The cargo electric bicycle, also known as the freight or utility bike, is enjoying a renaissance and recognition as a cleaner, safer, and more efficient mode of urban freight delivery and passenger transport. As a human-powered and fuel-free vehicle, this form of active transport could bring even more benefits to our cities than other disruptive technologies.

Cargo bikes are proving to be versatile vehicles of change for urban business interests thanks to their economic viability. They also reduce the need for polluting and noisy delivery electric cargo trucks that contribute to urban gridlock. They make the streets cleaner and safer for pedestrians and commuting cyclists.

 

 

The bright electric future ahead, led by bikes

According to Germany Two-wheel Industry Association (ZIV), in the last year, electrically assisted cargo bikes have outsold electric cars in Germany with 39,000 sold versus 32,000 electric cars—an impressive when you consider that electric cars have benefited from substantial government subsidies, while e-bikes received only a small handout. Globally, Deloitte predicts that 300 million e-bikes will be out on the world's streets by 2023, representing a 50% increase over current numbers. These statistics seem to show that, despite all the attention around electric and autonomous vehicles, the future of e-mobility may actually be led by bikes. In the next five years, 40 million electric bikes will be sold worldwide, dwarfing the 12 million electric vehicles that will be hitting the roads over the same period.

We hear regularly that people with disabilities go by taxi transport or mobility scooter to the physiotherapy and sit there on a stationary bike. Why not visit a friend or take a trip with a (electric) tricycle instead? Because you always have to cycle yourself, there is always movement. When needed, the cyclist can choose between various degrees of electric pedal support and cycle more easily. More and more cyclists realize that their independence and mobility increase, and therefore choose the environmentally friendly electric tricycle.

 

The electric special vehicle (EV) revolution is speeding up, but it can only go so far without the necessary infrastructure and technology. As thinking shifts from fossil fuels to all-electric, visions of a brighter, more optimistic world come into view. The vision is to improve all aspects of performance and reliability and unlock the possibility of producing a battery solution that matches the performance of conventional gasoline and diesel vehicles, meeting consumers expectations, helping drive the uptake of hybrid and electric transport and supporting the Governments Road to Zero strategy—aiming to make road transport emission-free by 2050.

 

According to our experience, after spending a lot of time studying these two processes in depth, we found that these two production methods have more in common than differences. Powertrain equipment still provides components for power generation. The body shop is still making all the panels. In order to make cars, the assembly plant still assembles all these parts together. In general, there is no real difference. Especially by automating the supply next to the production line, we can help the assembly line respond to changes. For example, when an electric car production line needs to switch from a large combustion-powered car to an electric car, we will send the correct components or parts to the point of use. All that is needed is the notification in the advanced software. Once the system or assembly line supervisor makes these clicks, we will respond and go to the appropriate location to pull the correct one. The delay is eliminated, and the probability of error occurrence is almost zero.

 

When we talk about the hollow block making machine there are some different pictures and ideas of this machine in people’s heads so we need to specify what we exactly mean by it. A hollow block machine is a machine that produces hollow blocks using pressure and vibration to compress the concrete mortar into the molds and form the concrete blocks.

 

A lot of time and effort often goes into finding the right equipment for your facility. Purchasing a new automatic cutting machine is no different. With so many options, where does one start? Asking these five questions during the decision-making process will help ensure you end up with equipment that fits all of your needs.

Will my new cutting and stripping machine be flexible enough to process all of my current and future applications?

Unless you will be running the same few jobs day in and day out, you’ll want a machine that is as flexible as possible. It is best to focus on the extreme ends of the application range in regards to wire and cable size. For example, if the largest wire you currently process is 10 AWG, determine if there is a chance you will need to process 8 AWG or larger wires in the future. You should also determine if there is a chance you will require advanced features like a multi-blade cutter head (for processing multi-conductor cable jackets and inner conductors) or a rotary incision unit to make radial incisions through the various cable-layers when processing coaxial and other multi-layer cables. Being prepared for future needs will allow you to get the most out of your purchase.

How long will changeovers take and are tools required?

Most modern cutting and stripping machines are fully programmable, however, there are always several job specific mechanical parts (guide tubes, blades, etc.) that have to be changed between jobs. Changeover times can be minimized if these changes can be accomplished without requiring tools. The smaller your batch size, the more frequent your changeovers will be. A wire stripping machine with shorter changeover times will provide a quicker ROI and continue to pay dividends over the life of the machine.

What is a realistic production rate that I can expect with my new cutting and stripping machine?

When comparing datasheets for several different wire cutting and stripping machines, you will sometimes see a specification listed for Maximum Transport Speed. A high maximum transport speed does not always correlate to a high production rate, unless you are running longer lengths. The cutting axis and other machine specifications all contribute to the machine cycle time, so it is better to focus on the Maximum Production Rate listed for each wire length and application. It is always best to send wire or cable samples to the machine manufacturer before purchasing to get realistic production rates for your specific application.

What pre- and post-processing accessories are available for my new cut and strip machine?

Keep in mind that typical entry level cut and strip machines cannot be integrated with a full range of pre- and post-processing accessories. Determine what additional operations you’ll need and whether the manufacturer of the cut and strip machine offers fully integrated accessories for those operations. Typical operations include hotstamp or inkjet marking, coiling and stacking to name a few.

Another of the most basic accessories is a prefeeder. They are available in many different sizes and styles. The most basic models feed wire and cable directly by pulling it through motorized belts or rollers. The more advanced automatic wire prefeeder drives the cable reel directly, which is gentler on the wire or cable being fed. The most advanced models also feature a motorized reel lift and full enclosure for maximum safety. Make sure to specify a prefeeder that matches or exceeds the maximum acceleration and feed rates of your new cut and strip machine.

In the world of wire processing equipment, terminal crimping machines are like offensive linemen on a football team. They’re the unsung heroes that perform in the trenches out of the limelight. Applicators don’t get the same buzz and attention as laser wire marking or stripping machines, just like linemen are often overlooked in favor of quarterbacks or running backs.

Crimping presses haven’t changed much in recent years. But the tooling—that’s another story. Today, there are terminal crimping applicators equipped with RFID chips that store and relay setup and maintenance information. There are flexible applicators with multiple feed options. There are applicators with built-in cameras to aid setup. There’s even an applicator made from composite material.

Applicators are used to ensure quality and consistency in wire processing applications. They eliminate many problems that can arise from manual placement since terminals are automatically fed into position. Machine termination also ensures a complete cycle. In addition, crimp quality monitoring systems can be employed to ensure consistency and identify quality issues.

Harness shops usually crimp from hand or lose piece to applicator when they have high capacity. Although all crimping tools are designed to provide repeatable results, the crimper will produce the best throughput when used on a benchtop crimping machine. If used on fully automatic terminal crimping machines, this will be more true.

The automatic wire harness tape winding machine is used for professional wire harness winding and winding equipment. The tapes include duct tape, PVC tape, cloth tape, etc., used for marking, fixing and protection, and are widely used in automotive, aerospace, electronics and other industries.

Fully automatic cable coiling machine is a new model developed in recent years. In order to meet the requirements of high fficiency and high output, fully automatic models generally adopt multi-head linkage design. Most domestic manufacturers refer to Taiwan and other places. The design of the imported machine model adopts the programmable controller as the control core of the equipment, and cooperates with the manipulator, pneumatic control components and executive accessories to complete the functions of automatic wiring, automatic foot wrapping, automatic
