Box 192 · Clifton, TX 766343Safe Practices and ProceduresResponsibility"It is the responsibility of the employer to train the employee in the proper selection and usage of tools, chains, etc., and to ensure that they are selected and used in that manner. In many instances, injury results because it is assumed that anybody knows how to use common hand tools. Observations and the record show that this is not the case. A part of every job instruction program should therefore be detailed training in the proper use of hand tools (and of all other special tools and equipment needed to accomplish the job)." - (Source: National Safety Council)"Employers are responsible for the safe condition of tools and equipment used by employees, including tools and equipment which may be furnished by employees." - (Source: OSHA 1910.242A)Replacement PartsUse only PETOL replacement parts - no other parts are of comparable strength, quality and interchangeability.SafetyWhile we pride ourselves on the quality and dependability we build into GEARENCH tools and products, we caution users that it is only prudent to know and follow the simple rules of safety when using our products, or anyone else's.Always follow safe practices and procedures in accordance with the recommendations of OSHA, The National Safety Council (NSC), The Hand Tools Institute (HTI), The National Association of Chain Manufacturers (NACM), The International Association of Drilling Contractors (IADC), Etc. All applicable Governmental rules, regulations or restrictions, now in effect or which may be promulgated, take precedence over the suggestions in this publication. The information in this publication is designed to supplement standard safe practices and procedures, not in lieu of, or replacement thereof.Safe Practices(Source: The National Safety Council)Failure to observe one or more of the following five safe practices accounts for most hand and powered tool accidents:1. ALWAYS WEAR SAFETY GOGGLES TO PROTECT EYES2. SELECT THE RIGHT TOOL FOR THE JOB3. KEEP TOOLS IN GOOD CONDITION4. USE TOOLS CORRECTLY5. KEEP TOOLS IN A SAFE PLACE4Safety Goggles must always be worn by persons in any area where hand and powered tools are being used.Never apply excess leverage to a wrench or tool by means of a "Cheater Bar". Never strike wrenches and tools with hammers or other objects.All tools should be kept clean, inspected on a regular basis, and replaced when they show signs of wear.Be especially careful not to place yourself in a position that could result in bodily injury in the event of a failure. Brace yourself firmly and pull rather than push when wrenching. (If necessary to push, do so with the flat of the hand rather than gripping around the wrench.)Never stand under or near loads being hoisted off the ground.READ SAFE PRACTICES AND PROCEDURES MANUAL, CATALOG INFORMATION AND PRODUCT LABELING PRIOR TO OPERATION.Spinning and drill pipe chain, cathead chain, and the PETOL Connecting Link attachment are designed for the specific purpose for which the name indicates. Chains and attachments that are to be used for any other purpose should be selected in accordance with the recommendations of ASTM, NACM, Rigger's Handbook, and the commercial chain manufacturer's technical manuals.Safety Sources and PublicationsIn the interest of Safety the following sources of Safety information is furnished:The Hand Tools Institute (HTI)25 North BroadwayTarrytown, New York 10591(914) 332-0040The National Safety Council (NSC)1121 Spring Lake DriveItasca, Illinois 60143-3201(630) 285-1121International Safety Council1121 Spring Lake DriveItasca, Illinois 60143-3201(630) 285-11215Responsibility of DistributorsIT IS THE RESPONSIBILITY OF THE PURCHASERS OF GEARENCH PRODUCTS TO CONVEY THE INFORMATION IN THIS PUBLICATION AND ANY OTHER INFORMATION RELATING TO THE INDIVIDUAL PRODUCT, THROUGH THE CHANNELS OF DISTRIBUTION, DOWN TO AND INCLUDING THE INDIVIDUAL USING THE PRODUCTNOTE:In view of the fact that the actual use determines whether safety requirements have been met, the ultimate responsibility to comply rests with the end user.The service life of leaf chains can be altered by a variety of adverse operating conditions. The following information discusses the most important of these conditions for consideration when operating or scheduling replacement of leaf chain systems.Overloading / Shock Loads / Side LoadingAttempting to “inch loads which are beyond the rated capacity of the tool.Striking the tool with a hammer or other object while force is being exerted in an attempt to loosen a “frozen” joint.Side pull can be caused by pulling or pushing on the tong in a direction that is not along a perpendicular plane, unleveled mounting of the tong, inadequate support of the part being broken out, and improper seating of the part being broken out in the ton. Improper seatingwill occur when the diameter of the part is not consistent within the width of the tong jaw.6Environmental ConditionsTongs operate in widely varying environments, from wet outdoor conditions to mildly or highly corrosive industrial atmospheres. They can also be exposed to abrasives such as sand or grit.The possible effects include:Moisture - Corrosion and rust reduce strength by causing pitting and cracking.Temperature - Very cold temperatures reduce strength by embrittlement.Chemical Solutions or Vapors - Corrosive attack of components’ grain structure and/or the mechanical connections between the components (crevice corrosion) may occur.Cracking often is microscopic. Propagation to complete failure can be eventual orsudden.Abrasives - Accelerated wearing and scoring of the articulating members may occur, witha corresponding reduction in strength.These conditions, when coupled with normal wear, can result in environmentally assisted failure. It is impossible to predict life under complex conditions, as the degree of hostility and its effects are dependent on many variables such as temperature, time of exposure, concentration of corrosive atmosphere or medium, degree of abrasive wear, etc. Establishing the degree and frequency of unpredictable dynamic loading is also difficult.7Safety Precautions1. Always wear safety goggles to protect eyes.2. Select the right tool for the job.3. Keep tools in good condition.4. Use tools correctly.5. Keep tools in a safe place.6. Wear protective clothing, gloves and safety shoes as appropriate.7. Use lengths of assembled chain. Do not build lengths from individual components.8. Do not attempt to rework damaged chain by replacing only the components obviously faulty. The entire chain may be compromised and should be discarded.9. Never electroplate assembled leaf chains or components. Plating will result in failure from hydrogen embrittlement.10. Do not weld any chain or component. Welding spatter should never be allowed to come into contact with chain or components.11. Leaf chains are manufactured exclusively from heat-treated steels and therefore must not be annealed. If heating a chain with a cutting torch is absolutely necessary forremoval, the chain should not be reused.12. Inspect chains frequently and regularly for link plate cracking, pin turning, pinprotrusion and corrosion.13. Use only PETOL & TITAN replacement parts to ensure proper strength.8OperationThe Petol SlimGrip Tong may be used in any orientation. Push the tong onto the pipe to latch. No adjustment is needed for various diamters. Position the tong with the pipe as far back on the jaws as possible.The tong may be pulled by hand, hydraulic cylinder, overhead hoist, cable, or any other means provided that the load is monitored to prevent overloading.WARNING: Never use a cheater or any other means to extend the handle length.WARNING: Under no circumstances should the maximum working load be exceeded. Overloading may result in injury or death. Always use a load cell or other calibrated indicating device to monitor the line pull on the tong to avoid an overload.The tong will exert torque in the direction shown. The tong will ratchet when moved in a direction opposite to the line pull. Ratcheting is used when the tong must be pulled more than once to completely makeup or breakout the connection.To remove the tong from the pipe, simply open the tong by pulling on the upper jaw as shown in the diagram above.9SLG10 DimensionsSLG13 Dimensions10SLG15 Dimensions11Parts ListThe following drawings, diagrams, and parts lists describe all parts, which may be needed as replacement items.All tong components are manufactured only by GEARENCH. DO NOT ATTEMPT TO SUBSTITUTE THESE COMPONENTS. The tong will not work properly unless these components are matched to the specific application. Consult our factory as your requirements change. Any non-GEARENCH substitutions of these components void all warranties and subject the user to assumption of liabilities resulting from subsequent use.12Non-Destructive EvaluationThe figure below indicates the critical areas of the lower jaw. A critical area is defined as an area with no indications of a major dimension greater than 1/8” and no weld repairs are permitted. There are no critical areas on the handle and grip that meet these criteria. There are no nom-critical areas on all other components.13Weld RepairsThis procedure is to be followed for minor repairs of indications in heat treated alloy steels. A weld repair shall be considered minor when the depth of the cavity does not exceed 50% of the actual wall thickness or 1 inch, whichever is smaller, or when the extent of the cavity does not exceed approximately 5 square inches. Major weld repairs must be performed by Gearench or an approved repair center using appropriate procedures followed by full heat treatment or by replacing the component.Application:This procedure applies to steel castings, forgings and, wrought with carbon content between 0.15% and 0.31%.Weld preparation:The crack indication is to be removed by carbon arc gouging, grinding, or machining until all indication is removed. Magnetic particle inspection shall be used to verify that the crack indication has been removed.Filler material and process:Repairs made with the FCAW process shall use a filler material of class E120T5-K4 or equivalent with CO2 shielding gas. Repairs made with the SMAW process shall use a filler material of type E-12018-M. All welding is to be performed by a qualified welder.Preheat:Preheat the weld area to 300°F minimum.Interpass temperature:The interpass temperature is to be 600°F maximum. All weld slag to be removed prior to application of additional layers by chipping, grinding or wire brushing.

Post heat immediately after welding to 1010 - 1040°F for 1 hour per inch of thickness, 2 hours minimum at temperature. Water quench after stress relief.Weld blending and inspection:The weld is to be ground flush with the adjacent parent material. The weld is to be inspected by magnetic particle to verify that the weld area is free of all crack indications.14。
爬梯护笼的防滑要求及材质选择
爬梯护笼的防滑要求及材质选择随着建筑业的发展，爬梯护笼在工地施工和维修中起到了至关重要的作用。
然而，由于施工现场的复杂情况和天气的影响，护笼上的防滑要求变得尤为重要。
在本文中，我们将探讨爬梯护笼的防滑要求及材质选择，以确保工作人员的安全。
一、防滑要求1. 摩擦系数爬梯护笼的防滑性能主要依赖于摩擦系数。
摩擦系数是指两个物体表面接触时所产生的阻力。
对于爬梯护笼而言，我们希望其表面有足够高的摩擦系数，以防止工作人员在行走时滑倒。
一般来说，梯子的摩擦系数应该大于0.6才能满足安全要求。
2. 表面纹理除了摩擦系数，爬梯护笼的表面纹理也对防滑性能有着重要影响。
表面纹理越粗糙，摩擦力就越大，防滑效果就越好。
因此，在选择材质时，需要考虑其表面纹理的特性。
二、材质选择1. 钢板钢板是常见的爬梯护笼材料之一。
它具有耐腐蚀、耐磨损的特点，并且容易进行表面处理以提高防滑性能。
钢板的防滑效果较好，可以满足大部分工地的需求。
2. 铝合金铝合金是另一种常用的材料选择。
它具有轻质、耐腐蚀的特点，并且易于加工成型。
铝合金的防滑性能较好，但相比钢板稍逊一些。
在选择铝合金材质时，需要注意其表面处理，以提高防滑效果。
3. 塑胶塑胶材料在一些特殊工地中也得到了广泛应用。
塑胶的防滑性能较好，并且具有一定的减震效果。
此外，塑胶材料还具有绝缘性能，适合在一些需要防电的环境中使用。
然而，在选择塑胶材料时，需要确保其坚固耐用，以满足工作环境的需求。
综上所述，爬梯护笼的防滑要求很高，对材质的选择也非常重要。
在选择材料时，我们应考虑摩擦系数和表面纹理，以确保护笼具有良好的防滑性能。
钢板、铝合金和塑胶都是常见的材料选择，具有各自的优势和适用范围。
在实际工程中，需要根据具体情况选择最合适的材料，以确保工作人员的安全。

小鸟入笼的设计原理
小鸟入笼的设计原理
小鸟入笼的设计原理是利用小鸟的天性和笼子的结构，以达到固定和保护小鸟的目的。
1. 笼子的结构：笼子通常由金属丝网或者竹子等材料制成。
丝网的网眼大小可以根据小鸟的体型来设计，以防止小鸟逃脱或者被外界的天敌攻击。
笼子的底部通常是实心的，以提供足够的支撑力，防止小鸟从底部逃脱。
2. 笼子的尺寸：笼子的尺寸应该能够容纳小鸟自由活动，如飞翔、站立、转身等，同时也不能太大，以防止小鸟因为飞行过长的距离而受伤。
3. 笼子的门：笼子上的门通常是用金属制成的，并且有锁或者其他的安全装置，以确保小鸟不会被人为或者意外地打开门而逃脱。
4. 笼子的垫料：笼子的底部通常铺设一定厚度的垫料，如木屑、报纸等，以吸收小鸟的排泄物，并且易于清理。
5. 笼子的摆放位置：笼子的摆放位置应该远离直接阳光照射，防止小鸟中暑或者热伤，同时也要注意保持通风和干燥的环境。
总体而言，小鸟入笼的设计原理是为了提供一个安全、舒适和适宜的生活环境，以满足小鸟的生存和生活需求。
