The seat has adjustment of longitudinal movement and the mechanism of an inclination of a back. The seatback has an adjustable head restraint that allows to change height and a corner of its inclination. The seat has the mechanism of a podressorivaniye of the torsion type with a gidroamartizator.
The upholstery of a pillow and back is carried out by special velor and has the high durability, resistance to attrition and stretching, and if necessary easily is removed for dry cleaning or washing.

Material of a protection of a cabin is not regulated; usually sheet steel is applied to these purposes. Glass in accordance with GOST 8435 — 57 can be applied to a protection of light apertures of a cabin, and also the cabin (glass nonshattering three - layer on butofolny laying). On jib self - propelled cranes it is allowed to apply to this purpose also glass in accordance with GOST 5727 — 57 (glass "stalinit" flat safe). Glass in accordance with GOST 8435 — 57 at blow does not break up to pieces, but can give a network of cracks. Glass in accordance with GOST 5727 — 57 at destruction breaks up to not cutting splinters of a certain size (no more than 32 mm, no more than 100 mm2). Falling from the big height of a significant amount of splinters is dangerous to the people who are below. Thereof "stalinit" it is not allowed to apply to a glazing of cabins of tower, portal and other cranes with highly located cabins.

If the cabin protection begins glass from a floor, application of an additional protection 1 m high from a metal lattice is necessary. The lattice has to sustain the crane operator's weight if an opportunity to rise on it is not excluded. The possibility of rubbing of glasses from two parties manually or has to be provided a mechanical way in the glazed cabins. For this purpose the necessary quantity of the transoms supplied with locks for their deduction as in closed, and abroach is arranged during the operation of the crane. In a glazing of cabins of the cranes working in the open air sun - protection guards are established.

The ceiling has to be arranged in the closed cabins. In open cabins existence of a ceiling is not obligatory. On cranes of bridge type in a ceiling of the closed cabins the hatch not less than 500X X500 in size for an exit to a bridge flooring is arranged. Through the closed cover so far the rain and snow should not get into a cabin.

Floor in a cabin of electric cranes has to be carried out from a tree or other nonmetallic materials excluding sliding both on a workplace of the crane operator and in places of service of electric equipment to be dimmed by standard rubber dielectric rugs. It is not allowed to arrange in a floor hatches for an entrance to a cabin.

The door for an entrance to a cabin can be oar or sliding. The oar door has to open in a cabin, except for jib self - propelled cranes, and also in the presence before an entrance to a cabin of the platform or the platform with the corresponding protection. From the inside of a door the device (a hook, a latch, etc. ) for its fixation has to be provided in crane operating time. At the cranes working out of the room a door, besides, it has to be supplied built in or the padlock.

The cabin sizes for separate types of cranes (tower, boom self - propelled, bridge) are regulated by state standards. If for this type of the crane in the standard there are no instructions on the sizes of a cabin or the non - standard crane is produced, then the sizes have to be appointed taking into account the following. To a cabin the place for the crane operator and the trainee would have to be provided and free access to the equipment located in it is provided. Cabin height (distance from a floor to any acting point on a ceiling) not less than 1, 8 m. The exception from these requirements is allowed for boom (self - propelled and hook - on), one - frame and suspended cranes. Cabins of these cranes can pay off on stay in them one crane operator (without trainee), and height is reduced to 1, 5 m if work is provided only sitting. The cab floor is carried out or from two layers of thick plywood, or from boards and a plywood covering. On a floor the directing sliders of a chair which can move on them along a cabin axis to 600 mm are fixed. It can turn around an axis and be regulated on height. In a cabin komando - controllers of control of crane mechanisms, a lighting guard, the index of a departure of an arrow and loading capacity, the measuring panel of the anemometer, the emergency switch, an oven, the fan and alarm lamps are located. The cabin is executed hinged and is fixed on eyes on an external surface of a tower near the arrow hinge. The cabin of the automobile crane with the management personnels and devices located in it is shown on rice.
