: a) For pneumatic tires, tire pressure should be adjusted appropriately to avoid forklift operations in the case of underinflated or excessive; b) From the cost and effect, good quality material can be used in the front tires, and rear tires can use more general material. c) Test and maintain tires regularly, and actively replace with new tires; d) At fault statistics, there are several cases that the left front wheel with brake failure, so you can consider appropriate adjustments in load distribution ratio on both side of front-end of forklift , making tire wear and braking force evenly. 4) For other faults, an effective approach is to strengthen the daily forklift maintenance and standardize the management, to nip it in the bud and prevent security incidents due to the

Materials and methods 1.1 Materials The project selected compound silicate 325 cement, the chemical composition of the X-ray fluorescence see table 1 Table1 : The chemical composition of cement/% SiO2 Al2O3 CaO Fe2O3 TiO2 K2O MgO Na2O S2O3 24.6 7.3 56.9 3.6 0.5 0.6 3.2 0.4 2.6 1.2 Test methods (1)Concrete strength test: reference GBJ 107-1987 concrete strength inspection and assessment; (2)Test hole test: standard molded concrete specimens, to the required age of the specimen with a sharp hammer to knock into 3 ~ 5 mm of small particles, small particles will cutinto 60 mL jars and add alcohol abort hydration. hole before removing the specimen measured particle drying oven at 105 C to remove a sample of alcohol and water can evaporate, after drying specimens at Poremaster 5 meter high pressure measuring holes completed on the mercury experiments
Then can form ，The pore volume of the fractal dimension; P as the material porosity.
Figure 3 describes the hole volume fractal dimension is a material characterized by a description of the pore structure, and can under certain conditions, a comprehensive reflection of the merits of the pore structure of materials, so it is with the strength of the material should also have a certain relationship.
