Stainless steel lever crane, as an efficient and durable lifting equipment, is widely used in multiple industrial fields. The following is a detailed introduction to its characteristics, application scope, and operating rules:

1、 Product Features

Corrosion resistance and high strength:

Made of 304 or 316 stainless steel, it effectively resists corrosion in humid, acidic, alkaline, and salt spray environments, and is suitable for high corrosion scenarios such as chemical and marine engineering.

After heat treatment, stainless steel material has both toughness and hardness, ensuring that the equipment is not easily deformed under heavy loads.

Leverage operation design:

By amplifying the operating force through the principle of leverage, it only requires a small amount of manpower to achieve smooth lifting and lowering of heavy objects, thereby improving work efficiency.

The lever stroke can be fine tuned to achieve precise control and avoid impact loads.

Precision transmission system:

Equipped with high-precision alloy steel gears that have undergone quenching treatment, they have strong wear resistance and high transmission efficiency.

The reinforced chain is made of high-strength alloy steel material, with surface galvanized or stainless steel treatment, high tensile strength, and long service life.

Dual braking system:

Mechanical braking: Real time braking is achieved through a ratchet and pawl structure to prevent heavy objects from sliding down.

Friction braking: equipped with friction disc brakes, which automatically lock in case of overload to ensure safety.

Security performance:

Overload protection: When the load exceeds the rated value, the braking system triggers and stops the lifting operation.

Limit device: Using mechanical or electronic limit switches to prevent excessive stretching or derailment of the chain.

Anti reverse design: The gear structure ensures that it can only rotate in one direction, avoiding accidental operation that may cause heavy objects to lose control.

Environmental adaptability:

High temperature resistance: It can work normally in environments ranging from -30 ℃ to 120 ℃ and adapt to extreme temperature scenarios.

Dustproof and Waterproof: Some models have reached the IP55 protection level, which can resist the intrusion of rainwater and dust.

Portable design: small size, light weight, equipped with a carrying handle, convenient for outdoor operations.

Low maintenance requirements:

Self lubricating bearings: Oil containing bearings are used to reduce lubrication frequency and maintenance costs.

Modular design: Key components can be quickly replaced, reducing maintenance time.

Fatigue resistant structure: The combination of stainless steel material and high-strength chain can withstand tens of thousands of lifting cycles.

2、 Application scope

Stainless steel lever cranes are widely used in the following fields due to their corrosion resistance, high strength, safety and reliability characteristics:

Chemical and Pharmaceutical:

Safely handle raw materials or finished products in corrosive environments, in compliance with hygiene standards.

Food processing:

Used for material lifting in production lines, pollution-free and easy to clean, meeting the strict requirements of the food processing industry.

Ship and Ocean Engineering:

Resistant to seawater corrosion, suitable for shipyard maintenance, offshore platform operations, and other scenarios.

Architecture and Decoration:

Portable design suitable for high-altitude operations, such as glass curtain wall installation, steel structure hoisting, etc.

Oil and gas:

Perform equipment maintenance and material handling in corrosive environments to ensure operational safety.

Power Engineering:

Suitable for equipment installation and maintenance in power plant construction, ensuring the smooth progress of power engineering.

3、 Operation rules

To ensure the safe and efficient operation of stainless steel lever cranes, operators must strictly follow the following rules:

Pre use inspection:

Appearance and structure: Check whether there are cracks, deformations, or welding defects in the crane body, hook, and chain; Confirm if the connecting components (such as bolts, pins) are loose or missing.

Chain and hook: measure the diameter of the chain or check for obvious stretching or twisting; Check whether the hook is deformed or cracked, whether it rotates flexibly, and whether the safety buckle is intact.

Braking system: In the unloaded state, slowly release the lever and observe whether the brake can immediately stop the chain movement; Check if the gap between the brake pads and brake wheels meets the requirements of the instruction manual.

Lubrication and corrosion: Check the lubrication condition of key parts such as gears, bearings, and chains, and supplement or replace lubricating oil if necessary; Check for localized corrosion or chemical damage to stainless steel components.

Operating mechanism: Check whether the lever rotates flexibly without any jamming phenomenon; Test whether the upper and lower limit switches are effective.

Environment and load: Confirm that the equipment is placed on a hard and flat surface, avoiding tilting or sinking; Check if the load weight is within the rated range of the crane and verify if the load is balanced.

Precautions during operation:

Slow start, avoid emergency stop or rapid reverse operation, and reduce impact torque.

Observe the operation status of the equipment and pay attention to whether there is any abnormal noise, vibration, or oil leakage.

Maintain a safe distance and avoid being under loads or within the trajectory of equipment movement.

Post operation maintenance:

Clean equipment, remove dirt or impurities from chains and gears, and prevent corrosion.

Record the load weight, time, and any abnormal situations of this operation for easy tracking of equipment status.

Special environmental precautions:

Low temperature and freezing weather: Strengthen equipment inspection, equip snow removal equipment and anti slip materials; Avoid using or take measures to prevent wind and slip.

Rainstorm and flood: no open operation; Inspect drainage facilities and repair damaged components.

Typhoon: Lock the anchoring device and stop operation; Check and clean the equipment to ensure safety.

High temperature and scorching heat: avoid working during high temperature periods; Pay attention to the cooling of hydraulic systems and electrical components.
