3.0 Installation 2.73

3.0 rope pressure

4.6.6 ends with wire rope wire rope clips are permitted only in the free fall of the hammer. Rope fixture selection and installation shall comply with Appendix D requirements.

4.7.1 Overview Piling equipment directly involved in the process and not for piling and maintenance hoist lifting platform should meet the requirements of 4.7.2.

4.7.2 Safety Requirements The first layer of wire rope winch maximum allowed tension of, should be represented on the winch plate. Hoist shall be equipped with.

--- Working braking system;

--- Parking brake system. When the winch operating device is not operating or power is interrupted, the parking brake system should be able to automatically load and prevent accidental act of reverse mobile.

Note. The braking system may use common components, such as hydraulically driven winch load or drop-down control valve control device may use as a working brake. Each braking system should at least be able to stop the brake rope pull

1.3 times the permissible work load; steady work available drivers brake system To which the load is decelerated to stop. It should be fitted with a winch to pull the pile measurement system that should be able to display the actual strain of the pile pulling the rope, and the display device installed in the driver Easy to see the place. The aforementioned measuring system can be installed force limiters (such as limiting driving torque) method on the hoist instead. Hoist limit device should be fitted. Before lifting arrival terminal limit device should enable the hoist is stopped. For maximum tension is not Greater than 20kN winch, can be mechanical limit device. May be used when appropriate position before it reaches the end position lifting device audible or visual alarm system, instead of the previous limit Means. Winch free fall movement operations by two independent and simultaneously acting controls. The member must be able to automatically control Reset. In order to make impact with the pile piling devices to maintain continuous contact may be one of the following methods.

--- The hoist can be freely retractable rope hanging piling means;

--- Piling means completely disengaged from the suspension rope. When the winch has a free fall include functions, including a variety of functions, shall be free to install the operation control switch delegated functions.

4.1 Stability

4.1.1 Appendix B stability should be verified. It should be considered to determine the stability angle stability and stability moment two parameters. Piling equipment Manufacturer/supplier should indicate piling equipment can be used stably under what conditions in the manual, and should be verified before delivery stability calculation Qualitative.

4.1.2 Machine for stability calculation of the center of gravity and the quality of the parts should be obtained by calculation or weighing.

4.1.3 Each component manufacturer shall provide all necessary parts and the overall stability of the data related to the calculation.

4.2 Ergonomics Piling equipment ergonomic principles should be designed to minimize driver fatigue and psychological stress and other personnel. Necessary Consider providing protection for the driver gloves, shoes and other personal protection devices. The minimum size of the entrance and a comfortable operating area and operating device can And the scope should be consistent GB/T 8420 and JG/T 81-1999 requirements.

4.3 hot surfaces and sharp edges Personnel may be exposed to hot or cold surfaces shall JG/T 83-1999 requirements in

4.8 with shields to prevent or cover plus Protection. Sharp edges should be GB/T 17301 requirements inverted obtuse.

4.4 hydraulic and pneumatic hoses or pipes Hoses and pipes shall comply with the appropriate hydraulic safety standards. Pipes, hoses and fittings must meet the pressure hose should be marked with its rated working pressure. The driver may cause damage to the hose pipe or breakable parts should JG/T 83-1999 in

4.9 requirements, install anti Shield.

4.5 Isolation of the power source

4.5.1 Except as specified in 4.5.3, the application of the cage to isolate all sources of power, and effective heat dissipation. Cage should be Clearly identified and can be locked.

4.5.2 After the power source is turned off, the device should be piling pipe loads may cause harm to the human body removed.

4.5.3 To maintain the state, to protect information and internal lighting circuits, in a non-hazardous state can keep the power supply. But such The case should ensure driver safety measures.

4.6 Pulley, drum and rope

4.6.1 pulley and reel diameter shall meet the following requirements.

4.6.2 Security laps rope remain on the drum should be at least three times.

4.6.3 reel side to the outer edge of the outermost layer of wire rope distance not less than 2 times the wire rope diameter.

4.6.4 Lateral rope pulley and/or between the roll off angle, for non-rotating or anti-rotating wire rope should not exceed 2.5 °, for which His wire rope should not exceed 4 °.

4.6.5 rope breaking load of not less than the following safety factor (see Table 1) when multiplied by the lifting rope to withstand the maximum static load or Maximum hoist wire rope pull. Table 1 wire rope safety factor Working conditions Safety Factor General lifting or pulling piles

4.8 Transport and mounting device

4.8.1 In order to secure parts removal, handling and transportation equipment, lifting points should be set, hanging ears, rings and eye bolts or other devices Set (see 5.2.4). Piling equipment

4.8.2 can swing the upper part, the mechanical locking device shall be installed or limiter to prevent the transport (such as roads, rail or Maritime) rotate the upper part.

4.9 Driver position In addition to piling equipment is not possible or suitable for installation outside the cab of the case, should be installed to ensure that the cab driver from the noise, dust and not The adverse effects of climate. In the case of falling objects piling equipment operation, shall be designed and installed falling object protective equipment (FOPS). The FOPS should be consistent GB/T 17771-1999 in reference II. Piling equipment in all cases shall be equipped with a protective roof. Protective roof shall comply with GB/T 17771-1999 in reference I. Should consider taking precautions to prevent damage caused by the ejecta. Cab shall meet the following conditions.

--- In case of necessary and feasible, should be equipped with proper ventilation, heating or cooling system;
