7/18/2019 Safety


32 SEBU8495-03Safety SectionEquipment Lowering with Engine Stopped

A well trained operator that follows the instructionsin the Operation and Maintenance Manual hasthe greatest impact on stability. Operator trainingprovides a per son with the following abilities:observation of working and environmental conditions,feel for the machine, identification of potential

hazards, and operating the machine safely by makingappropriate decisions.

When you wor k on side hills and when you work onslopes, consider the following important points:

Speed of travel – At higher speeds, forces of inertiatend to make the machine less stable.

Roughness of terrain or surface – The machinemay be less stable with uneven terrain.

Direction of travel – Avoid operating the machineacross the slope. When possible, operate the

machine up the slopes and operate the machinedown the slopes. Place the heaviest end of themachine uphill when you are working on an incline.

Mounted equipment – Balance of the machinemay be impeded by the following components:equipment that is mounted on the machine, machineconfigur ation, weights, and counterweights.

Nature of surface – Ground that has been newlyfilled with earth may collapse from the weight of themachine.

Surface material – Rocks and moisture of the

surface material may drastically affect the machine'straction and machine's stability. Rocky surfaces maypromote side slipping of the machine.

Slippage due to excessive loads – This may causedownhill tracks or downhill tires to dig into the ground,which will increase the angle of the machine.

Width of tracks or tires – Narrower tracks or narrower tires further increase the digging into theground which causes the machine to be less stable.

Implements attached to the drawbar – This maydecrease the weight on the uphill tracks. This may

also decrease the weight on the uphill tires. Thedecreased weight will cause the machine to be lessstable.

Height of the working load of the machine –When the working loads are in higher positions, thestability of the machine is reduced.

Operated equipment – Be aware of performancefeatures of the equipment in operation and the effectson machine stability.

Operating techniques – Keep all attachments or pulled loads low to the ground for optimum stability.

Machine systems have limitations on slopes –Slopes can affect the proper function and operationof the various machine systems. These machine

systems are needed for machine control.

Note: Safe operation on steep slopes may requirespecial machine maintenance. Excellent skill of the operator and proper equipment for specificapplications are also required. Consult the Operationand Maintenance Manual sections for the proper fluidlevel requirements and intended machine use.

Information Concerning Whole BodyVibration Level

This section provides vibration data and a method for estimating the vibration level for skid steer loaders.

Note: Vibration levels are influenced by manydifferent parameters. Many items are listed below.

• Operator training, behavior, mode, and stress

• Job site organization, preparation, environment,weather, and material

• Machine type, quality of the seat, quality of thesuspension system, attachments, and condition of the equipment

Precise vibration levels for this machine are not

possible. The expected vibration levels can beestimated with the information in Table 1 in order to calculate the daily vibration exposure. A simpleevaluation of the machine application can be used.

Estimate the vibration levels for the three vibrationdirections. For typical operating conditions, use theaverage vibration levels as the estimated level. Withan experienced operator and smooth terrain, subtractthe Scenario Factors from the average vibration levelin order to obtain the estimated vibration level. For aggressive operations and severe terrain, add theScenario Factors to the average vibration level inorder to obtain the estimated vibration level.

Note: All vibration levels are in meter per secondsquared.

Guards(Operator Protection)

SMCS Code: 7150-MCH; 7325

There are different types of guards that are used to

protect the operator. The machine and the machineapplication determines the type of guard that shouldbe used.

A daily inspection of the guards is required in order tocheck for structures that are bent, cracked or loose.Never operate a machine with a damaged structure.

The operator becomes exposed to a hazardoussituation if the machine is used improperly or if poor operating techniques are used. This situation canoccur even though a machine is equipped with anappropriate protective guard. Follow the establishedoperating procedures that are recommended for your

machine.

Rollover Protective Structure(ROPS), Falling Object ProtectiveStructure (FOPS) or Tip Over Protection Structure (TOPS)

The ROPS/FOPS Structure (if equipped) on your machine is specifically designed, tested andcertified for that machine. Any alteration or anymodification to the ROPS/FOPS Structure couldweaken the structure. This places the operator

into an unprotected environment. Modifications or attachments that cause the machine to exceed theweight that is stamped on the certification plate alsoplace the operator into an unprotected environment.Excessive weight may inhibit the brake performance,the steering performance and the ROPS. Theprotection that is offered by the ROPS/FOPSStructure will be impaired if the ROPS/FOPSStructure has structural damage. Damage to thestructure can be caused by an overturn, a fallingobject, a collision, etc.

Do not mount items (fire extinguishers, first aidkits, work lights, etc) by welding brackets to the

ROPS/FOPS Structure or by drilling holes in theROPS/FOPS Structure. Welding brackets or drillingholes in the ROPS/FOPS Structures can weakenthe structures. Consult your Caterpillar dealer for mounting guidelines.

The Tip Over Protection Structure (TOPS) isanother type of guard that is used on mini hydraulicexcavators. This structure protects the operator inthe event of a tipover. The same guidelines for theinspection, the maintenance and the modification of the ROPS/FOPS Structure are required for the TipOver Protection Structure.

Other Guards (If Equipped)

Protection from flying objects and/or falling objects isrequired for special applications. Logging applicationsand demolition applications are two examples thatrequire special protection.

7/18/2019 Safety



Guards

A front guard needs to be installed when a work toolthat creates flying objects is used. Mesh front guardsthat are approved by Caterpillar or polycarbonatefront guards that are approved by Caterpillar areavailable for machines with a cab or an open canopy.On machines that are equipped with cabs, the

windows should also be closed. Safety glasses arerecommended when flying hazards exist for machineswith cabs and machines with open canopies.

If the work material extends above the cab, topguards and front guards should be used. Typicalexamples of this type of application are listed below:

• Demolition applications

• Rock quarries

• Forestry products

Additional guards may be required for specificapplications or work tools. The Operation andMaintenance Manual for your machine or your work tool will provide specific requirements for theguards. Consult your Caterpillar dealer for additionalinformation.
