Floor operated stacker cranes
 
The stacker cranes are used for high density storage of material. The goods to be handled are kept on pallets or in bins and stacked in high racks. Each individual pallet can be used/ retrieved independently, in any order, without disturbing other stored pallets.
 
Features:

Rugged structural steel construction.
Single crane can serve multiple aisles/racks.
Materials can be stored / retrieved in any order.
Safe operations with improved accessibility.
Lift capacity of 1000 and 2000 kgs.
Approx. 50-60% saving of floor space.
Reduced storage / retrieval time.
High density of storage achieved.

Storage system:
In floor operated stacker crane the operator operates the crane standing on the shop floor. The storage consists of high racks upto 8 meter (max.) height. The last loading level of pallet being at 6.5 meter (max), due to visibility limitations. Racks are segmented into horizontal bays and vertical tiers.
 
Equipment:
The stacker crane is an electrically operated equipment proven in use in rugged industrial environments. It is a single operator system designed to handle different types of loads on pallets (certain loads can be directly stacked).
 

Serves upto 8 m rack height with narrow aisle: Maximum utilisation of floor and space area
No derating of capacity at any level: Ease of operation to keep any load anywhere
Double deep and multi aisle storage system: Increased storage capacity
360° turntable for rotation: Permits rotation in narrow aisle
Fully electrical system: Lower operating and maintenance cost

The equipment has a fork attached to the vertical masts. These masts at the upper end are connected to a turn table. Which enables circular motion. The whole assembly is suspended on an overhead double girder. FLAME PROOF versions in 1t/2t models are available on request.
 
Movements:
Circular:
The turn table at the upper end of the mast facilitates 360 degree rotation in steps of 90 degrees.
 
Long travel:
The two ends of overhead double girders are supported on a pair of end carriages. The end carriages runs on rails laid throughout the length of the racks. This motion can be manual or motorised. The rails can be supported on racks or on RCC columns.
 
Cross travel:
The assembly with turn table can be moved across the entire length of the overhead double girder. This enables crane movement across rows of racks. Consequently same stacker can now service multiple rows of racks. This motion can be manual or motorised.
 
Hoisting:
Load is handled with the fork provided. A motor is provided to lift/lower the load. Overload clutch provided in models.
 
Options:

FLAME PROOF model
Multiple Aisle System
