Product Detail

HSZ-C Triangular Manual Chain Hoist Description

HSZ-C Series Triangular Manual Chain Hoist from Benteng Hoist is a heavy-duty, hand-operated lifting device designed for high-intensity industrial operations where power sources are unavailable or impractical. Featuring a classic triangular casing design, this robust manual chain block offers optimal structural stability and efficient force distribution, protecting internal transmission gears from impact and harsh weather conditions during outdoor field projects.

Constructed with high-strength alloy steel hooks, a heat-treated G80 grade manganese load chain, and a sensitive dual-pawl braking system, this high-performance hand operated hoist ensures precise load positioning while preventing accidental slipping. Compatible with I-beam trolleys, monorail cranes, and temporary rigging frames, the triangular manual chain hoist delivers high portability, low maintenance, and smooth mechanical lifting across a wide variety of industrial environments.

Key Advantages of HSZ-C Triangular Chain Hoist

High-Stability Triangular Design: The triangular outer casing provides excellent structural rigidity and uniform stress distribution, enhancing overall unit durability during demanding lifts.
Heavy Duty Capacities (0.5T to 20T): Complete tonnage coverage from 0.5 Ton to 20 Tons meets versatile lifting requirements across workshops, civil engineering, and equipment maintenance.
Reliable Dual-Pawl Braking System: Built-in double pawl automatic braking mechanism reacts instantly when operation stops, ensuring steady holding and precise load control.
Wear & Corrosion Resistant G80 Chain: Premium G80 alloy load chain combined with forged alloy steel hooks delivers superior tensile strength and continuous operational safety under load.
Zero-Power & Flexible Rigging: Operates entirely by hand, making it a portable choice for off-grid construction sites, confined utility vaults, and outdoor plant overhaul operations.

Internal Structure

High-Strength Alloy Steel Hook: Drop-forged from high-grade alloy steel, designed to yield gradually under extreme overload rather than fracture suddenly, ensuring site safety.
Thickened Triangular Alloy Steel Casing: Deep-drawn, reinforced alloy steel shell that protects the internal spur gears, drive shaft, and chain guide wheel from impact damage and abrasive dust.
G80 Grade Manganese Steel Load Chain: High-tensile, heat-treated G80 alloy steel chain engineered for long operational life, high strength, and resistance against surface wear.
Safety Latch (Insurance Buckle): Heavy-duty spring-loaded latch on top and bottom hooks to secure slings and prevent unintended disengagement during lifting operations.

Safety Testing & Quality Control

As a dedicated manual chain block manufacturer, Benteng implements strict quality verification procedures across every manufacturing batch:

Factory Proof-Testing: Every unit is subjected to rated load tests and up to 125%–150% overload proof tests prior to final inspection and packing.
Component Metallurgical Inspection: All G80 load chains, drop-forged hooks, spur drive gears, and braking pawls undergo dimensional checks and hardness testing.
Braking & Hold Verification: Both static and dynamic braking systems are tested under load to ensure instant ratchet engagement and zero slippage.

OEM Customization & B2B Solutions

Benteng Hoist provides full OEM and private-label manufacturing options for global lifting gear distributors and procurement specialists:

Custom Chain Lengths: Tailored load chain and hand chain lift heights (e.g., 3m, 6m, 9m, 12m, or longer) according to job site parameters.
Integrated Overload Limiter: Optional mechanical friction clutch to prevent operation beyond the rated capacity limit.
Custom Powder Coating & Branding: Customized housing colors, private-label metal plates, and branded export packaging.
Beam Trolley Integration: Pre-assembled packages with push or geared monorail trolleys for horizontal beam travel.

Frequently Asked Questions

Q1: What is the main structural advantage of a triangular manual chain hoist?

A: The triangular casing layout offers high structural rigidity and even stress distribution across the chassis, providing effective impact resistance and gear protection in heavy-duty construction environments.

Q2: How does the dual-pawl braking system function?

A: The dual-pawl mechanism utilizes two independent pawls engaging with the ratchet wheel. When hand chain pulling stops, the pawls engage immediately, holding the load firmly at the desired height without slipping.

Q3: Can the HSZ-C chain hoist be used with an I-beam trolley?

A: Yes. The top hook easily connects to manual push trolleys or geared monorail trolleys, enabling both vertical lifting and horizontal movement along I-beams or overhead crane tracks.

Q4: Can the load chain lift height be customized for special construction requirements?

A: Yes. Benteng Hoist supplies customized G80 load chain lengths to match any specific vertical lifting height required for deep shaft or elevated rigging projects.
