Mobile service cranes are an indispensable tool in the field service industry. They help mechanics repair and maintain heavy equipment on-site, removing the need to transport it to a repair shop. Service cranes come in different sizes and lifting capacities to cater to various applications.
Several factors must be considered when selecting a crane for your service truck. The weight and size of the equipment to be lifted, the maximum reach and height required, and the crane’s lifting capacity. Choosing a crane capable of handling the heaviest load you expect to lift is crucial to ensure safety and efficiency. Other factors to consider include the mounting location, power source, and control options. Additionally, the type of crane, such as hydraulic or electric, should be selected based on the specific application and environmental factors, such as noise and emissions.
Lifting Capacity and Zones
Understanding the crane lifting capacity and zone charts is crucial for a crane’s safe and efficient operation. The load chart provides information about the maximum weight a crane can lift at different angles and boom lengths. The chart typically includes lines indicating the maximum weight a crane can lift at different boom lengths and angles, considering factors such as the crane’s configuration, counterweight, and other conditions.
Conversely, the zone chart provides information on the areas where a crane can safely lift a load. Typically includes a series of colored zones that indicate where the crane can operate safely and where it should not be used due to the risk of tipping or overloading. Considerations of the zones are the crane’s configuration, boom length, and other factors. I
When using a crane, referring to the lifting capacity and zone charts is essential to ensure it is used within its safe working limits. Exceeding the crane’s lifting capacity or operating in the wrong zone can result in accidents, equipment damage, or even loss of life. It is crucial to factor in the weight of the load, the position of the load, and the wind conditions when operating a crane. Doing so ensures safety and efficiency.
Hydraulic or Electric
Hydraulic cranes are the most commonly used type of service truck cranes. They are powered by a hydraulic system that uses fluid to transmit power. These cranes are renowned for their reliability, versatility, and ease of use. They are suitable for lifting heavy equipment, materials, and tools. You can find different hydraulic cranes, such as telescopic and knuckle boom cranes, each with unique lifting capacity and reach. Summits Advanced Safety Electronics (ASE) Phase 4 crane operating system standard on hydraulic cranes mounted on truck bodies. This crane operating system increases safety and performance with features that prevent use in unsafe conditions and crane overloading. Additional features provide crane operators with information and functionality to make performing a lift safe and efficient.
On the other hand, electric cranes use an electric motor to power the lifting mechanism, an alternative to hydraulic cranes. They are often used in environments where noise and emissions are a concern, such as urban areas. Electric cranes require less maintenance than hydraulic ones and come in different types, such as wire rope and chain hoists, each with unique lifting capacity, reach, and other features. When selecting an electric crane, consider the voltage and power supply required and the type of control options available. Summit’s electric hydraulic cranes come with a single-function wireless control system.
In conclusion, service cranes are a valuable addition to any field service mechanic. Choosing the right crane for your service truck involves considering various factors, such as weight and size, maximum reach and height, lifting capacity, mounting location, power source, and control options. Both hydraulic and electric cranes have unique advantages and disadvantages. Summit’s cranes range in lifting capacities from 4K to 14K, reaching 21 or 29 ft.
