- Smooth Operation: Hardened steel wheels and double-sealed lubricated ball bearings provide smooth movement.
- Adjustable Design: Easily adjustable to various beam types (wide-flange H-beams, standard I-beams, or curved track) using included spacer washers.
- Compliance: Complies with OSHA Regulations, ANSI / ASME B30.11 and B30.17 standards.
2. Safety Information
Always prioritize safety when operating heavy lifting equipment. Failure to follow safety guidelines can result in serious injury or property damage.
- Read Instructions: Read and understand this entire manual before installation or operation.
- Load Capacity: Never exceed the rated 1/2-ton (1000 lbs) load capacity of this trolley.
- Beam Inspection: Ensure the supporting beam is structurally sound, free of defects, and rated to handle the intended load plus the weight of the trolley and hoist.
- Proper Installation: Install the trolley correctly on the beam, ensuring all fasteners are tightened and cotter pins are in place.
- Clear Area: Keep the work area clear of personnel and obstructions during operation.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety glasses, gloves, and steel-toed boots.
- Avoid Shock Loading: Do not drop or suddenly apply loads to the trolley. Lift and lower loads smoothly.
- Regular Inspection: Inspect the trolley, beam, and any attached lifting devices before each use for wear, damage, or loose components.
3. Setup
Proper setup is crucial for the safe and effective operation of your JET Manual Trolley.
- Beam Selection: Identify a suitable I-beam, H-beam, or curved track that is structurally capable of supporting the trolley and its maximum intended load. The beam must be clean and free of debris.
- Trolley Disassembly: Remove the end bolt and spacer washers from one side of the trolley to allow it to be placed onto the beam flange.
- Positioning on Beam: Carefully place the trolley onto the beam flange.
- Adjusting Beam Flange Width: The trolley is designed with multiple spacer washers to accommodate various beam flange widths. Select the appropriate number of spacer washers to ensure a snug fit, allowing for smooth movement without excessive side-to-side play. The goal is to minimize lateral movement while ensuring the wheels roll freely.
- Reassembly: Reinsert the end bolt and secure it with the cotter pin. Ensure the cotter pin is fully engaged to prevent the bolt from loosening during operation.
- Final Check: After assembly, manually push the trolley along the beam to confirm smooth movement and proper fit. Verify that the attachment point for your hoist or winch is securely fastened to the trolley's lower eyelet.
4. Operating Instructions
Follow these steps for safe and efficient operation of your manual trolley:
- Pre-Operation Check: Before each use, inspect the trolley, beam, and attached hoist/winch for any signs of wear, damage, or loose components. Ensure the beam is clean and free of obstructions.
- Attach Load: Securely attach your load to the hoist or winch, which is then connected to the trolley's lower eyelet. Ensure the load is balanced.
- Lift Load: Use the hoist or winch to lift the load slightly off the ground.
- Move Load: Gently push or pull the load to move the trolley along the beam. Avoid sudden jerks or excessive force. The hardened steel wheels and lubricated ball bearings are designed for smooth movement, provided the beam surface is clean.
- Position Load: Guide the load to its desired position.
- Lower Load: Slowly and carefully lower the load using the hoist or winch.
- Post-Operation: Once the task is complete, remove the load and store the trolley and hoist in a safe, dry place.
5. Maintenance
Regular maintenance will ensure the longevity and safe operation of your JET Manual Trolley.
- Cleanliness: Keep the beam and trolley wheels clean and free of dirt, grease, or debris that could impede smooth movement.
- Lubrication: The double-sealed ball bearings are lubricated for life and generally do not require additional lubrication. However, periodically check for any signs of stiffness or unusual noise, which may indicate a need for professional inspection.
- Fastener Check: Periodically check all bolts, nuts, and the cotter pin for tightness. Tighten any loose fasteners.
- Wear Inspection: Inspect the wheels, axles, and side plates for signs of wear, cracks, or deformation. Pay close attention to the bumper guards for any damage. Replace any worn or damaged parts immediately.
- Storage: Store the trolley in a dry environment to prevent rust and corrosion.
6. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Trolley does not move smoothly | Dirty beam surface; incorrect beam flange width adjustment; damaged wheels/bearings. | Clean the beam surface. Adjust spacer washers for proper fit. Inspect and replace damaged wheels or bearings. |
| Excessive side-to-side movement | Beam flange width not properly adjusted. | Add or remove spacer washers to achieve a snug fit on the beam flange. |
| Unusual noises during operation | Worn bearings; loose components; foreign object on beam. | Inspect bearings for wear. Check all fasteners for tightness. Clear beam of any obstructions. |
| Trolley jams or binds | Damaged beam; misaligned beam; excessive load. | Inspect beam for damage or misalignment. Ensure load does not exceed capacity. |
