اطلاعات ایمنی

Always prioritize safety when operating lifting equipment. Failure to follow these safety guidelines can result in serious injury or property damage.

• محدودیت ظرفیت: Never exceed the rated capacity of 2200 lbs (1000 kg). Overloading can cause hoist failure.
• بازرسی: Before each use, inspect the hoist, load chain, and hooks for any signs of wear, damage, or deformation. Do not use if any defects are found.
• Load Security: Ensure the load is properly secured and balanced before lifting. The load hook must be fully engaged with the load.
• Hook Safety Latches: Always ensure hook safety latches are functional and properly closed. Ductile drop-forged hooks are designed to show noticeable opening if subjected to excessive overload, indicating a need for replacement.
• محیط عملیاتی: Use the hoist in a clear area, free from obstructions. Keep hands and body clear of the load and moving parts.
• انطباق استاندارد: This hoist meets ASME B30.21/HST-3 safety standards and has a safety coefficient of at least 4:1.
• مدیریت زنجیره: Ensure the load chain is free of twists, kinks, or knots before and during operation.
• پرسنل: Only trained and authorized personnel should operate the hoist.

اجزای محصول

Familiarize yourself with the main components of your lever chain hoist:

1. قلاب بالایی: Used for attaching the hoist to a secure anchor point.
2. دسته اهرمی: Used to operate the lifting and lowering mechanism.
3. Control Lever/Selector: Switches between UP, NEUTRAL, and DOWN modes.
4. Hoist Body/Gear Case: Houses the internal lifting mechanism and brake system.
5. زنجیر بار: Grade 80 chain that supports and moves the load.
6. قلاب پایینی: Used for attaching to the load.

راه اندازی

تنظیم صحیح برای عملکرد ایمن و کارآمد بسیار مهم است.

1. Secure Anchor Point: Attach the upper hook of the hoist to a structural member or trolley that is rated to safely support the hoist's weight plus the maximum intended load. Ensure the anchor point is stable and secure.
2. Hoist Orientation: Ensure the hoist hangs vertically and the load chain is free to move without obstruction.
3. بازرسی زنجیره ای: Pull the load chain through the hoist to ensure it moves freely and is not twisted or kinked.
4. عملیات تست: Before attaching a load, perform a few cycles of lifting and lowering with no load to confirm smooth operation of the lever and chain.

دستورالعمل های عملیاتی

Follow these steps for safe lifting and lowering operations.

Lifting a Load

1. بار ضمیمه: Securely attach the lower hook to the load. Ensure the safety latch is closed.
2. Select UP Mode: Move the control lever to the "UP" position.
3. Operate Lever: Pump the lever handle up and down to lift the load. Each stroke will raise the load incrementally. Maintain a steady, controlled motion.
4. بار مانیتور: Continuously observe the load and hoist for any signs of instability or strain.

کاهش بار

1. Select DOWN Mode: Move the control lever to the "DOWN" position.
2. Operate Lever: Pump the lever handle up and down to lower the load. The speed of lowering is controlled by the rate of pumping.
3. فرود کنترل شده: Lower the load slowly and steadily to its desired position.

Free Chaining (No Load)

To quickly adjust the chain length without a load:

1. Select NEUTRAL Mode: Move the control lever to the "NEUTRAL" position.
2. تنظیم زنجیر: Manually pull the load chain to the desired length. This mode disengages the brake, so ensure there is absolutely no load on the hook.
3. Re-engage: Return the control lever to "UP" or "DOWN" before applying any load.

تعمیر و نگهداری

نگهداری منظم، طول عمر و عملکرد ایمن بالابر شما را تضمین می‌کند.

• روغن کاری: Periodically lubricate the load chain and internal mechanisms with lithium grease or a similar high-quality lubricant. Refer to the manufacturer's recommendations for specific lubrication points and frequency.
• بازرسی زنجیره ای: Regularly inspect the entire length of the load chain for wear, corrosion, nicks, gouges, or stretched links. Replace the chain if any damage is found.
• بازرسی قلاب: Check both upper and lower hooks for deformation, cracks, or excessive wear, especially at the throat opening. Ensure safety latches operate freely and fully close.
• سیستم ترمز: The heat-treated double pawl, 3-piece disc brake system is designed for reliability. If the brake feels less responsive, have it inspected by a qualified technician.
• تمیز کردن: Keep the hoist clean and free from dirt, debris, and corrosive materials.
• ذخیره سازی: Store the hoist in a dry, clean environment when not in use.
