Application areas and product description of Running Crane Manual Holist

1、 Application Fields

Industrial manufacturing and warehousing

Scenario: Factory workshops, warehouses, logistics centers, and other places that require frequent handling of heavy objects.

Purpose: For lifting steel, mechanical equipment, containers, etc., suitable for areas with limited space or inconvenient power supply.

Advantages: No need for electricity, relies on manual operation, suitable for light to medium loads (usually 0.5-10 tons), low cost and simple maintenance.

Architecture and Construction

Scenario: Construction sites, bridge construction, high-rise building construction, etc.

Purpose: Vertical lifting of building materials (such as steel bars, concrete blocks), installation of equipment, or temporary lifting operations.

Advantages: Strong portability, can be moved with the project, suitable for outdoor or harsh environments.

Automotive Maintenance and Shipbuilding Industry

Scene: Car repair shop, shipyard, dock, etc.

Purpose: To hoist engines, marine components, or perform equipment maintenance.

Advantage: Precise control of load position, suitable for operating in narrow spaces.

Emergency rescue and temporary operations

Scenario: Disaster rescue, temporary stage construction, outdoor activities, etc.

Purpose: Quickly deploy lifting equipment to respond to power outages or emergency situations.

Advantages: No need for additional energy, flexible operation.

2、 Product Description

Structure and Working Principle

Composition: It consists of an upper hook (connecting the supporting structure), a lower hook (connecting the load), a sprocket or pulley, a gear transmission system, a braking device, and a housing.

Driving method: By manually pulling the chain or handle, the gear is rotated to achieve the lifting and lowering of the load.

Braking system: Mechanical braking (such as ratchet braking) is used to ensure that the load remains stable and does not slide when stopped.

Type and specifications

Chain Block:

Features: Chain driven, suitable for vertical lifting, easy to operate.

Specification: The common load range is 0.5-20 tons, and the chain length can be customized.

Hand cranked hoist:

Features: Leveraged operation, which can achieve fine adjustment of load and horizontal traction.

Specification: Load range of 0.25-9 tons, suitable for multi angle operation.

key parameters

Load capacity: Depending on the model, it usually covers 0.5-20 tons.

Lifting speed: manual operation, slow speed (about 0.1-0.5 meters/minute), but highly controllable.

Headroom: The minimum distance between the upper and lower hooks, which affects the use in low spaces.

Safety factor: usually designed at 4:1 or 5:1 to ensure safety during overloading.

Advantages and limitations

Advantage:

No need for electricity: suitable for environments without power or flammable and explosive materials.

Portability: Small size, light weight, can be carried around or quickly deployed.

Low cost: The purchase and maintenance costs are much lower than those of electric hoists.

Precise control: Manual operation can achieve fine adjustment and positioning of the load.

limitations:

High labor intensity: Long term operation is prone to fatigue and is not suitable for high-frequency or overweight loads.

Slow speed: lower efficiency than electric or pneumatic hoists.

Load limit: Usually not applicable to heavy lifting exceeding 20 tons.

3、 Selection and usage suggestions

Load matching: Select models with appropriate load capacity based on job requirements to avoid overloading.

Space adaptability: Confirm whether the head distance meets the requirements of the working height, especially in low and low environments.

Operation training: Ensure that operators are familiar with the use and safety regulations of manual hoists.

Maintenance: Regularly inspect chains, gears, and braking devices, lubricate moving parts to extend their service life.
