Straddle Carrier
Straddle Carriers are basically lifting cranes mounted on tyres often used to replace gantry cranes for lifting and handling heavy loads in casting yards, factories, storage areas, ports. Straddles pick and carry load while straddling their load and connecting to the top lifting points via a spreader. These machines have the ability to stack segments and beams onto each other and shall be custom made according to contractor’s requirements.
Parameter information

 Straddle Carrier Crane Manufacturer & Supplier

Straddle Carrier is also called Rubber Tyre Gantry Crane or RTG Crane, Compared to normal gantry cranes which move on fixed rails, the Straddle Carrier has the flexibility to lift and steer heavy loads in any direction on motorized wheels. These Straddle Carriers' lifting capacities normally range from 5t to 900t. Each machine is custom-designed and fabricated under tight supervision to meet the client's requirements. 

Huada Heavy Industry Straddle Carriers are equipped with reliable system consisted of hydraulic powered winches or electric winches, motors, hydraulic powered rubber wheel, generator and centralize
PLC programmable control system. This machine comes complete with emergency features and multiple breaking systems for safe operation when handling heavy loads.

Straddle Carrier Crane Features

◆ Full hydraulic drive: The industrial straddle carrier adopts full hydraulic drive, including the traveling mechanism, steering mechanism, and lifting mechanism. 
◆ Strong site adaptability: adapt to various places without power supply, with its own power system, cement or asphalt pavement, strong site adaptability, and flexibility.
◆ Imported core accessories: The main hydraulic components pumps, motors, and reducers are all imported products, and the whole machine has strong reliability.
◆ Multiple steering modes: The operating mechanism has the functions of transverse running, longitudinal running, and 360° rotation with the geometric center of the vehicle as the center, forward, backward, and braking.
◆ Synchronous lift control system: The lifting adopts a synchronous shunt system and is equipped with leveling device to ensure the synchronous lifting and lowering of the load, the stroke of the lifting cylinder is detected by the pull rope sensor to protect the lifting safety.
◆ Automatic control system: The control unit adopts advanced electro-hydraulic technology, and the control actions of all systems are completed by solenoid valves, without the manpower to operate various valve groups.
◆ The most efficient material handling solution: Due to the characteristics of four-wheel 360° steering and lifting anti-sway, it has high material handling efficiency. The characteristics of low energy consumption, energy saving, and environmental protection can meet the needs of hoisting, transfer, and maintenance of large facilities.

Frequently Asked Questions


1.How to finalize the straddle carrier lifting height? 

The span and lifting height of the straddle carrier is customized according to client’s needs. Therefore, we need to get basic info and description of the working condition, handling material dimension, yard size so that we can proceed with design and offer.

2. What is the advantage and disadvantage of straddle carrier?

Straddle carrier crane has many advantages. Its structure has four additional legs, which makes the crane more stable, more efficient and safer in lifting operations. In addition, it uses a combination of components, Straddle carrier installation will be easier, reducing installation time and speeding up the schedule; and relatively small size, relatively light weight, can be flexible according to different positions to turn the equipment.
But there are some disadvantages, straddle carrier is less maneuverable, not suitable for long distance travel, and the requirements for road surface are also higher.

3. How are the straddle carrier wheels driven?

The straddle carrier can be divided into two modes: Hydraulic Drive and electric drive. The main power source of the hydraulic drive straddle carrier is the output power of the engine to drive the hydraulic motor for steering and running. The power source of the electric drive straddle carrier is mainly the generator output power to drive the electric system.

4. What are the requirements of the road surface for straddle carrier to work on?

The straddle carrier shall work on compacted road surface or concrete pavement surface.

5. Can you provide guidance for installation and commissioning?

There are two schemes for customers to choose from:
a: Free Remote on-line guidance: We have supported the site assembly & commissioning of straddle carriers by free on-line remote guidance 
that save much time& cost for our customers.
b: Huada will send engineers to customers site to guide site commissioning at client's cost.

6. How to maintain the straddle carrier? 

After delivery, we will send our installation, operation and maintenance manual of straddle carrier. Field users can perform maintenance according to the detailed information in the manual. 

7. How much does straddle carrier cost? 

Straddle carrier is a customized product, its cost varies depending on the requirements and specifications of each customer. The straddle carrier cost mainly depends on these factors: lifting weight, span, lifting height, power supply, actual working environment, and other special requirements. Therefore, if you want to get an estimated price, please send us the main information and we will give you a quick quote.
