2.3.2 Optional Inspection Hooks The Inspection Hook is designed to facilitate the inspection of the internal surfaces of the hook yoke and shank portion of the hook itself. The Inspection Hook is suitable for applications where inspection of the internal parts of the hook set is required. The inspection hook uses the standard Harrington hook set and is assembled with high-strength locking fasteners instead of rivets. Inspection hooks are available in top and bottom versions. Refer to Figure 2-5.
3.0 Preoperational Procedures 3.1 Chain 3.1.1 Verify that the load chain is not twisted or tangled prior to operating the hoist. Make sure the bottom hook on the 2 (CF020) through the 5 (CF050) Ton multiple fall hoists is not capsized. See Figures 3-1 and 3-2. Correct all chain irregularities before conducting the first hoist operation.
3.2 Attachment Points 3.2.1 Prior to attaching the hoist ensure that all attachment points, suspension components and supporting structure are adequate to support the hoist and its load. If necessary consult a professional that is qualified to evaluate the adequacy of the suspension location and its supporting structure. 3.2.2 3.3 3.4 See Section 6.6 for outdoor installation considerations. Mounting the Hoist 3.3.
4.0 Operation 4.1 Introduction DO NOT WALK UNDER A SUSPENDED LOAD HOIST OPERATORS SHALL BE REQUIRED TO READ THE OPERATION SECTION OF THIS MANUAL, THE WARNINGS CONTAINED IN THIS MANUAL, INSTRUCTION AND WARNING LABELS ON THE HOIST OR LIFTING SYSTEM, AND THE OPERATION SECTIONS OF ANSI/ASME B30.16 and ANSI/ASME B30.10. THE OPERATOR SHALL ALSO BE REQUIRED TO BE FAMILIAR WITH THE HOIST AND HOIST CONTROLS BEFORE BEING AUTHORIZED TO OPERATE THE HOIST OR LIFTING SYSTEM.
4.2 Shall’s and Shall Not’s for Operation Improper operation of a hoist can create a potentially hazardous situation which, if not avoided, could result in death or serious injury, and substantial property damage. To avoid such a potentially hazardous situation THE OPERATOR SHALL: • NOT lift more than rated load for the hoist. • • NOT use damaged hoist or hoist that is not working properly. NOT leave load supported by the hoist unattended unless specific precautions have been taken.
Improper operation of a hoist can create a potentially hazardous situation which, if not avoided, could result in minor or moderate injury, or property damage. To avoid such a potentially hazardous situation THE OPERATOR SHALL: • Maintain a firm footing or be otherwise secured when operating the hoist. • Check brake function by tensioning the hoist prior to each lift operation. • Use the hoist manufacturer’s recommended parts when repairing the unit. • Use hook latches.
5.0 Inspection 5.1 General 5.1.1 5.2 The inspection procedure herein is based on ANSI/ASME B30.16. The following definitions are from ANSI/ASME B30.16 and pertain to the inspection procedure below.

6.0 Maintenance and Handling 6.1 Lubrication 6.1.1 Load Chain For longer life, the load chain should be lubricated. The load chain lubrication should be accomplished after cleaning the load chain with an acid free cleaning solution. Apply Harrington lubricating grease (Part No. ER1BS1951) or an equivalent to industrial general lithium grease, NLGI No. 0, to the bearing surfaces of the load chain links as indicated by the shaded areas in Figure 6-1.
6.2 Disassembly, Assembly and Adjustment 6.2.1 1) Perform proper disassembly or assembly in accordance with this manual. 2) The hoist utilizes dry friction plates; they are not to be lubricated. 3) Do not extend the load chain. 4) Remove old grease on the disassembled parts. 5) Replace components with Harrington Hoist approved parts. 6) To reassemble, apply new grease, and use a new split pin and snap ring. 6.2.2 Tools – The following tools are required to disassemble/reassemble the hoist. No.
NOTE: The pawl pin is fixed with the U nut [25]. 11) Unscrew four socket bolts [22, 22-A] connecting body A [10] and B [11]. NOTE: Four socket bolts are fixed with U nuts [23] on the body B side. 12) Separate the body A [10] and B [11]. 13) Take ball bearing A [15] and C [17-A] out of the body A [10] (only if bearing needs replaced). 14) Remove the top hook [1] and top pin [3] from the body B [11].
6) Insert the end of the load chain [42] to the bottom hook [4] and fix them with the chain pin [7], slotted nut [8] and split pin [9]. For Bullard , Shur-loc , or Inspection type hooks, refer to Table 63 for yoke nut torque specifications. : Always bend the split pin securely. Figure 6-3 Bottom Hook Assembly 7) Place the load chain [42] on the load sheave [18] so that the bottom hook side comes to right hand and the end link of the other side becomes vertical to the load sheave pocket.
Figure 6-5 Chain Guide Assembly 12) Clean and grease ball bearing A [15] and D [17-A] and insert into body A [10] (if being replaced). 13) Put the body A [10] with the ball bearings [15, 17-A] side down on the body B [11]. : Make sure each part is completely set between body A [10] and frame [13]. 14) Insert four socket bolts [22, 22-A] into the body A [10] and turn the whole body sideways. Then fix the bolts with the U nuts [23] holding the U nuts with fingers.
17) Thread friction disc [29] on the pinion [14]. 18) Wipe out any dirt on the friction disc [29], friction plates [32] and both sides of the ratchet disc [30] and make sure that bushing [31] is properly soaked with oil. Then place the friction plate, bushing, ratchet disc (while the pawl [27] is rotated counterclockwise), and friction plate respectively on the friction disc. (Make sure that the pawl meshes with the ratchet disc properly.) : NEVER apply oil since the brake is a “dry system”.
Figure 6-8 Hand Wheel Assembly 22) Put wheel cover [37] on the body A [10] and fix them with the spring washers [39] and screws [38]. 23) Put a hoist with body B [11] side up. Place the slack end of the load chain between body A [10] and body B [11]. Then insert tail pin [40], and screw tap socket bolt [41] into the body B. : Make sure the load chain is not twisted. Be careful not to cross thread or over torque tap socket bolt [41].
6.5 Storage 6.5.1 : IMPROPER chain hoist use could result in death or serious injury. To avoid these hazards: 6.6 ALWAYS store the hoist in a no load condition. ALWAYS wipe off all dirt and water. ALWAYS oil the chain, hook pins and hook latches. ALWAYS hang in a dry place. ALWAYS check the hoist for abnormalities (according to the regular inspection procedures) when using the hoist after a period of non-use (Refer to section 5.5). Outdoor Installation 6.6.
7.0 Troubleshooting Read and comply with instructions in this manual and use the hoist properly. Checking the sounds from the hoist in operation is a critical inspection. Note hoist sounds during operation. If a defect is found in the hoist, stop using it immediately and check the cause of the defect. Only Trained and competent personnel should inspect and repair the hoist.
Table 7-1 Troubleshooting Guide Symptom Cause Remedy Reassemble properly and ensure proper lifting before reuse. During operation, hoist idles or load drifts Poor load sheave and load chain contact caused by improper chain-reeving. Reset the capsized hook. Hoist will not lift all the way (multiple fall hoists) Capsized hook Twisted Chain Capsized Hook and Chain Double Fall Models Hoist does not lift load smoothly. Improper assembly of gear OR bearing broken.
Table 7-1 Troubleshooting Guide Improper braking may cause improper load lowering. The hoist utilizes dry friction discs; do not apply oil to friction surfaces. Symptom Cause Remedy Over tightened brake The hoist left under load for a long period Load will not go down Pull down hard (possibly with 2 people) on the hand chain to loosen brake. Shock loaded during operation Brake rusted tight Replace the rusty components and perform hoist maintenance.
