Description
10 ton hand chain hoist is a kind of mechanical lifting equipment to realize the vertical lifting of heavy objects through human operation, adopting modular lever principle and double ratchet braking system, which can complete the lifting of heavy materials without electricity. With EN 13157 safety certification, it is widely used in factory equipment maintenance, ship construction, steel structure installation and other scenarios.
Material: G80 alloy steel (tensile strength ≥800MPa), carburized quenching + galvanized passivation treatment, wear resistance and corrosion resistance increased by 50%.
Safety factor: 4:1 breaking load design, single chain limit load up to 40 tons, far more than the industry 6 times safety redundancy standards.
Chain link specifications: Φ10mm×30mm calibrated links with built-in self-lubricating bushings to reduce friction loss.
Anti-collision and anti-drop structure
Dual shell structure: outer steel plate stamping shell (thickness 2.5mm) + inner nylon gear cover, realizing IP44 protection level.
Dustproof design: labyrinth sealing structure prevents dust from entering the key transmission parts, prolonging the service life of the equipment.
Ergonomics: Curved handle grips covered with non-slip rubber reduces pulling force requirements to 35kg (ISO 9374 compliant).
Self-locking safety hook
Manufacturing process: Die forging + full-perimeter ultrasonic flaw detection, eliminating the internal porosity defects of traditional cast hooks.
Safety Tongue: Spring-loaded tongue auto-locking device prevents accidental unhooking of sling/chain.
Swivel function: 360°swivel hook head equipped with thrust bearing, load swing is reduced by 70%.
Utilization Features
No power dependence: Purely mechanical transmission allows safe operation in special environments such as flammable and explosive, high humidity, etc.
Precise fine-tuning: 0.5mm level hand-pull stroke control to meet the needs of precision equipment installation and positioning.
Quick disassembly and assembly: modular components support guide rail/fixed bracket installation in multiple scenarios (adapted to I-beam 200-400mm).
Emergency brake: double pawl brake + friction plate overload protection system, sudden chain release response time <0.3 seconds.
Low maintenance cost: only need monthly chain lubrication maintenance, annual maintenance cost <2% of the value of the equipment
