According to ASME B30.16, frequency of periodic inspection depends on the severity of usage: Disassembly may be required for Heavy or Severe usage. Keep accumulative written records of periodic inspections to provide a basis for continuing evaluation. Inspect all the items shown in "Frequent Inspection" section of Product Information Manual (47584686001). Also, inspect the following: 1. Fasteners: Check all rivets, split pins, capscrews and nuts. Replace if missing or tighten if loose. 2. All components: Inspect for wear, damage, distortion, deformation and cleanliness. If external evidence...

Inspection Figure 1. Chain Records and Reports Inspection records, listing all points requiring periodic inspection should be maintained for all load bearing equipment. Written reports, based on severity of service, should be made on the condition of critical parts as a method of documenting periodic inspections. These reports should be dated, signed by the person who performed the inspection, and kept on file where they are readily available for review. Load Chain Reports Records should be maintained documenting the condition of load chain removed from service as part of a longrange load...

Inspection Report (a) Maximum test load should neverexceed 125% of rated capacity. This form may be photocopied and used as an inspection record.

This section provides basic troubleshooting information. Specific causes to problems are best identified by thorough inspections performed by personnel instructed in safety, operation and maintenance ofthis equipment. The chart below provides a briefguide to common hoist symptoms, probable causes and remedies.

Never perform maintenance on the hoist while it is supporting a load. Before performing maintenance, tag controls: Only allow personnel trained in service and repair of this hoist to perform maintenance. After performing any maintenance on the hoist, test hoist before returning hoist to service. Turn off and lockout/tag out electrical disconnect switch before performing any maintenance. The lower sheave block or hook assembly must be lying on the floor or a maintenance platform before beginning service. WARNING - DO NOT OPERATE - EQUIPMENT BEING REPAIRED. General Maintenance Instructions It...

Do not heat a part with a flame to free it for removal, unless the part being heated is already worn or damaged beyond repair and no additional damage will occur to other parts. NOTICE In general, the hoist is designed to permit easy disassembly and assembly. The use of heat or excessive force should not be required. 5. Keep the work area clean to prevent dirt and other foreign matter from getting into bearings and other moving parts. All seals and ‘O’ Rings should be discarded once they have been removed. New seals and ‘O’ Rings should be used when assembling the hoist. When grasping a...

Maintenance Cover Removal Electrical side is indicated by Symbol. Brake System (DC Brake) The spring loaded brake is an solenoid operated single disk brake with two friction surfaces. The braking force is applied by springs. The braking torque is generated when no current is applied. The ventilation is solenoid. The brake operates with DC current. In the power free mode, the brake must be able to hold the nominal load without any problems. Figure 2. Brake CAUTION The brake coil voltage must be the same as the operating voltage. NOTICE Replace brake discs if they are distorted or severely...

Brake Test 1. Use a test load that is 100% of hoist capacity. 2. With cover off, hoist load, in low speed mode, approximately 1 ft. (0.3 m). 3. Listen to brakewhile hoisting. 4. When hoisting stops, brake should hold load. Table 4. BrakeAir Gap (DC Brake) Load Chain Before conducting maintenance on the hoist, lower and remove suspended load. Disconnect electrical supply and remove hoist from overhead suspension. • The chain is to be replaced when the measurements exceed those defined in Table 2 'Load Chain'. The chain wheel and chain guide are to be checked for wear at the same time, and,...

Screw connections at the limit stop and shims at lower sheaves are to be checked and, where necessary, tightened to the right torque. For torque values see Table 5, p. 14. Table5. TorqueValues The gear has continuous lubrication The Gear Compartment is filled with grease at the factory. Replacement of thegrease for the life of the hoist is not required. Slip Clutch The slip clutch is set to work at 125% and prevents overloading of the chain hoist. This is in accordance with DIN EN 14492-2. Resulting force arising from adjusting the slip clutch must be absorbed by the suspension parts. The...
