Spider-Like Cranes - Portable

Portable, Small, Spider-like Mini Cranes

New mini cranes are helping lift heavy objects in tight spots or hard to reach areas. Spider like cranes can be placed on a rooftop to lift and lower loads, install glass panels, steel, metal, pipe, materials, HVAC etc.

The spider-leg design allows the operator to lift heavy loads closer to the center line of rotation – adding greater versatility.

Be flexible and save costs of renting or buying larger cranes.

The Smart-Rig spider like crane needs no fuel or gas. It is eco friendly running off batteries to operate the hydraulic boom arm jib and hoist that lifts materials.

Shop Cranes, Portable, Mobile Lifting Equipment

Shop Cranes: mobile portable small cranes

Smart-Rig Cranes can be used inside or outdoors or on rooftops. These are not just shop cranes - these are versatile floor cranes that work in and out of the work area. They can help lift heavy objects in a warehouse or be used for engines, building, installation, fabrication, and more. Shop cranes are made to help eliminate back problems lifting heavy materials in tight spots. Most mini cranes and small cranes are not versatile like the Smart-Rig shop crane.

Mini Cranes - Portable Floor Cranes - Industrial Lifting

Mini cranes are a hybrid floor crane and large crane and can come with battery power or electric. High end models are available with remote control and advanced electronics and hydraulics while the lower end models are basic with a hand pump jack and electric winch. Mini cranes not only can serve to lift indoors and outdoors with the height of the boom, but they can also be placed on a rooftop or structure to rig loads up from below. Rigging a load up to 400 ft. down is possible. Mini cranes vary in lifting capacity ranging from 1,000 lbs to 8,000 lbs.

Mini cranes or portable floor or mobile crawler cranes are portable and smaller versions of large cranes but more transportable and versatile, especially indoors and in tight spaces that require dynamic lifting solutions for materials. These mini-cranes are in use worldwide in industrial applications and some residential applications. Often referred to as "spider" cranes because of their asthetic nature, these mini crawler cranes are working within environments where large cranes cannot. Smart-Rig Cranes has the most economical minicrane on the market today with two models.. Lifting capacities and lift height varies by company and model.

Portable Jib Cranes, Small, Mobile

Small portable Jib Cranes are undeniably helpful in the workplace. They can lift enormous amounts of weight and make jobs quicker and more efficient. However, because of their enormous power jib cranes are also extremely dangerous. If a load drops there is almost no way to stop it or warn other workers to get out of the say. The resulting damage of jib cranes can result in serious injury and even death. 90% of crane accidents involve human error, so the proper preparation and training is crucial. By learning how to work jib Cranes safety, possible accidents can be greatly avoided.

Before operating a jib crane or minicrane workers need to take note of the Crane's characteristics including the jib Crane's weight, is the Host Rope rated for the load, is the load getting attached correctly? Knowing this basic information gets the worker prepared to operate the davit crane safely.

There are many types of cranes but industrial cranes are the most powerful and dangerous type of crane and the mental aspects of operating a large crane cannot be ignored. 90% of Crane-related accidents are caused by human error so the right attitude, hard work and basic knowledge are essential. An accident could kill you or someone else, so the serious nature of mentally preparing yourself cannot be overstated.

Most accidents that occur are caused by poor judgment, lack of attention or overconfidence. Run down a mental checklist before you begin. Ask yourself is you are physically and mentally prepared to work with the lifting machine/materials handling crane. If you are taking medication ask your doctor or pharmacist if it could affect your performance.

Being prepared also involves wearing protective clothing and equipment including steel-toed safety shoes, a hard hat and safety glasses to help protect against falling objects. A tucked in, long sleeve shirt is also essential.

Once you are physically and mentally ready for the rigging and lifting job you need to inspect the area where you will be working. Look for small leaks, clear the space away around the jib crane so that nothing is in the way and check the big crane itself. Test the fluid levels, controls and brakes while listening for unusual noises. Also, it's very important to check the Limit Switches that cut off power at the end of a crane's range of motion and the hook to make sure it's in perfect working order and right for the job.

There are three basic categories of cranes and each has its own characteristics.

Boom Cranes such as Tower Cranes and Truck Cranes are the most complicated and require rigorous training and qualification before using them. Boom Cranes have an arm which can be raised and lowered. This changes the "Boom Angle". Special emphasis on the setup of Boom Cranes can greatly reduce accidents. The most important thing about a Boom Crane is that it is level or it could cause severe structural damage and even tip over. Many Boom Cranes have outriggers (legs that extend and keep it level). Make sure they are on solid ground and keep the crane absolutely level. A bubble level on the base of the boom is a simple procedure to make sure the crane is level. When setting up a lift with a Boom Crane always use a load chart so you know the weight capacities for all the lifting angles. Every Boom Crane has its own load chart. One copy is attached to the crane and one copy is held by the supervisor. such as a Wall Crane or a Hammerhead Crane share many characteristics with Boom Cranes. They also have an arm which suspends the hoist Rope, Block and Hook. Jib Cranes have an arm which suspends the Hoist Rope, Block and Hook. However, unlike most Boom Cranes, a Jib Crane can not be adjusted for angle if it is locked in a horizontal position.

Before starting a Jib Crane lift, inspect the Crane for bent supports or misalignment. Make sure that you know the range of motion of the Jib Arm. Be sure that you know where the Emergency Stop Button and the Overload Indicators are located.

The third major type of Crane is the "Overhead Crane". An Overhead Crane, such as a Gantry Crane, carries its load along a bridge. It is attached to a building's walls, or to supports running up from the ground. Before using an Overhead Crane, make sure that the "End Stops" and "Bumpers" are secure and functioning properly. If the crane has legs like spider, ensure outriggers are extended. These devices prevent the Crane from running off the end of its rails and reduce the impact when a Crane reaches its End Stops. You should also test the "Trolley" (the moving portion of the Crane). Make sure that it can travel the full distance of the bridge without problems. Try the brakes to be sure that they work as well.

On any crane, the weight capacity limits should be checked before using and you should be aware of the safety devices that all cranes have. There are two kinds of devices -general Safety Devices and operational safety devices. General devices include bells and warning lights. Operational Safety Devices monitor and control the handling capacity of the Crane and include overload Indicators, emergency stop buttons and limit switches.
