Synchronous Lifting Electric Hoist

Synchronous Lifting Electric Hoist Overview

Synchronous Lifting Electric Hoist (DHP Series) is a heavy-duty material handling system specifically engineered for large-scale, multi-point collaborative lifting operations. Integrating precision alloy ring-chain transmission with advanced multi-machine synchronous control technology, this robust electric chain hoist enables synchronized lifting and lowering of massive industrial structures without stress concentration, load tilt, or differential displacement.

As a qualified supplier and global exporter, we engineer the DHP group lifting series for demanding high-altitude construction and heavy structural assembly. It serves as the industry-standard lifting system for climbing scaffolding in high-rise building construction, large oil storage tank welding and jacking, ship section alignment, and heavy steel bridge segment erection.

Key Advantages & Engineering Excellence

• High Synchronization Accuracy: Uniform operating speeds across multiple linked hoists eliminate uneven load distribution, structural strain, and dynamic displacement during collaborative lifts.

• Disc Braking System: High-performance disc brake engages instantly upon stopping, delivering zero load slippage and millimeter-precise holding stability under heavy static loads.

• High Structural Safety Margin: Built with Grade 80 heat-treated alloy steel load chains and drop-forged manganese steel hooks, providing a elevated safety factor for high-altitude multi-point lifting.

• Compact & Lightweight Architecture: High power-to-weight ratio allows flexible deployment and easy handling within tight building gaps, climbing frame rails, and restricted storage yards.

• Low-Noise & Long Service Life: Heavy-duty gear reduction mechanisms running in sealed lubrication environments ensure minimal tooth wear and ultra-low noise during long-term continuous duty.

Core Application Scenarios

The synchronous lifting electric hoist provides specialized multi-point lifting capabilities across critical construction and industrial engineering sectors:

1. High-Rise Construction & Climbing Scaffolding

The DHP series is the premier choice for synchronized climbing frames and climbing formwork in high-rise building construction. Multiple linked hoists raise large external scaffolding sections smoothly in unison, eliminating the need to repeatedly re-erect scaffolding at increasing building heights and drastically lowering high-altitude operational costs.

2. Large Storage Tank & Vessel Construction

A standard solution for field-welding and jacking large petroleum storage tanks and liquid gas vessels. Multiple synchronized DHP hoists perform uniform perimeter lifting and precise alignment of heavy tank shells with balanced load distribution.

3. Structural Steel Bridges & Ship Section Alignment

Delivers reliable multi-point elevation control for bridge deck segment lifting, large steel frame splicing, and shipyard hull section positioning where precise alignment is paramount.

4. Compact Workshop Assembly & Warehousing

The compact footprint and low-speed, smooth hoisting characteristics suit confined assembly bays, mold maintenance stations, and high-frequency warehouse loading applications requiring stable, low-sway handling.

Complete Multi-Layered Safety Protection

Operating group-lifting machinery in high-altitude environments requires absolute operational safety:

1. Integrated Thermal Motor Protection: Prevents motor burnout during continuous group-lifting operations under elevated ambient temperatures.

2. Upper & Lower Limit Switches: Automatically disengages motor power at critical travel limits to prevent chain jamming or housing collision.

3. Drop-Forged 360° Swivel Hooks: High-tensile manganese steel hooks feature heavy-duty safety latches and 360-degree rotation to eliminate load chain twisting.

4. Centralized Master Control Panel Compatibility: Easily integrated into centralized multi-channel control panels for unified button control and emergency stop execution across all connected units.

Frequently Asked Questions

Q1: Why is the DHP series hoist preferred over standard hoists for climbing scaffolding?

A: Standard hoists may operate at slightly varying motor speeds, causing uneven lifting and structural binding. The DHP series features synchronized motor characteristics and disc brakes to guarantee consistent, uniform elevation across all climbing points.

Q2: Can individual hoists in a DHP group system be controlled independently?

A: Yes. When paired with our master group control panel, operators can control all hoists synchronously or switch to individual control for precise single-point leveling and adjustment.

Q3: How does the disc brake perform during a power failure?

A: The automatic disc brake system is fail-safe; it engages instantly upon power interruption, locking the load in position without slippage or drifting.
