In this guide, we'll explore the key differences between mobile cranes and tower cranes, helping you make an informed decision for your next project. Understanding these differences is crucial for project planning, budgeting, and ensuring safety and efficiency on your job site.
What Are Mobile Cranes?
Mobile cranes are versatile lifting machines mounted on wheeled vehicles or crawlers, designed to be transported to various job sites with relative ease. Their primary advantage lies in their mobility and flexibility, making them ideal for projects requiring lifting operations in multiple locations.
Types of Mobile Cranes
Several types of mobile cranes exist, each designed for specific applications:
- Hydraulic Truck Cranes: These are mounted on standard truck carriers and can travel on highways without special permits (depending on size). Our fleet at Parker's Crane includes several Grove hydraulic truck crane models.
- All-Terrain Cranes: Designed to navigate both rough terrain and highways, these versatile cranes combine mobility with impressive lifting capacity.
- Rough Terrain Cranes: Built specifically for off-road conditions, these cranes excel in construction sites with uneven surfaces.
- Crawler Cranes: Mounted on tracks rather than wheels, these provide exceptional stability but move slowly and require special transportation between sites.
Key Features of Our Mobile Crane Fleet
At Parker's Crane Service, we maintain a fleet of well-maintained, meticulously selected equipment to serve your projects perfectly. Some of our key mobile crane offerings include:

What Are Tower Cranes?
Tower cranes are fixed structures designed for long-term use on construction sites, particularly for high-rise buildings and large infrastructure projects. Unlike mobile cranes, tower cranes are stationary during operation and require assembly and disassembly for each project.
Types of Tower Cranes
Tower cranes come in several configurations to suit different construction scenarios:
- Static Tower Cranes: These are fixed to the ground using a concrete foundation and remain in one location throughout the project.
- Climbing Tower Cranes: These are built into the structure they're constructing, "climbing" upward as the building grows taller.
- Self-Erecting Tower Cranes: These smaller tower cranes can set themselves up without requiring additional cranes for assembly.
- Luffing Jib Tower Cranes: These feature a movable jib that can be raised to work in tight spaces where a horizontal jib might cause clearance issues.
When Tower Cranes Are Appropriate
While Parker's Crane Service specializes in mobile crane rentals, we recognize that certain projects benefit from tower cranes. We can assist with setting up smaller tower cranes when appropriate for your project. Tower cranes are typically preferred for:
- High-rise building construction
- Projects requiring long-term lifting in a fixed location
- Sites with limited ground space but significant vertical construction needs
- Projects where the cost of long-term rental of a mobile crane would exceed tower crane setup costs

Mobile Cranes vs Tower Cranes: A Comprehensive Comparison
1. Mobility and Flexibility
Mobile Cranes:
- Can be quickly deployed to different locations on a job site
- Require minimal setup time compared to tower cranes
- Can be rented for short-term projects, reducing costs
- Able to service multiple job sites in a single day
- Can be easily removed when not needed
Tower Cranes:
- Fixed to one location during operation
- Require significant assembly and disassembly time
- Best suited for long-term projects
- Cannot be easily relocated once assembled
- Provide consistent service to a fixed area
2. Lifting Capacity and Height
Mobile Cranes:
- Varying capacities based on model (our Grove GMK5150L offers up to 175 US tons)
- Generally lower maximum height than tower cranes (our tallest reaches 318.2 feet)
- Lifting capacity decreases as the boom extends outward
- More powerful models require larger footprints for stability
Tower Cranes:
- Typically designed for moderate loads at great heights
- Can reach heights of several hundred feet
- Consistent lifting capacity along the jib (horizontal arm)
- Higher capacity for loads closer to the tower
3. Setup Requirements and Costs
Mobile Cranes:
- Minimal setup time (hours rather than days)
- No foundation requirements
- Lower initial setup costs
- Higher daily operational costs for extended projects
- Requires trained operators, which we provide at Parker's Crane
Tower Cranes:
- Extensive assembly requiring several days
- Requires engineered foundation
- High initial setup and dismantling costs
- Lower long-term operational costs for extended projects
- Requires specialized crew for assembly and disassembly
4. Space Requirements
Mobile Cranes:
- Need sufficient ground space for outriggers and counterweights
- Require access roads for transportation to site
- Can work in tighter spaces with careful planning
- Need level and stable ground conditions
Tower Cranes:
- Minimal ground footprint once assembled
- Fixed radius of operation
- Cannot easily navigate around obstacles
- Height can create clearance issues with nearby structures or other cranes
5. Project Duration Considerations
Mobile Cranes:
- Ideal for short to medium-term projects
- Cost-effective for projects lasting days to weeks
- Can be brought in only when needed
- Flexible rental options (hourly, daily, weekly, or monthly)
Tower Cranes:
- Economical for long-term projects (months to years)
- High mobilization/demobilization costs make short-term use impractical
