DH650 Tower Crane | DAHAN Technology

Product Overview

The DH650 luffing jib tower crane is independently developed and manufactured by DAHAN Technology. It is widely used in super high-rise construction, large bridge projects, municipal infrastructure and crowded downtown construction sites. This tower crane features flexible jib assembly options, powerful lifting performance, stable structural design and easy installation & maintenance, perfectly solving space restriction problems in compact construction yards.

The unit supports multiple jib length selections, matched lifting height schemes and dedicated counterweight configurations, with a maximum rated lifting load of 45t. Standardized mast sections and anchoring attachment systems ensure high safety and long-term stable operation.

Structural Component Introduction

1. Overall Outline Dimensions

The dimension drawing marks the full machine layout, maximum & minimum working radius under working and non-working status, luffing angle range and overall external dimensions with precise meter units, supporting foundation design, site layout and space collision checking directly.

2. Standard Tower Mast Section

High-rigidity integrated standard mast sections adopt unified splicing dimensions, featuring strong vertical bearing capacity, fast assembly speed and reliable long-term bearing performance, which greatly shortens tower erection cycle.

3. Anchorage Attachment System

Multiple sets of attachment schemes are reserved for high-rise climbing construction, with clear attachment spacing and installation dimensions. The attachment frame effectively lowers the free-standing height and significantly improves overall tower stability for high-rise construction.

Load Characteristic Performance

The official complete load table records exact lifting capacity corresponding to each working radius (15m–65m) under different jib lengths. Engineers can directly check the allowable lifting weight for construction design, load calculation and safety verification, which saves project design time greatly.

Core Product Advantages

• Flexible Custom Configuration: 7 jib length options from 35m to 65m, matched lifting height and counterweight schemes, customizable according to actual project site constraints.

• Heavy Lifting Capacity：Max lifting load reaches 45 tons, suitable for hoisting heavy precast components, large steel structure segments and oversized formwork.

• Excellent Site Adaptability: Luffing jib design avoids building interference issues of horizontal jib tower cranes, ideal for dense downtown renewal projects.

• Safe & Stable Structure: Optimized mast + anchoring system, full load test verification, stable full-load operation and long service life.

• Easy Installation & Maintenance: Modular segmented assembly reduces lifting difficulty during erection; standardized spare parts simplify daily inspection and repair work.

Application Scenarios

• Super high-rise commercial & residential complex construction

• Long-span bridges, viaducts and large transportation hubs

• Large industrial plants and steel structure workshops

• Old town reconstruction & narrow-site urban renewal projects

• Prefabricated building large component hoisting jobs
