Application

L type trolley heavy duty gantry crane is widely using in cement plant, granite industry, engineering industry, port, railway, civil aviation, food, papermaking, construction, electronics industries, and warehouses, etc.

Product Description

This gantry crane is composed of strong girder, L type support leg, crane travelling organ, trolley, electric equipment Etc. The frame adopts box-type welding mechanism, the L type single leg is welded structure in order to increases the work space, and it is convenient for the transportation, installment and maintains. Crane travelling mechanism adopts separate drive.

L type trolley heavy duty gantry crane is matched with a strong trolley, It is ideal for outdoor applications where lifting facilities are provided without the cost of a building or any supporting steelwork. They are also suited to indoor applications where existing building structures are not suitable to take overhead cranes, and where additional supporting steelwork would result in a loss of floor area. It can be constructed with a cantilever to allow handling outside the rail centers.

Design characteristic:

This kind of gantry crane beam design is just like a letter “L”, it could pass the big volume items, and this is a development of normal single beam gantry crane.

The lifting mechanism have TWO MODEL:

1)Wirerope electric hoist

2) Strong crab trolley

Crane Configuration:

Material: Steel plate material Q235 or Q345B ( similar international steel plate FE3 or FE52)
Steel structure: Strong Steel box type, seamless type, more strong and elegant beam.

Crane traveling motor: Soft start type
Wheel:Vacuum casting by our group, Inter medium frequency quenching

Main electrical parts: Schneider brand or Siemens brand.

Crane safety Feature

1. Limit Switch: Safety limit switches for stoppers prevent over traveling in all motions.

2. Anti collision device

When two crane traveling on the same rail, the cranes will install the following devices:

Anti-collision device, Infrared non-contact and inductive type limit device

Sound and light alarm device, Wireless anti-collision device

3. Weight overload protection device

Includes automatic stopping type lifting weight limiter and weight display device.

4. Lifting limit switch and traveling limit switch

5. Emergency stop system

6. Electrical protection

The main insulation switch, emergency stop switch, short circuit, Zero voltage protection, loss of field protection, Current overload protection, over speed protection, zero position protection

Phase sequence protection and adopted crane specially anti- vibration contactor etc.

7. Interlock device

It sets interlock device for the cabin door and the other door from cabin into bridge structure, when the door is opened, the crane cannot work.
