It has simple structure, light dead weight and easy operation. Speak to operation, we provide various bridge crane like single girder overhead crane, double girder overhead crane, explosion proof overhead crane...., different types of overhead crane have different ways to control. If you can choose the most suitable control ways for your bridge, then your lifting tasks will become easier.

There are main three control ways for overhead crane in crane markets, they are remote control, penedent control and cab control. If you want to choose the most suitable way for your overhead crane, this article will give you some professional suggestion

Overhead crane remote control

Crane remote control introduction: remote control also can be called radio control or wireless contro. A wireless remote transmitter with a series of buttons or levers is either held by the operator or is clipped onto a harness or belt worn by the operator. The remote transmitter sends a radio signal to a receiver unit mounted on the crane.

Features of crane remote control

1. the price of remote systems is reasonable, which making them more of a cost-effective solution and more in line with the cost of pendant control systems.
2. Using remote control liminates the dependence on being tethered to the crane itself—either via cab controls or pendant controls.
3. Remote control with better visibility helps improve productivity –helping with faster load positioning and damage control as the operator can better judge load and clearance obstacles from the ground.

REMOTE CONTROL FOR OVERHEAD CRANE

Overhead crane penedent control

Crane penden control introduction: A crane can be controlled by an operator on the floor using a push button pendant system that is attached to the crane itself. Many cranes, and especially like TRADITIONAL OVERHEAD CRANE, use pendant controls that typically hang down off the hoist itself and depend on festoon systems to allow them to move with the hoist. These controls are hardwired to the crane and require that the user be within a certain distance of the hoist in order to use them.

PENEDENT CONTROL FOR OVERHEAD CRANE

 

Features of crane pendent control:

1. Button: Up and down; left and right; front and back; start and stop; emergency. Dust-proof and waterproof , Safe and reliable
2. 6 buttons pendent control is widely used on wire rope hoist. 2 buttons pendent control is usually used on hook suspension type electric chain hoist,whereas, the 4 buttons pendent controls are used for motorized trolley travelling type electric chain hoist.
3. High impact resistance – can’t be dropped by the operator, since it’s suspended from the crane
4. Resistance to corrosion, moisture, dust, dirt, and grime
5. Insulated design provides shock resistance
6. Ergonomic design for comfort and less fatigue for the operaton

Comparison between remote control and pendent control

Remote control and penedent control, they are both reliable and easy to use, which accounts for the popularity they have retained over the years. However, they really work best for low-duty cycle lifts and jobs where the possibility of injury is extremely low, as the pendant makes the operator unable to be completely separated from the active loads

Although pendant controls can be used on almost any type of overhead crane, they are ideal for cranes that are in lower duty cycle classes. Because it is hardwired into the electrification system, the crane controls will always have power, so the operator doesn’t have to worry about replacing or charging batteries for a crane that doesn’t get used too often. Often, pendant controls are the preferred control method for EXPLOSION PROOF CRANES

Compared to radio controls, the pendant is always readily available since it hangs down from the crane itself. The operator doesn’t have to worry about finding it or keeping track of it like they would with a radio transmitter.

SINGLE GIRDER OVERHEAD CRANE WITH PENEDENT CONTROL

DOUBLE GIRDER OVERHEAD CRANE WITH CAB CONTROL

Cab Control for overhead crane

Crane cab control introduction: it’s easy to understand the cab control. An operator can control the crane from an exposed or enclosed cab attached to the crane and utilize one or two other co-workers on the ground who help guide and position the load using hand signals.

Features of crane cab control

1. Wide field of view, can see the whole site when lifting things, reduce accident rate. It is easy to operate, safe and efficient.
2. A floor view window. The windows glass of crane cab is tempered, which can reach to high impact and heat resistance.
3. Insulation: thermal insulation material will be inserted into the interspaces of crane cab for protection from noise and heat
4. The floor of crane cab is made with 3mm removable steel panels with anti-slip rubber mat.
5. A special protection design prevents abrasion of the wire insulation against the steel material.
