MANABE ZOKI CO., LTD.
MANABE ZOKI MDW Series Standard type Twin Deck Crane

Manufacturer: MANABE ZOKI CO., LTD.
Model: MDW Series
In recent years, requests for the optimum use of space on deck, rationality, and efficiency of loading work have increased. To meet these requests, deck crane styles are also increasing, as are traditional derrick loading styles.
We have been manufacturing the “Manabe-Hydraulic Deck Crane” with our long experience in high-pressure hydraulic-type deck machinery and our exceptional skill.
MANABE-HYDRAULIC DECK CRANE got “easy control” mechanics, which is the advantage of hydraulic, and we are considering how to reduce reliance on endurance in any weather, etc.
FEATURES
GREAT EFFICIENCY
The hoisting speed can be automatically changed in three steps for each load.
Especially, the 「MANABE-HYDRAULIC DECK CRANE」 is capable of over three times as normal speed when you hoist with light loads or lower with any loads. (Standard type)
In addition, you can operate easily with two control levers (for hoisting, luffing, and slewing), so you can work efficiently by smoothly controlling the speed smoothly for each angle.
WIDE CARGO SPACE
- Wide space is secured for work by reducing the minimum slewing radius, and it is possible to use the space on deck effectively.
COMPACT INSTALLATION SPACE
- It is possible to reduce installation space because of the inside access from fixed post to cab. (For the deck crane of over 245kN capacity) Acquired AWWF.
EASY TEST and MAINTENANCE
- MANABE winches and the hydraulic equipment in crane house are high-pressure type and compact, besides optimum position, so you can test and manage easily.
VARIOUS SAFE DEVICES
- 「MANABE-HYDRAULIC DECK CRANE」 equips various safe devices which are limit devices of hoisting and luffing, besides the float switch and thermo switch.
If any trouble happened such as power cut during a cargo handling, the cargo handling will stop immediately with the mechanical brake of spring-on type and counterbalance valve installed on each hydraulic motor
