Electrical equipment

(for cranes with electric hoist):

• EB1 three-phase electrical socket with rotary switch
• EB2 three-phase electrical socket with main rotary disconnector and overcurrent protection, voltage monitoring relay and activation button, mounted on an electrical box with an 8-module DIN rail for mounting modular devices of the TH35 system
• SG additional electrical socket at the hoist, enabling power supply of suspended devices, e.g. vacuum grippers with an electric pump (option)

Control:

Ballast base:

• It consists of a steel bottom and top plate and concrete ballast modules
• The number of modules is selected depending on the load capacity and reach
• Detachable base, facilitating assembly, transport and possible expansion
   

Mounting methods:

• MB ballast - a crane not attached to the ground
• Mobile (without load) when equipped with a wheelset
• Support - adjustable swing feet
• Requires a hard, stable surface

Arm rotation drive:

NB manual drive

• Arm rotation caused by manual movement of a load or load chain
   

Working area limitation:

SO-B Adjustable arm rotation limiter (bumper), mounted on the arm

• Limits the movement of the crane arms in zones dangerous to the operation of the crane, people or nearby devices and installations, or facilitates work by limiting unnecessary arm movements
• The position of the stops is adjusted using screws and mounting holes

Rotation retarder:

SP Arm rotation decelerator (optional)

• It can only be used in the absence of an electric drive for arm rotation
• Prevents sudden or uncontrolled rotation of the arm
• Enables precise positioning of the load
• Standardly installed on all crane joints
• Principle of operation: friction with adjustable pressure force

Arm rotation lock:

SB Arm rotation lock (option)

• Allows you to securely lock the arm in the selected position
• Locking using a pin with an eye and a disc with holes at the lower yoke of the arm rotation axis
• The lock can be single-point or multi-point
• By default, the arm is locked at one point in the "straight" position
