Lattice Boom Crane

Product Specifications

Technical details and manufacturing context for Lattice Boom Crane

Definition

A lattice boom crane is a specialized lifting machine characterized by its truss-like boom structure made of steel lattice sections. This design provides exceptional strength-to-weight ratio, allowing for lifting capacities ranging from tens to thousands of tons. These cranes are engineered for heavy industrial applications where maximum reach and load capacity are required, typically featuring crawler or truck-mounted configurations for mobility on construction sites, shipyards, and industrial facilities. The lattice boom, composed of interconnected steel members forming triangular patterns, provides structural rigidity while minimizing weight. A hoist mechanism with wire ropes and sheaves lifts the load, while hydraulic cylinders or winches control boom elevation and extension. The load is balanced through counterweights, and the entire structure rotates on a slewing ring. Load moment indicators and computer-controlled systems ensure safe operation within rated capacity limits. The crane's performance parameters, such as maximum lifting capacity (100–1600 metric tons), maximum boom length (30–120 meters), and maximum hook height (40–140 meters), are reference ranges that must be confirmed for the specific model and configuration. Materials typically include high-strength steel and alloy steel, with main steel grades ranging from Q345B to Q690D as per GB/T 1591. The working temperature range is -20°C to 45°C, and operation is limited to wind speeds between 13.8 and 20.7 m/s per ISO 4302. Electrical systems require 380–690 V AC (50/60 Hz, 3-phase) and 24 V DC control voltage, with ingress protection ratings of IP54–IP55. Counterweights range from 20 to 400 tons, and crane weight without counterweight is 50–800 tons. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The crane operates through a combination of mechanical and hydraulic systems. The lattice boom, composed of interconnected steel members forming triangular patterns, provides structural rigidity while minimizing weight. A hoist mechanism with wire ropes and sheaves lifts the load, while hydraulic cylinders or winches control boom elevation and extension. The load is balanced through counterweights, and the entire structure rotates on a slewing ring. Load moment indicators and computer-controlled systems ensure safe operation within rated capacity limits.

Frequently Asked Questions

What is the maximum lifting capacity of a lattice boom crane?

According to the directory reference, the maximum lifting capacity ranges from 100 to 1600 metric tons, depending on the model and configuration. Always confirm the exact capacity with the manufacturer for your specific application.

What are the typical boom lengths available?

The maximum boom length ranges from 30 to 120 meters. The actual length depends on the crane model and the lifting requirements. Verify the boom length with the supplier for your project.

What are the operating temperature and wind speed limits?

The working temperature range is -20°C to 45°C. For temperatures below -20°C, a cold-weather package is required. The maximum wind speed for operation is between 13.8 and 20.7 m/s; above 20.7 m/s, the crane must be secured. These limits are per ISO 4302.

What electrical specifications does the crane require?

The crane requires a power supply of 380–690 V AC (50/60 Hz, 3-phase) and a control system voltage of 24 V DC. The ingress protection rating for electrical enclosures is IP54–IP55. Confirm these specifications with the manufacturer for your site's power supply.
