Double drum roller is a kind of common medium and large road compaction equipment, for crushing sandy, semi-cohesive and cohesive soil, roadbed stabilized soil and asphalt concrete pavement layer has a very significant effect.

How to drive the double drum roller?

It can be started only when the front, back, left and right armies of the machine are clearly free of obstacles and people. Before the normal work of the road roller need to test run, to confirm the normal operation and brake, turn signal working mechanism performance is intact. Operation should be the first start and then vibration, combustion engine handle should be first to the middle speed, and then adjusted to high speed.

The coverage of the road roller is overlapped and the track needs to be kept straight. The road surface can be operated with reference to the distance between the steel wheels and the edge of the road, and when returning, secondary compaction is carried out with reference to the line just pressed.

When working close to the edge of the embankment, the necessary safety distance shall be left. The road shall be compacted from the inside out in accordance with the mountain road. When turning, the direction of the front wheel is controlled by the expansion and contraction of the steering pressure pump, and the steering is finally realized. When changing direction, it should stop first, and it is forbidden to vibrate on the hard ground.

Double drum roller operation specification:

A small amount of water spray, keep high temperature and slow speed, trapezoidal overlap, section implementation. Start on the outside of the road when rolling and gradually work towards the center of the road. Keep each repetition covering half the width of the steel wheel. Sharp braking, sharp curves, turning, steering, shifting gears, and stopping should be avoided on roads that have not been pressed or have just been pressed.

Stopping, forward or backward should stop vibration first, then shift gear.

Before starting the machine, it should check whether each working mechanism and each fastening part are intact. After starting the machine, it should be checked by test run to make sure that it is normal and that there is no trouble in braking and steering before it can be operated. The roller can be used to adjust the working line pressure by increasing or decreasing the counterweight. When the roadbed is soft, it should be rolled 1 to 2 times before turning on the vibration. The vibration frequency shall not be adjusted during construction. After adjusting the vibration frequency before operation, start the vibration first and then adjust the vibration frequency.

The main clutch is disengaged before adjusting the direction change, vibration starting clutch and brake. Fast gear cannot be used when going up or downhill. It is strictly prohibited to use the fast gear for sharp turning, and the vibration shall not be turned on when driving at high speed.

Double drum roller operation precautions:

The newly opened road should be carried out from the center to both sides, avoiding close to the edge of the roadbed incurring landslides. Pay attention to keep the scraper of the front and rear steel wheels flat and work well. Do not crush too soft roadbed. When the vibrating wheel needs to be filled with yellow sand to increase the weight, care should be taken not to have water to prevent freezing and cracking.

Starting or stopping vibration shall be done while driving. Vibration is strictly prohibited on solid road surfaces. When servicing, the engine is turned off, the brake is tightened, and the rollers are wedged symmetrically using a triangle of wood. The distance between two or more rollers should be maintained at more than 3 meters, and it is forbidden to drive in a longitudinal line or skid on the slope to avoid accidents.
