Power Delivery
Cable reel is a frequent electrification method for big outdoor gantry systems. To release, collect, and store conductor cable for crane equipment, cable reels use a simple design that is either spring-loaded or motor-driven. They can be fixed either stationary or on a swivel base, allowing the cable to be deployed in a variety of angles and orientations.
When you stretch a cable out 50', 100', or longer, it may sag. If the cable is sagging or laying on the ground as a result of a lengthy track system, the benefit of enabling motorized traffic to pass beneath the gantry system is no longer valid.
To keep your electrical off the ground, overhead crane manufacturers can collaborate with you to create a system that uses lightweight beams or a series of poles. Alternatively, portable gantry cranes can be configured with longer extension cords to handle power sources that aren't always as close to the work area where the crane is moved.
Indoor/Outdoor Use
If your gantry crane system will be used outside, you'll want to think about the paint or finish you'll use, as well as the material. Because the crane will be utilized outside, you'll want to select corrosion-resistant materials like stainless steel or galvanized steel that can tolerate UV exposure, salt water, dampness, and high heat or cold.
To endure the elements, you'll want to think about features like motor heaters and insulated electrical panels. To protect the trolley and hoist, you can even construct a "dog house" or enclosed area. These can either travel on top of the hoist the entire time or serve as a designated parking area at the crane's finish.
Nearby Foot or Motor Traffic
If they'll be moving a lot of traffic, forklifts, and carts in and out of an area where they need to use their crane, most individuals will opt for a gantry crane. Forklifts can be brought in to pick up items, and trucks can be brought in and out for loading with a larger gantry system. That's most likely the case; the larger ones we've done have been for that purpose.
Support columns, such as those used with bridge cranes, take up valuable floor space and hinder worker movement throughout the building. It will be much easier for your personnel to move around in that region if you can remove those support columns.
However, you must consider what equipment or workers are functioning nearby while using any form of gantry system. When a gantry is travelling along a rail or track-or even when a portable gantry is being transported through different parts of a facility-important it's to be aware of any potential obstructions with which the crane can crash. Electrical panels, end trucks, controllers, gear boxes, and any other components placed to the crane's legs could be damaged by any form of impact.
To reduce impact exposure, manufacturers might get creative with the placement of controls, gear boxes, and panels on the legs.
Fixed Axle vs. Rotating Axle End Trucks
You may choose to upgrade to rotating axle end trucks instead of fixed axle end trucks, especially on outdoor gantry systems. The gears and bearings of fixed axle end trucks are enclosed, and in an outside environment, dirt, dust, and debris can get within the gears. This debris can clog the gears and cause the motors to overheat.
Rotating axle end trucks are built to be a little more heavy-duty and sturdy, and they often have fewer parts, making them easier to maintain. Even in unclean, dusty, and outside settings, the gears are enclosed in a constant oil bath that keeps all debris out.
Even the design of the drive's gears can make a difference. When compared to a worm gear drive, a helical or bevel gear drive can be preferable. In the case of a collision, a helical or bevel gear drive might roll back on itself, reducing torque on the gears. Because worm gear drives aren't designed to run in reverse, they could break apart in the event of an impact.
Crane Speed
Gantry cranes are best used in situations when speed isn't a factor. A bridge overhead travelling crane can travel at a very rapid pace, however gantry cranes normally move their loads at a crawling speed.
