LH Type Electric Hoist Bridge Crane

Description

LH Type Electric Hoist Bridge Crane is a bridge crane that uses a fixed steel wire rope hoist as the lifting mechanism, installed on a centrally driven double track trolley, and used in conjunction with the double beam bridge. It has the advantages of compact external dimensions, low building clearance height, light self weight, and low wheel pressure. It is an economical, practical, reliable, and easy to operate lifting equipment. The LH type hoist double beam crane is mainly suitable for the operation, assembly, maintenance, and loading and unloading operations of machinery manufacturing workshops, warehouses, material yards, power stations, etc. It can complete various transportation, assembly, maintenance, and loading and unloading operations.

Features

1. The LH electric hoist bridge crane is suitable for working in working levels A3 to A4, working environments with temperatures ranging from -25 ℃ to+40 ℃, and environments without flammable, explosive, or corrosive media. The lifting capacity is 3-63 tons, with a span of 7.5-31.5 meters.
2. The power supply of the crane is three-phase AC, with a rated frequency of 50Hz or 60Hz. The rated voltage is between 220V and 660V. The upper limit of allowable voltage fluctuations on electric motors and appliances is+10% of the rated voltage, and the lower limit (during peak voltage) is -15% of the rated voltage. The internal voltage loss of the crane shall not exceed 3%.

Technical Data

Options And Components

Main beam

The main beam is a box beam or H-beam structure, welded and formed from steel plates. The steel plate material is domestic steel (Q235B). The vertical winding is in accordance with Chinese national standards. All steel plates are subjected to shot blasting pre-treatment to achieve Sa2.5 level standardization. Before welding, the steel plates are carefully inspected and cleaned, usually by automatic welding machines (MIG or semi-automatic welding).

End beam

End beam is a supporting structure designed for lifting machinery, usually located at both ends of the crane, and its function is to provide stable support and balance for the crane. Cranes need to bear enormous weight and inertial forces during operation. Without the support of end beams, the crane is prone to imbalance or even overturning. Therefore, the role of the crane end beam cannot be ignored, as it is one of the key components for the safe operation of the crane.

Electric hoist

The electric hoist will do dynamic and static load tests, as well as ascending and descending pressure tests. The baking paint process is used to enhance the adhesion of the paint film and improve the appearance quality. The assembly line ensures product quality.

Crane remote control

Industrial wireless remote control is a remote wireless remote control device specifically used to control construction machinery or industrial equipment.

Crane control box

The surface of the control box has undergone anti-corrosion treatment Reasonable layout for easy maintenance Protection level IP55 Environmental temperature:<45 ° C, humidity<90%

Applications

This product is a regular crane widely used at open ground and warehouses to load, unload or grab materials. It has two controlling methods, ground controlling and room controlling.
