The machine adopts crawler movement form, which is flexible in movement and convenient in positioning. In addition, all electrical and hydraulic pressures are centralized controlled, which is easy to operate and reduces the labor intensity of workers.
． The crawler walking system adopts a rigid suspension overall trolley structure, and the upper working mechanism adopts a three-fulcrum structure, which can move into position quickly, safely, stably, and have high construction efficiency. Good quality.
． Except for the four outriggers and the traveling mechanism, which are hydraulically driven, the rest are mechanically driven, making them reliable and easy to maintain.
． Equipped with a variety of working devices, it has a wide range of applications.
． The speed of the winding motor is adjusted by resistance to meet the lifting speed requirements of grouting with different hole diameters. The pile erection is stable, has little impact on the structure of the whole machine, and extends the working time of the whole machine
Crawler pile driver installation operating procedures
The operator of the crawler pile driver must be familiar with the structure, performance, and performance of the machine. Only after passing the examination and obtaining the certificate of operating essentials and safety precautions can you operate alone.
,
The operator must concentrate when operating. Do not talk, laugh, fight or make trouble with unrelated persons. Smoking and eating food are not allowed during operation.
,
Strictly abide by the relevant maintenance regulations of the pile driver and carefully perform maintenance at all levels to ensure that the pile driver is always in good condition. And pay attention to reasonable use and correct operation.
Before working with a crawler pile driver, the following preparations should be made
Learn from the construction personnel about the construction conditions and tasks, as well as the problems found during the construction and matters that the class should pay attention to.
. Adjust the position of the pile driver's transmission gear according to the vibration force required by the construction personnel.
Check whether the insulation of cables and wires is good. Check whether the controller contacts are in good condition and whether the limits are correct.
Check whether the voltage of the power supply meets the requirements.
Lubricate and maintain each part according to daily maintenance items.
Safety precautions for the crawler pile driver at work
When working, there must be a dedicated person to direct it. Commanders and operators should check each other's signals before working. Work closely together.
At the beginning, use an electric bell or other means to send out a signal to notify people around you to leave.
The planes of the drilling rig and the pile cap, the pile cap and the pipe string (or pile) should be leveled, the connecting bolts should be tightened, and regular inspections should be made to see if they are loose.
The starting of the vehicle should be accelerated from low speed gear to high speed gear by gear.
When the drilling rig is working, you should pay close attention to the current and voltage indications on the control panel. If abnormal noise or other abnormal conditions are found, stop the machine immediately for inspection.
Frequently check the bearing temperature and whether the bearing cover screws are loose, and strictly check whether the eccentric iron block connecting screws are loose to prevent accidents.
When sinking, no one is allowed to stand around the pipe string (or pile).
