Ldp type electric single beam bridge crane




The wooden case



LDP type electric single-beam bridge crane (hereinafter referred to as the crane) is designed and manufactured in accordance with GB/ t3811-2008, JB/1306-2008 standards, with CD1, MD1 and other types of electric hoist supporting use, become a kind of off-track operation of light and small crane, belongs to ultra-low clearance crane, suitable for workshop workshop clearance height is low place.The electric hoist is located on one side of the main beam, which increases the service space of the hook and reduces the height and cost of the workshop.Weight of 1 ~ 16 tons, apply span of 7.5 meters to 22.5 meters, if there is a span of more than our standard range, we can also according to the requirements for the non-standard, working temperature 25 ℃ ~ + 40 ℃, humidity is 84% or less, in the absence of fire, * * And corrosive medium environment, work, and banned lifting liquid metal, toxic, flammable, explosive. For the convenience of users, with ground, remote control and operation control room three forms of manipulation.The control room is divided into two types: end face and side door.Design advantages: it overcomes the disadvantages of LD electric single-beam crane, such as poor stability, small effective lifting height, economical and practical;Disadvantages: low working level, not suitable for heavy workshop.The crane is equipped with ground control and remote control.

● Metal structure: the main beam is generally welded into a box type solid web beam.The beam is welded into a box with steel plate. For convenient storage and transportation, high strength bolts are used between the main beam and beam.

● Electric hoist: the electric hoist is used to lift heavy objects and move longitudinally along the main beam. Its structural characteristics are shown in the manual of electric hoist.

● Operation mechanism: the product adopts separate driving mode, which is completed by cone braking asynchronous motor, and the reducer adopts "one open and one close" gear reducer.

● Electrical equipment: the conical brake asynchronous motor is the supporting running motor.Electric hoist and the whole machine are equipped with safety devices, such as: lifting limit switch, limit switch at the end of the cart, etc.

Performance features:

● Reduce the height and cost of the plant;

● Car wheel distance, smooth operation;

● Compact structure, good rigidity;

● Raised the lifting height and increased the working space;

● Sensitive operation, low noise, safe and reliable;

● Economic benefits, beautiful modeling.

Ordering instructions:

1.The following main parameters of the crane should be determined before ordering: lifting weight, span, lifting height, track length, etc.In addition, special attention should be paid to the height of the plant.

Columns such as: lifting weight: 5t, span: 18m, lifting height: 6m, working class A3, track unilateral length: 110m.

2.When ordering, it is necessary to make sure that the conductive mode of the cart is sliding contact line, power supply position and control mode.

For example: the running mode is slide contact line, the power supply position is at the end of the workshop, and the operation mode is ground operation or cab operation.
