The manual portable gantry crane is a kind of light lifting equipment, consisting of two columns and a beam. It is shaped like a gantry and can be manually operated for lifting and carrying heavy objects. It is usually made of lightweight materials and is compact, making it easy to carry and move. Manual portable gantry cranes are flexible and adaptable and can be adjusted as needed, making them suitable for some occasions that require temporary lifting. Operators use devices such as manual hoists or hand hoists to perform lifting operations through connecting objects such as ropes or chains. This type of gantry crane usually has a smaller lifting capacity and is suitable for lighter cargo handling tasks.
Manual portable gantry crane is mainly composed of lifting beam, bracket, hand chain hoist, chain, etc. Among them, the hanging beam is the main body of the entire equipment, used to support and fix other components; the bracket plays the role of connecting the hanging beam and the hand chain hoist to ensure the stability and safety of the equipment; the hand chain hoist is the core component of the equipment. The transmission of the chain realizes the lifting and lowering of heavy objects; the chain is one of the key components of the equipment, and the transmission of the chain drives the movement of heavy objects.
The working principle of the manual portable gantry crane is mainly to move heavy objects through the lifting and lowering of the hand chain hoist and the transmission of the chain. Specifically, the operator pulls the chain of the chain hoist to rotate the internal gear of the chain hoist, thereby driving the chain transmission to realize the lifting and movement of heavy objects. The working principle of this equipment has the advantages of simplicity, convenience, flexibility, etc., and can adapt to various working environments and needs.
● It has the advantages of convenience and flexibility, and can adapt to various working environments and needs.
● It can be used to lift goods, equipment, machinery, etc. and can be easily moved and repositioned.
● All components of the equipment have undergone strict quality testing and safety assessment to ensure the safety and stability of the equipment.
● No large infrastructure support is required, and no additional installation and maintenance costs are required, so the economic investment is small.
Precautions for use:
● Load Limit: Manual portable gantry cranes have their designed load limits, do not exceed their rated load capacity. Before use, make sure to understand the load capacity of the equipment and operate it strictly in accordance with the specified load range.
● Stable ground: Ensure that the manual portable gantry crane is placed on a stable and solid ground to ensure the stability and safety of the equipment. If the ground is uneven or unstable, appropriate measures should be taken to level or secure it.
● Proper Installation: When installing a manual portable gantry crane, follow the installation instructions provided by the manufacturer. Make sure the connection between the columns and beams is firm and the bolts are tightened reliably.
● Operator training: Only personnel who have been trained and familiar with operating procedures can operate manual portable gantry cranes. Operators should understand the working principle, operating methods and safety precautions of the equipment, and operate in strict accordance with the operating procedures.
● Check equipment: Before each use, check whether all parts of the manual portable gantry crane are intact, especially whether ropes, chains, hoists and other lifting devices are operating normally and whether there is any abnormal wear or damage.
● Pay attention to safety distance: During lifting operations, make sure there are no people or obstacles around to avoid accidental injuries. Set up a cordon or safe area to restrict entry by non-relevant personnel.
● Regular maintenance: Regular inspection and maintenance of manual portable gantry cranes, including lubricating parts, fastening bolts, lifting devices, etc. If abnormalities or failures are found, they should be repaired or replaced in time.
