What is a 70 Ton Rough Terrain Crane?

A 70-ton rough terrain crane is a robust lifting machine with an impressive 70-ton lifting capacity. What sets it apart is its exceptional off-road capabilities, making it a go-to choice for construction projects on uneven or unpaved terrains.

Key Features:

  • 70-Ton Lifting Power: These cranes are renowned for their exceptional lifting capacity, allowing them to handle massive loads with ease.
  • Off-Road Prowess: Designed to navigate through rough terrains, they can access construction sites where traditional cranes might struggle.
  • Telescopic Boom: Equipped with a telescopic boom, these cranes can reach remarkable heights, expanding their range of applications.
  • All-Terrain Mobility: With sturdy wheels, all-wheel drive, and steering, they can maneuver through tight spaces with ease.

Why Choose a 70 Ton Rough Terrain Crane?

Now that we understand the basics of a 70-ton rough terrain crane, let’s explore the reasons why it might be an excellent addition to your construction equipment fleet.

Off-Road Capability:

The standout feature of these cranes is their off-road prowess. They are designed to navigate through challenging terrains, such as construction sites with uneven or unpaved surfaces. This means they can access job sites where traditional cranes would struggle, providing a significant advantage.

High Lifting Capacity:

A 70-ton rough terrain crane offers impressive lifting power, making it suitable for a wide range of applications. Whether you’re working on a construction project that involves heavy machinery, steel beams, or other substantial loads, this crane has got you covered.

Telescopic Boom:

The telescopic boom allows these cranes to reach considerable heights. Depending on the make and model, they can extend anywhere from 40 to 60 meters (about 130 to 200 feet). This feature is particularly valuable when working on tall structures or in challenging terrains.

How Does a 70 Ton Rough Terrain Crane Work?

Understanding the basic operation of a 70-ton rough terrain crane is essential, especially if you plan to operate one. These machines may vary slightly in their setup and controls, but the core principles remain the same.

The Telescopic Boom:

The telescopic boom is the heart of a 70-ton rough terrain crane. It extends to the desired height, and an operator controls its movement. The crane’s control panel allows the operator to extend and retract the boom, swing it left or right, and hoist or lower the load.

Safety Features:

Safety is a top priority when operating these cranes. They are equipped with various safety features, including load indicators, anti-two-block systems, and outriggers for added stability. Proper operation and adherence to safety protocols are essential.

How to Operate a 70 Ton Rough Terrain Crane

Operating a 70-ton rough terrain crane requires skill and attention to detail. Here’s a step-by-step guide to help you understand the process:

Step 1: Prioritize Safety

Safety should always be the top priority. Ensure the job site is free from potential hazards, and the ground is stable and level.

Step 2: Inspect the Crane

Conduct a thorough inspection of the crane for visible defects or issues. Confirm that all safety mechanisms are operational.

Step 3: Position the Crane

Drive the crane to the desired location and ensure it’s set up on stable ground. If necessary, extend the outriggers for added stability.

Step 4: Load the Crane

Safely attach the load to the crane’s hook using the appropriate rigging equipment.

Step 5: Operate the Crane

Using the crane’s control panel, the operator manages the boom and hook to lift and position the load. Be vigilant around any overhead obstacles or power lines.

Step 6: Monitor and Communicate

A spotter or signaler should assist during the operation. Clear and constant communication is crucial.

Step 7: Lower the Load

Carefully lower the load into its intended position, ensuring it’s secure before releasing it.

Step 8: Shutdown

Once the task is completed, power off the crane, retract the outriggers, and prepare it for transportation to the next job site.
